pursuant to United States Army Corps of Engineers (USACE), Alaska

District, Contract Ho. DACA85-91-D-0003 and Delivery Order Ho. 007,

Ecology .nd Enviro~ment, Inc. (E b E ) is conductiw an cnvironmtal

evallutfon md preliminary r d i a l aItcrmtives analysis of abmdoned

United Statu hp.rt..nt of Defame (WD) debris, hazardous and toxic

vutc (m), and petrol- oil lubriclntr (POL) at Attu, kchitka, Graat

Sitkin, .nd Kiaiu Ialanda in the Aleutian Island Chain, Alaska. The

project ru performed in rtSpOMe to a c o ~ r e r ~ i o r u l d a t e to USACE to

evalute potential hazards associated vith previous W D activities on

the islands.

Althowh previous evaluations of environmental damage on the

islands have been conducted, this project has betn designated as a

reconnaiss~ce-level study because the scope of activities is restricted

to confirming the existence and nature of prwiously identified

hazards. Specific objectives of this study are included in the project

scope of work, included in this report as Appendix F. This project is

not intended to provide extensive or complete site characterization,

contaminant fate determination, or quantitative risk assessment.

Consequently, preliminary remedial alternatives developed during this

project are intended for long-range planning purposes and are not based

on information and data sufficient for remedial design preparation.

This document provides specific background information and a con-

tamination assessment for Amchitka Island. Included are descriptions of

site background (Section 2). environmental setting (Section 3), sampling

procedures (Section 41, analytical results (Section 5), potential con-

taminant transport pathvays and receptors (Section 6), and summary and

conclusions (Section 7). This report augments the Debris Inventory for

hchitka Island delivered under a separate cover.

2.1 HISMRI f ie history of the lover Alaska Peninsula and the Aleutian Is l rnds

dates from 6,000 5.C. to the period of Russian colonization.

Alautr -re seafarin( people, traveling in by&-l ike b i d a r k u and

l iv ing i n underground, sod-coverd l o d g o hwn 4s barabaru.

The period of Rwrian coloaixstioa (1711-1867) had an oremhelmiw

and p a m a t impact on every aspect of Aleut culture. When Russian

explorers f i r s t arrived in the Aleutian Islands, a p p r o x i r t t l y 16,000

Aleuts occupied the region. Discovery of the valuable sea o t t e r pelt

led t o the exploitation of the iminal and the Aleut people by the

Russians. Whole vi l lages vere enslaved and forced t o hunt the sea o t t e r

for the Russim captors. Diseases spread rapidly and the Aleut people

vere decimated. By the mid l B O O s t the sea o t t e r population had been

grea t ly reduced and fever than 1,000 Aleuts renained.

The American colonization period (186'1-1940) began with the s a l e of

A l a s k a t o the United S ta tes i n 1867, and the fu r pi l lage vns renewed i n

earnest. In 1911, s t r ingent regulations vere adopted t o protect the

nearly ext inct sea o t t e r . No extensive surveys for Russian period o r

American period buildings o r foundations have been conducted in the

Aleutian Islands, and feu a r t i f a c t s remain.

American troops f i r s t landed on Amchitka Island on January 12,

1943. t o es tab l i sh an a i r f i e l d betveen Adak Island and the Japanese-held

Kiska Island. A fighter runvay (Fox Runvay), bomber runvay (Baker Run-

way), and a cross runvay (Charlie Runway) vere constructed (see Figure

2-1). Ouonset huts, administrative facilities, aircraft control and

warning facilities, gun emplacements, hangers, dockage, and other ancil-

lary structures vere constructed to support the approximately 16,000

troops stationed on Amchitka Island during the war. The United States

Armed Forces evacuated hchitka Island in August 1950, and most of the

renaining structures from the occupation vere removed in 1986.

During the 1950s a Distant Early Varning network (DEW line) vas

established between Alaska and Canada. A DEW line relay station vas

constructed ulna a 30-toot-diameter satellite dish on Amchitka Island to bridge the 400 mile gap between Adak and the Shearya Islands. The DBV

line relay station vas taken out of operation in 1961.

The Atomic Energy Commission (AEC) perforned three hfgh-yield

underground nuclear detonations at Amchitka Island. The tests Vera

conducted on October 29, 1965; October 2 , 1969; and November 6, 1971.

The nuclear tests vere conducted over Long period of time for three

basic purposear seismic testing, calibration, and warhead developmmt.

The three tests vere: Project Long Shot, a test vith an approximate

strength of 80 kilotons detonated at 2,359 feet belovground surface; Project Hilrov, a test vith an approximate strength of 1 mewton at a

depth of 4,000 feet belov ground surface; and Project Cannikin, vith an

approximate strength of 5 megatons at a depth of 5,075 feet below ground

surf ace.,

Radioactive-contaminated liquids vere generated during drillback

operations at the Cannikln test site and vere pumped back into the test

cavity, and radioactive-contaminated soils vere packaged and transported

off site for disposal. The AEC demobilized and evacuated Amchitka

island on September 8, 1973. In 1975, the AEC vas disbanded and most of

its activities vere transferred to the Energy Research and Development

Administration (ERDA). In 1979, ERDA became part of the Department of

Energy (DOE). W E representatives make annual trips to Amchitka Island

to continue monitoring around the test sites.

AplChitka Island is currently ovned by the United States Department

of the Interior (DOI) and administered by the United States Fish and

Wildlife Service (USPYS) as part of the Alaska Maritime National Vild-

life Refuge. The Naval Fleet Surveillance Support Command operates a

Relocatable Over the Horizon Radar (ROTBR) System on Amdritka Island.

The ROTHR is a forvard deployed system used to detect aircraft and ships

over the horizon. The system consists of a radar transmitter at the

northvest end of Anchitka, a receiver located across from Crovn Reefer

Point, a base camp, and a camp (North Camp) at the transmitter site. As

of December 1990, there were approximately 40 United States Navy (USN)

personnel and 120 civilian vorkers on the island.

2.2 i b W ~ B I m O l t T

hchitk. Island was part of the original Aleutian Islands National

Wildlife Refuge established by Executive Order Number 1733 in 1913

(Naval Energy and Environmental Support Activity [NEESA] 1990). The

island v u then ovned and managed by the WI. In 1943, the United

States Army occupied Amchltka for use as an advance base againat

Japanese forces in the Aleutian Islands. No fomal vithdraval of land

from the public douin occurred at that time.

In 1952, DOD relinquished Amchitka to W f . The Air Forca continued

to use portions of the island under special use pernits until 1961. The

AEC used luchitka from 1965 to 1973 for underground nuclear tests and

follov-up studies. The Alaska National Interest Lands Conservation Act

'(ANILCA), approved December 2, 1980, included Amchitka Island in the

Aleutian Islands Unit of the nevly created Alaska Haritiae National

Vildlife Refuge. The entire Island is currently under managtllent by the

USFVS (COE 1991). Under a memorandum of agreenent between USWS and

USN dated April 9, 1986, the Naval Fleet Surveillance Support Command

currently uses three parcels of land and a 100-foot corridor on each

side of Infantry Road, vhich bisects the island (NEESA 1990).

2.3 m o m mvESTI~TIONS

In 1977, the COE performed an inventory of debris at all Aleutian

military installations vhere major World War I1 construction took place.

As a result, detailed cost estimates vere prepared for removals at

Amchitka and other islands (COE 1977). An Environmental Impact Scate-

ment for the removal vork vas completed in 1979 (COE 1979).

The COE performed an environmental assessment in 1985 in prepara-

tion for the removal and demolition of structures abandoned from World

War 11. The majority of structures vere removed from the island by

1986. According to the contractor who performed the demolition vbrk,

55-gallon drums in various stages of disintegration were found scattered

throughout the island. The drums that vere nor corroded vere crushed

and buried on the island. The residue collected from some of the drums

was burned on site.

In 1988 the W E performed an environmental assessment of the three

underground nuclear tests which the AEC perforaed in the 1960s and early

1970s at hchitkn Island. Studies conducted by the AEC, the Batelle

)~..orial Institute, and several universities have also addressed the

effects of the three nuclear tests. Test results show trace levels of

tritium in water d soil smples in the imedirte vicinity of the Long

Shot site. According to the test results no other radionuclides had

escaped from the underground sites. Annual inspections are conducted by

DOE representatives at the test sites.

A study of petroleum contanination at Kirilof Wharf vas performed

i n 1989. Eight borrholes vere drilled at a proposed septic tank locs-

tion. Soil samples vere collected and some holes vere completed as

wnitoriu wells. Sample results shoved Total Petroleum flydrocarbons

(TPB) at levels from 19.5 to 635 mg/kg.

A Preliminary Assessecnt (PA) report vas completed in 1990 by NEESA

at the request of the Naval Facilities Engineering Command (WSA 1990).

The PA Report identified Bird Cape, Top Camp, Constantine Harbor, and an

apparent petroleum seep near Constantine Harbor as areas of concern (see

Figures 2-1, 2-2, and 2-3 for detailed site maps). It also mentioned

the presence of an asbestos dump near Constantine Harbor, tvo areas of

unexploded ordnance, and Saint Hakarios Ray, Omega Point, and East Cape

as areas of possible environmental damage.

100 feet hi& nearly surrounding the island. Oaly a few beaches occur

along the coastl ine and most of the island is fringed by a vave-cut

' beach of rock as vide as 330 fee t . There is one harbor, Constantine

Barbor, located on the Bering Sea s ide near the east end of the island.

The harbor is extreacly exposed during s t o m originating from the

nor theas t . ?e The eastern portion of the island is characterized by gently

ro l l ing te r ra in dotted v i th many shallow ponds having l i t t l e o r no

drainage connections. I n the higher central portion of t h e island the

area has more integrated drainage and wind erosion, v i th fever lakes and

patches of bare bedrock rubble on ridges over 200 fee t high. V e s t of

Chitka Point, the island kcones more mountainous v i th a aaxiaurn eleva-

t ion of 1,160 fee t . The westernaost portion of the is land consists of a

rocky and vindsvept plateau.at an elevation of approximately 800 fee t .

Elevations on AQchitka Island range from sea leve l t o 1,160 f ee t .

The topography is varied, consisting of mountains, a high plateau, lover

plateaus, and an intertidal beach. Except for the steep-sided rugged

mountains at the northwest end of the island, most of the land surface

has a rich grovth of alpine-zone mosses and grasses.

3.2 CLIUA'IE

The veather at Aachitka island is characterized by persistently

overcast skies, strong winds, and violent storms. Temperatures are mild

and their range is relatively small. In the coldest parts of winter,

usually in January, average daily maximums range from mid to upper

30 degrees Fahrenheit (' P) vhfle minimums fall to the 25 to 30' P

range, vith occuional temperatures into the teens. Extreme low tm-

peratures r w e to about 6' P. T-peratures begin to .oderate after

Pmbruaty. July a d August are uslully the v a r n t months. thyti-

h i g b from 55. to 60. P .re coroa in these months ( m S A 1990). T r -

perature extrrwr are derated by th* influence of the surrounding

Bering Sea. Beavy fog and gale-force vinds are also c o a o n throughout the Aleutian Islands.

Precipitation occurs from 200 to more than 300 days per year. The

me^ annual precipitation at hchitka Island is 32.6 inches. 5nov is

frequent fror November through April, when 30 to 100 inches fall (WBBSA

1990).

3.3 GEOLOGT

The Aleutian Islands vere forred i n the Quaternary and post-

Tertiary periods as a result of volcanic activity along the Aleutian

subduction zone. The islands represent the higher, exposed volcanic

peaks of the curving Aleutian arc. Host of these volcanoes are still

active. Glaciers sculpted much of the Aleutian Islands during the

Pleistocene epoch.

Bedrock and soils throughout most of the Aleutian Islands are

volcanic in origin. The soils of Amchitka Island contain large amounts

of organic matter and volcanically derived material. .

Three groundrater zonei have been identified on Amchitka Island.

These zones are hydraulically connected but exhibit differing rates of

permeability, retention, and conductivity. The zones are:

o Shallov vegetation mat, organic soils, and peat dewsits (turf ;

o Upper weathered and fractured bedrock, including unconsolidated eolian, marine, lacustrine, and glacial deposits; and

o Deep bedrock formations.

The shallov groundwater contained in the turf is often perched and

is generally associated vith surface vater features. Groundvatcr in

this layer accumulates in response to high vater holding capacities and

low vertical perrcabilities. Within the perched zones, water flows

through organic soils and peats and along the interface between these

soils m d btdrock. The flov paths in these areas are controlled by

topographic relief and the groundwater appears as springs at lover

elevations. In the lov-lying areas there m y be a hydraulic connection

between the shallov groundvater zone and the underlying fractured bed-

rock zone.

The middle unconfined graundvattr zone is found in upper vuthrred

and fractured bedrock 8nd other uncoasolidated materials that overlie

the less permeable bedrock forartfonr. The proundvater zone luy be

extensive across the island.

The less wathered bedrock that underlies the fracture zone is

geologically varied and exhibits variable hydraulic characteristics.

Groundwater within this unit interfaces vith sea water. The amximum

depth of this interface has been estimated at 2,625 feet. The

saltvater/freshvat@r interface is a mixing zone resulting froa dit-

fusion, ocean tides, and seasonal vater table fluctuations.

Groundwater froa wells is not utilized on Amchltka Island. Vater

is obtained from surface impoundments and springs.

3.4 SURFACE WATER

Host of the Aleutian Islands exhibit radial surface drainage ema-

nating from the peaks of the islands and flowing seaward. Warty small

drainages serve to transport vater only during high rainfall periods.

Amchitka Island is drained principally by streams that carry direct

runoff and sustained base flov. The base flow is discharged to the

AUCBITRA ESLAPin/car recycled wper

"*Jur? and inrnnnmml

streams and many lakes from a moderately permeable shallow groundvater

reservoir. Because the water table is a t o r very near the land surface

over most of the island, the shallow groundvater flow occurs within t h e

tundra, s o i l , and peat, a s w e l l a s within t h e upper feu hundred meter?

of underlying volcnnic rocks. The qua l i ty of the surface vater and near

surface vater is good. Sal t spray driven by vind over Aachitka Island

from the adjacent ocean influences the composition of r a i n f a l l , as

i n d i a t d by r a t i o s of sodium to chloride i n va t e r of the surface and

shallov subsurface system.

Hundreds of sul l , shallov ponds cover b c h i t l u Island. There a r e

generally two typma of ponds: l o v l d ponds occupy iq deprcasions in

the pa t mat, gemra l ly found i n the southeastern and cen t r a l regions,

uui ponds pe rchd i n bedrock dapreasions, found m i n l y i n the northwest

ragion. Pods a r e wrt p l m t i f u l i n the southeast aect ion of the island

v h r e there a r e roughly 26 ponds per aqrure mile. The ponds range In

vld th up t o 330 fee t and in depth from less t h 3 f e e t to more t h 10

tee t . The s t rum i n the sou theu te rn portion of M i t k a graera l ly

str- var ies according t o weather conditions and moisture lmvel of the

vegetation and so i l . Generally, the s t r e a r s a r e low i n gradient and

velocity.

Streams in the cent ra l region are mostly 6 t o 13 fee t vide and 8 t o

12 inches deep. They a l s o have changing f lov charac te r i s t ics dependent

on veather and s o i l moisture.

Northvestern region streams flow through deep tundra-covered

valleys. Host of these streams a r e 6 to 1 3 f e e t wide and 10 t o 14

inches deep. They have a greater flow veloci ty and volume than s t r e a m

in other areas.

Drinking vater on Amchitka Island i s supplied from three separate

surface vater sources. Vater fo r the Base Canp is dravn from Con-

s t an t ine Spring north of Baker Runvay. The va te r is retained i n a

concrete dam and stored i n a pump house vhere i t is t reated v i t h

chlorine. Vater fo r the North Camp is supplied from a h i l l s i d e seep,

and vater for the receiver s i t e is d r a m from a lake. Both supplies a re

a l s o t reated v i t h chlorine.

3.5 BIOTA

3.5.1 Avifauna

According to USFVS, 131 species of birds have been recorded on or

near hchitka Island. Evidence of breeding on the island has been found

for 28 of these species. Species known to nest on Amchi tka include bald

eagles, gulls, ravens, rock ptarmigan, peregrine falcons, Lapland long- ---- spurs, and mallard ducks. Attempts at reintroduction of the Aleutian

Canada goose by USFUS have failed to establish a breeding population

thus far. Huasn disturbance of tundra on the southeastern end of the

island h a fostered the growth of distinctive localized grasses in and

around b e r d areas. These areas encircle much of the remaining debris

or contuination, and are exploited by several bird species as nestiw

sitms (COB 1965; 1990). During th 1991 fieldvork, bald emglcs

=re observed nesting vithin 100 yards of the Saint n h r i u s Bay debria -- - area.

3.5.2 ?erremtrial

iimchitka Island has no indigenous species of terrestrial w.1.

The Horvay rat was apparently intrducd to tbe island during World

War I1 and still inhmbits bchitlu. Tbe arctic fox WM introduced in

1921 for fox farming, decimating the bird population. Betwen 1950 and

1960, the USISWS extirpated the fox from hchitka (COE 1985).

3.5.3 Hariae W

Various marine mammals occur in the coastal waters of Aachitka

Island. These include sea otters, northern fur seal, harbor seal, and

Steller sea lions. Steller sea lions are knovn to haul out at Saint

Hakarius Point. The field team also noted approximately one dozen sea

lion and fur seal skeletons washed ashore at Saint Hakarius Point during

the 1991 field season.

The surrounding seas support numerous cetaceans, including Bai rds

beaked vhale, blue vhale, bovhead vhale, Curviers beaked whale, Dolls

porpoise, finback whale, gray whale, harbor porpoise, humpback vhale,

killer whale, minke vhale, Pacific right whale, Pacific vhitesided

dolphin, Sei whale, spern whale, and Steynegers beaked vhale. Many of

L these mammals are listed as threatened or endangered (COE 1985).

3.5.4 Presbuater Plsb

b c h i t h Island supports only six species of freshvater fish. Both

the Dolly Varden char and the three-spine stickleback occur in land-

locked and anadrwous foras. ?he coast-range sculpin occurs in many of

the bodies of fresh water on the island. Pink, red, and silver salwn

spavn in various small stream on Aachltka (COE 1985).

3.5.5 krill. P i d l The urine flsheri*. at JUchitIu Island are abundant, md many

special are colwrcimlly exploitd. Comercia1 vessels operating in tha

area harvest salmon (hue, pink, and rrd), king crab, Pacif ic halibut, Pacific ocean perch, Pmcific cod, sablefish, and vallcyed pollock (m 1985).

3.5.6 Vegeutlam

Terrestrial vegetation on bchitk. it characterized as a uritime

tundra having relatively few plant tuu. This tundra is utre.cly - fragile and susceptible to physical or chemical damage. &aches and

disturbed areas around kras are dominated by grasses. Bistorically,

secondary plant succession in disturbed areas on the island has been

very slow (COE 1985).

Aquatic vegetation In the island is also of limited diversity.

Streams are dominated by mosses and livervorts, vith buttercup and vater

milfoil also present. The ponds and lakes are dominated by vater

milfoil. Other aquatic plant species found in the ponds and lakes

include pondveed, buttercup, and blue-green algae (COE 1985).

3.5-7 Aquatic Invertebrates

The streams, ponds, and lakes of Amchitka Island also support a

microinvertebrate population of lov diversity. Pour invertebrate phyla

comprise a majority of the animal biomass in the aquatic environment.

Soft mud environments on the island support annelids and nematodes,

vhile oligochaetes are found in gravel and s a d stream bottoms. Mol-

lusks, represented by clams and snails, are found in all ponds and

lakes. Insects and crustaceans are also common in the ponds and lakes.

Documented types include isopods, caddis flies, vater boatman, diving

beetles, blackflies, and midges.

3.5.8 T h r e a t 4 Pad Emhugered Species

Nine threatened or endangered species are associated vith Amchitka-

Island. The vaters surrounding the island support the follovlng eight

endangered species of vh.le: blue, bowhead, f inback, gray, humpback,

Pacific right, Sei, and sperm vhles. These species are known to

frequent the area around Amchitka Islmd, although the extent has not

b u n vell d o c m m t d (WE 1985).

One threatened avian species, the Aleutian W d a goore, may

1 ---7

frequant Amchitka. Attmpts at reintroduction to the Island havr been 1 u d e since 1971 by the USF'VS. Although no viable breeding population

exists yet, b t h the goome and its habitat ate protected under the I

Endanger4 Specits Act (COE 1985). A

Tbe Steller s u lion, knwn to frequent A.chitkals waters md haul out on its beaches, has undergone a sharp population decline in recent

years. At this tim, it is listed as a threatened specles. ]I . 3.6 lbllD USE

Portions of Amchitka Island are currently used by the USN Fleet

Surveillance Support Cornand as the site of a radar installation. The

radar base has a staff of approximately 40 navy personnel and 120 civjl-

ian vorktrs (E & E 1991). Access to the radar base is controlled by the

USN and by Piquniq knagement Corporation, the Navy's service contractor

for the island. All other areas of the island are administered by the

USFUS as part of the Alaslta britime National Wildlife Refuge. Visits

by WE and USPVS representatives make up the remainder of the human use

of the island.

Kirilof Uharf in Constantine Harbor makes Amchitka Island readily

accessible by boat. All areas visited during this project can be

accessed from established roadvays.

4.1 -fSf Pialdvork v u conducted from Septclkr 5 to 11, 1991. The field

team consisted of:

Brim nilkill !I 4 B Team h d a r Sheila Flaming I3 & E I h g i m r Brad A d u n B & L Bydroplogist Chris Parrcr E C E hvitommtal Scisntist Paul kverty COE On-rite Rtpreaentmtive

All lodgiw, nmals, and on-site tranrportation ware obtained

through Piquniq nu-t Corporation, tha b u a oprations contractor

for UYI on bchitka Island.

Tbe extensive road system on hch i t lu Island has b u n rintained

for use by standard tvo-vhnl drive vehicles (primary rods) and four-

vheel drive vehicles (secondary rods). The Bird Cape and Top Camp

sites required four-vhatl drive for access. All other sites vere

accessed vith two-*eel drive vehicles.

A total of 33 samples were collected on Amchitka Island from

September 7 through September 10, 1991: 17 surface soil samples, six

drainage sediment samples, five water samples, and five drum product

samples. Included in this total were one background surface soil

sample, one OA and one QC rinsate sample, one QA and one QC soil

sample, and one QA and one QC sediment sample, which vere collected and

submitted to the project and QA laboratories. Sanples were analyzed for

polynuclear aromatic hydrocarbons (PAH), polychlorinated biphenyls

(PCBs), fuel identification (Fuel ID) and quantification by mdified EPA

method 8015, and the following Resource Conservation and Recovery Act

(RCRA) metals: (arsenic, barium, cadmium, chromium, lead, mercury,

selenium, silver) (Hetals) (Table 4-1).

4.2 OBIBCI?WS

This project vas primarily intended to serve as a preliminary

reconnaissance of potential RTU and POL sources that nay present a

hazard to human health and/or the environment. Accordingly, the

folloving specific sampling objectives were defined:

o Determine the presence and nature of hazardous substances and contamination sources;

o Approximate the extent of soil contamination it each iden- tified vaste source location where possible; and

o Determine the presence of contaminants in surface viter, runoff, and sediments near identified vaate sources.

~aaera1 field activities conducted to acconplirh the objectives

were as follovrt

o Collection of surface soil samp1.r from Bn and POL dis- posal locations;

o Htlsuremmt of visibly stained roll a r m uul inventory of potential vaste containers;

o Collection of suplea from a percentye of representative poteatid vutc containers; and

o Collection of samples from surface runoff, streams, and/or stream sadiments near identified waste sources.

4.3 !ummmUW;I

4.3.1 S u p l e hcatioas

In keeping vi th the project objectives, all sanple locations vere

selected in a biased manner. Areas of potential E N or POL containers,

and stressed vegetation and stained soils were identified through a

visual reconnaissance of the site. These locations vere then sampled as

they represented the most likely areas of contamination. In areas vhere

a release to a drainage was apparent, samples vere collected along the

release path and drainLge path to deternine the extent of surface con-

taminant migration. Analytical parameters were chosen based on visual

observations in the field and previously collected information. Fuel

ID, PAH, and Metals analyses vere selected for areas vhere WL

constituents vere the only suspected source of contamination. PCB

analysis was selected only for areas where the presence of electrical

equipment was observed or likely, and in areas where contaminant sources

vere not reallily identifiable.

4.3.2 m l e m a and Matrices

Sample types vere determined by location and matrix. Grab samples

were collected from EITU and POL containers vhenevtr sufficient volumes

of contents were present. All surface vater samples were also grab

samples. Surface soil grab and sediment grab samples were collected

from 0 to 6 inches in stained areas or obvious releases. Composite

surface soil and sediment samples were collected from 0 to 6 inches in

are- not having distinct releases or those having stains covering larm

areas of soil. Composite suples vere prepared by using three or four

aliquots as determined by the team leader at the time of sampling.

4.3.3 -1. Collection Wethods

All samples vere collected in accordance with the Chaical Data Acquisition Plan (E C E 1991r). Prrclalned, stainless steel trovela and

bwls vere utilized to collect surface soil samples from the 0- to

6-inch interval. Grab samples vere placed directly into prelabeled

sample containers. For composite samples, soil was collected from three

to four representative locations. These four aliquots vere thoroughly

homogenized in a precleaned, stainless steel mixing bowl and transferred

into prelabeled sample containers.

Surface vater samples were collected by dipping prelabeled sample

containers into the body of vater.

Sediment grab samples vere collected by using prelabeled sample

containers as coring devices. Sediment grab samples were collocated

with water sanples and collected only after vater sample collection to

avoid unnecessary turbidity in vater samples. Composite sediment sam-

ples vere collected using aliquots from three to four representative

locations. The aliquots vere thoroughly homogenized in a precleaned

stainless steel mixing bowl and transferred into prelabeled sample

containers.

Containers of HTU or POL products vere sampled by filling pre-

labeled sample containers using dedicated glass thieving rods. Sorbent

pads vere placed around the bases of containers being sampled and

beneath sample containers to collect any spills. Used thieving rods

vere broken and placed inside the container after sampling was com-

pleted. Sorbent pads vere also placed inside the containers after

sampling was completed.

Quality assurance/quality control (QA/QC) soil samples vere

collected using the same methods as other samples of similar matrix.

Sampling equipment blank Irinsatc) samples were prepared by rinsing a

clean supling device vith orgmic-free deionized water and collecting

the water in a prrlabeled sample container.

4.3.4 hple Uodlw and S h i p a t A11 suplcr vere preserved upon collection and stored under chmin-

of-custody procedures until shipment. N1 suples arrived at the

project and M laboratories in good condition and adequately preserved. All tuple holding times vere met vith'the folloving exceptions:

o m p l e 029YA vas analyzed using modified method 8015 one day after the maximum alloved holding time;

o Sample 032SD~vas reanalyzed 16 days after the maximum alloved holding time, due to 'internal QC failure; and

o Samples OlTVA and 0 1 W A vere received at the project lab- oratory two days after the maximum allowed holding time.

See Appendix A for a complete discussion of these samples.

4.4 SIuIPlnG A r x l m T m S

The sampling activities conducted on Amchitka Island are detailed

in the following paragraphs. Descriptions have been organized by site

as defined in the Amchitka Island Debris Inventory (E h E 1991). A11

samples vere collected and packaged in accordance vith the Chemical Data

Acquisition Plan (E & E 1991).

4.4.1 Base Camp Area -ling Activities

At most locations in the Base Camp area, no evidence was found of

Bn o r POL containers or contamination. Therefore, the following Base

Camp area locations vere not sampled:

o Aircraft Debris Area,

o Constantine Barbor/Kirilof Wharf,

o Saint Hakarius Bay Dcbris Area,

a Saint Hllurius Point Debrjs Arei,

o South Bight W r r y , and

o Submarine Netting Floats.

Descriptions of these locations may be found in the Amchitka I s 1 4

hbtir Invantory (B 6 B 1991).

Supling of B u r Camp loutioaa occurred on S.ptrb.r 10, 1991.

this project. See Fiwre 4-1 fur a srtolry of m e Cup area .ampling

locat ions.

- The Asbestos'Oisposal Area near Constantine Barbor vas listed in the PA. Based on observations raade during the field team's visual

recon~issance, samples were collected in this area. The field team

noted a distinct sheen on pooled vater immediately dovngradient of an

area marked with signs indicating that it-vas an asbestos disposal area.

Sediments underlying this water had a distinct rust color. One vater

sample (033VA) and one sediment grab sample (032SD) were collected.

The field team also performed sampling activities at the location

of a ground discharge mentioned in the 1990 PA. Sediments at the

discharge vere rust colored and appeared to be centered around a small

portion of steel pipe protruding from an emban!ment. The field team

noted that algae vas groving on the stained sediments. Upon further

reconnaissance, the field team found that the pipe had been removed,

leaving only a ditch and the portion visible in the embankment. One

composite sediment sample (03150) was collected at this location.

Mo samples vere collected at the Constantine Barbor soil contam-

ination location described in the 1990 PA report. Reconnaissance of the

area indicated that boreholes and monitoring vells completed as part of'

a separate study vere sufficient to provide adequate information on any

POL contamination source in the area.

5.4.2 Bird C.pc Area Sampling Activities

Sampling activities at the Bird Cape area vere conducted on

September 7, 1991. Sampling locations vere selected bared om a site

reconnaissmce conducted on Scpteabcr 6, 1991. See Figure 4-2 for a

a-ry of Bird Cape area saaplinp locations.

4 4 2 . 1 SPpliw mt Bird C.pc Area Drm Group Loenti-

The eight drum groups at the Bird Cap a r u prrsanted the most likely locatio~ of BTY and POL sources. A11 drrvll groups vere extrmnly

veatherd and in fair to poor condition. Wberever possible, saap1.s of

drum contents w r e collected to ch.racterize the wastes present. T h

folloving paragraphs detail the sampling activities at u c h of the drum

groups. See Pipre 4-2 for drum group locations.

Drum Group 1 consisted of 90 to 180 drums psrtially buried in a sand bluff. The d r m appeared to have been stacked and aubsrquently buried by shifting sands. %any of the visible drums were corroded and

' decaying, vith POL products visible in a small nruber. There was no

stained soil or stressed vegetation apparent. Vegetative growth in this

location was quite thick and consisted mostly of grasses. Tvo samples of drum contents (OOlDR, DO2DR) vere collected, along vith tvo composite

soil samples (003SL. 004SL), and one soil grab saaple (005SL). The soil

grab sample vas collected adjacent to the drun from which the field team

collected sample number OOIDR.

Drum Group 2 consisted of 65 to 130 drums on the ground surface

vithin a building revetment. The drums vere arranged in rows and appear

to have been stacked in two layers. Vegetation surrounding the drum

group vas thick, with some stained soil and stressed vegetation visible

near the center of the group. One sample vas collected of drum contents

at this location (OIIDR). A composite soil sample was also collected

from Drum Group 2 (007SL).

AnCHITRA ISLAND/ car

A total of nine drums were found at Drum Group 3. The drums vere

located in a barren, sandy area approximately bO feet in diameter. Some

staining of the soil vas evident, as vas a slight petroleum odor. A

small amount of a gasoline-like product vas found in one of the drums.

A triplicate composite soil sample (OOBSL, 009SL, OlOSL) vas collected

from stained soils surrounding this drum group.

Drum Group 4 consisted of approximately 200 drums in poor condi-

tion. The drums vere arranged in rows on the ground surface and formed

tvo distinct groups several meters apart. Vegetation at Drum Group 4

vas thick, and no stained soil or stressed vegetation vas evident. One

composite soil sample vas collected from soil at the bases of several

intact druns (014SL).

At Drum Group 5 , the field team encountered 14 drums lying in a

vetland area. Oily sludge, stained sediments, and stressed vegetation

vere evidmt downgradlent of the drum. A distinct sheen was visible on

standing water near the drum. One suplt of the contents of a drum

that had released most of its contents to the surrounding sediments

v4s collected (016DR). A so11 grab sample vas collected 10 feet dom-

gradient of the drum group in an apparent migration route (OlfSL),

Drum Group 6 consisted of i S to 150 drums partially buried in a

sand dune. Vegetation at this location v a thick, and no stained soil

or stressed vegetation was evident. The drums vere arranged in rows

'with many appearing to rest on an underlying layer of druns. The field

rean d3d not locate any drums containing product. One c~lposite soil

sanple vas collected from this location (018SL).

Drun Group 7 consisted of 11 drums in an area of short grasses.

Tvo areas of stained soil (less than 10 square feet) were noted around

the bases of the drums. The field team collected one sample of drum

contents from a drum near one of the stained areas (012DR). A composite

soil sample vas collected from the stained areas (013SL).

An estimated 10 to 20 drums comprised Drum Group 8. These drums

were noticed protruding slightly from a bluff at the parking area. The drum group is mostly buried vithin the bluff. The visible portions of

the drums are in poor condiiion, and no evidence was noted of stained

soil or stressed vegetation. No samples were collected at this loca-

tion.

4.4.2.2 Snrpling at Other Jacaticrns

An additional cwposite soil sample vas collected at a debris pile

approximately 20 meters south of Drum Group 1 (006SL). This debris'pile

contained remains of an amphibious vehicle, and miscellaneous wood and

metal debris.

A vater sample vas collected from a stream on the north side of the

parking area (017UA). This stream vas selected because it drained a

pond that appeared to collect runoff from much of the debris-containing

area at Bird Cape.

A baclyround soil grab suple v8s also collected fro. an upgrdiant

art. one-quarter mile eart of the parkiw a r m (OZlSL). Iht location of t h i ~ sample vas on hillside upgradiant from the military debris. Tbc soil in this location n s overlain by 6 inches of dame vagetative

uterial.

4 . 3 Top C s q bran Supling Actiritia

Supling activities at the Top C u p area were conducted on

September 0, 1991. Sampling locations were selected bosed on a site

reconnaissance conducted on Septsber 6, 1991. See Figure 4-3 for a

'summary of Top Canp area saapling locations.

4.4.3.1 Sampling at Top Camp Area Drum Group Wtiocls

Samples vere collected at three drum groups in the Top Camp area.

These drum groups presented the most likely locations of Im or POL

contamination. No samples of drum contents were collected, as no drums

containing product were found.

Drum Group 1 consisted of 120 drums in poor condition. Approxi-

mately SOX of the drums had decayed so that only drum rings remained.

The drums vere located on the northeast side of a rocky turnout along

the access road to Top Camp. No stained soil or stressed vegetation vas

apparent. One composite soil sample vas collected from soil at the

dovngradient side of the drum group (023SLl.

Drum Group 2, consisting of 17 drums, was located at the southvest

end of the turnaround. All drums in this grorrp vere in poor condition.

No stained soil or stressed vegetation vas noted. One composite soil

sample was collected from the dovngradient side of the drum group

(022SL).

Drum Group 3 vas located in Top Camp, north of the parking area at

the terninus of the access road, Approximately 150 drums made up this

group. The drum vere arranged in rows and stacked upon other buried

drums. The condition of the drums ranged from poor to fair. No stained

soil or stressed vegetation-vas observed. One cosposi te soil sample

vas collected from among the drums (025SL).

The Top camp area also contained 63 scattered drums. The field

team noted these drums in a stream adjacent to Drum Groups 1 and 2, in

an area dovngradient from the parking area, and partially buried in the

p a a h e composite soil sample vas collected from ¶oils dovn-

gradient of the pmrking area (030SL). A triplicate sadiamt grab sample

(026S0, 027S0, 02BSD) was collected from II streu bed crossing the

southwest side of the parking area. These sediatnts produced a distinct

sheen vhen disturbed.

4.4.3.2 5..plf- at Other Loutiona

In addition to the drum group samples, the field team collected a

water sample (029VA) and a composite sediment sample (024SD) at Top

Camp. The vater sample vas collected downgradient of the parking area

in the stream that crossed the southvest side of the parking area. This

sample location was several meters downstream of samples 02650, 027SD,

and 028SD.

The sediment sample, 02450, vas collected in a poorly drained area

dovngradient of the parking area. A sheen and layer of rust vere noted

on this sample.

inforution is included for each:

o A physical description,

o Background information,

o A listing of contuiiunts,

o A discussion of analytical results.

A total of 33 samples vere collected from September 7 through

September 10, 1991: 17 surface soil samples, six drainage sediment

samples, five vatec samples, and five drum product samples. Included in

this total vere one background surface soil sample, one PA and one W

rinsate sample, one QA and one OC soil samples, and one 0 A and one QC

sedinent sample, vhlch vere collected and submitted to the project and

QA laboratories.

The soil, sediment, drum, and vater samples vere analyzed for some

or all of the folloving paraneters: Fuel ID and quantification (EPA 8015

modified), RCRA metals (EPA 6000/7000 series), PCBs (EPA B N O ) ,

and PARS (EPA 8100).

Contaninant concentrations are discussed as significantly elevated

in this section if they are 10 times the detected background level or 10

times the detection limit for analytes not detected in the background

saple. This level vas arbitrarily selected as being indicative'of

analyte concentrations that are not naturally occurring.

5.2.1 lhta Validation

The analytical data vere revieved by the CBHPD Haterials Laboratory

and this reviev (w) is included u Appcndix A. The COM is a

discussion of the data validation based on QC criteria for the folloving

U / P C controls: aurr-atm spihm; mtrix splkeIutrix spike duplicates;

laboratory duplicmtm and b l h ; blind duplicates~ rinsite blankst

assessing coataminant levels at A.chitlu Islud. A 1 1 Fuel ID .ad PCB,

a d m r t ?h a d metals data w r e conmidared acceptable by m. The follwing results for silver, chromium, and PAB u u l y s u are considered questiomble or estimated.

o The silver concentrations in oil should be considered a low tstimte due to low matrix spike recoveries;

o P M coacentrations of samples 9136WCE009St and 9136AUCB018SL are questionable due to lov surrogate recoverias; and

o The silver and chromium concentrations in soil samples reported by the M laboratory should be considered estimated due to lov surrogate recoveries.

All positive values for the data summarized above flagged "J"

indicate an analyte is present but the quantitation is questionable.

Negative results flagged "UJn indicate that the value is estimated and

that false negatives may exist in the data.

The method detection limits for many soil and sediment samples are

elevated due . . to sanple dilutions as a result of matrix interferences

and, in some cases, low sanple percent solids content. The project

samples vere analyzed by Columbia Analytical Services, IRC., Kelso,

Vashington. ~ h ; QA samples were analyzed by ABDL, Inc. , Mount Vernon, Illinois.

5.2.1.1 Organic Data

The organic parameters analyzed for vere Fuel ID, PCBs, and'PABs.

All organic data were deemed acceptable by the CWPD vith the exception

of saaples 9136AWCR009SL and 9136AHCH018SL as mentioned previously.

Results have been flagged J or UJ accordingly.

5.2.1.2 Inorgauic kt.

The inorganic parameters an8lyzed for vere the follovinp TAL

metals I arsenic, bariun, cadmium, chromium, led, mercury, selenium,

and silver. All metals data vere d o u d acceptable by the CEWO vith

the exception of the silver rasults for oil suples md the silver md

chromium ruults reported for soil suplcs by the M laboratory. Thame

results vere flagged J or UJ.

5.2.2 Iabrstory Cmtrolm

Sveral tuples vere analyzed after the recownded holdirq ti-;

hovever, CEWPD states that the data q u l i t y vas not affected since

suples vere preserved at 4' C during storage.

. 5.2.2.1 Trip E h n b

No trip blanks vere submitted for analysis.

5.2.2.2 S.rpliag Epui-t Bknt.

Sanpling equipment blanks, or rinsaie samples, are collected to

determine potential contamination of samples resulting from samples

collection devices (augers, mixing lmvls, stainless steel trovels,

etc.). An aqueous rinsate blank vas prepared by rinsing the stainless

steel soil sampling trove1 and bovl vith organic-free water and col-

lecting the resulting liquid. A duplicate rinsate was also collected

and submitted to the OA laboratory for analysis. The rinsate was

analyzed for fie1 ID, metals, PCBs, and PABs. Analytical results for

the rinsate samples vere below detection limits with the exception of

3.9 vg/L of lead detected in the QA duplicate sample. This level is

near the detection limit of 2 vg/L for lead in, the project-analyzed

rinsate sanple and is considered conparable.

5.2.2.3 Field Duplicates

Of the 33 total soil, sediment, drum, and vater saaples collected,

one blind duplicate soil and one blind duplicate sediment samples vere

collected and submitted to the project laboratory. Also included in

this total vere one PA soil sanple, one 0A sedi.ent sample, and one (ld

rinsatr ample, vhich vere collected and submittad to the QA Laboratory

for mlysis. One OA/OC set of duplicates vss collected out of I? soil

suplea md one M/QC set of dup1icat.s was collected out of six

sdi-t smmplu. One vater 0 A duplicate (I rinsate sample) v u

coll*ctd. Wa duplicate drum suplea or surface water suplss wore

col1ret.d. Since 10% is tb. rate specified in th. Chemical Data

Acquisition P l a n (CDAP) for duplicate sets, an insufficiant number of

duplicrtes vu collected for soil, surface -t8r, and drum aup1.s for

th i s project. All blind dupliate data agrue, vith the exception of the

f ollwing:

o The project-blind duplicate PAE data for suplts 9 1 3 6 ~ 0 0 8 S L lad 9136AMCE009SL d i s y r u vith the M data for duplicate supla 9136Ai(CB010SL. CHllW considers the project data questionable, as high lwels of fuel vere also detected in the duplicates, which indicates the presence of P r n .

o The project-blind duplicate PAE reaults for samples 9137MCR026SD and 9137AHaH)27SD do not agree vf th the PA laboratory data for sample 9137AnW028SD.' CEtlPD considers the project data questiomble for the reasons stated above.

5.3 A U A L ~ C A L BBsars

5.3.1 3nckgrmwd Conditions

One background surface soil sample (9136Ai4CR021SL) vas collected at

Amchitka Island. The sample was collected upgradient of the Bird Cape

area in apparently undisturbed tundra. See Table 5-2 for a summary of

analytical results for this sample. The project laboratory reported a

hydrocarbon concentration of 1,310 mg/kg, quantitated as oil for this

sample. The sample matrix consisted of moist soil dominated by peat and

organic naterial with a laboratory-reported solids content of 34X.

E & E believes the compounds identified are naturally occurring organics

that produce a chromatogran vithin the range of the oil standard

(hydraulic oil) used by the project laboratory to quantify petroleum

hydrocarbons. Not enough information vas provided by the Fuel ID

analysis (Hodified 8015) to accurately identify the compounds that were

quantitated as oil by the project laboratory. The background sample

trace chromatograph and the oil standard chromatograph are included as

Appendix C. Additional analysis by mass spectroscopy is suggested. All

other detected analytes fall vithin normal concentration ranges for

soils in the vestern United States.

5.3.2 W c..P he h o e up area includes the entire southeastern end of the

i3l-d (am Pilure 2-1). S-pling occurred at the asbestos disposal

area a d at a raported petroleum a n p along a roadvay adjacent to

Constmtine Earbor.

The asbestos disposal area is a gently sloped landfill cover in^ an area of approxiutely 2 acres. The landfill v u apparmtly created

during the 19116 renova1 action. At the dovngradient end of the h d f ill vrs a pool of vrter with 4 visible sheen. Oil (290 w/L) vas detected

in 4 water suple (033VA) coll*ctcd at this location. A collocated

sediment sample (032SD) also contained oil (490 mg/lrg). These con-

centrations indicate the leaching of POL products froll the landfill.

Other malytes detected at this location vere arsenic, barium, chromium,

and lead. See Table 5-1 for saaple analyt~ical results. The seep near

Constantine Harbor (Figure 2-1) consisted of a 3-foot by 2-foot rust-

colored stain on an enbankwnt above a drainage ditch. The stain

emanated from what appeared to be a forner underground POL pipeline.

Upgradient of the pipeline vas a forner POL tank farn. A sediment

sample (031SD) collected at this location contained oil at a con-

centration of 1,290 mglkg. Other analytes detected at lov levels vere

arsenic, barium, chromium, and lead.

5.3.3 Bird cape Area

The Bird Cape area is-located at the northern end of Amchitka

Island (Figure 2-2). Major sampling locations at Bird Cape vere drum

groups, a debris pile, and a stream. The Bird Cape area was reportedly

MCBITKlr ISLWD/car 5-5

recycled oaper

used as an advance warning outpost during World War 11. Facilities

included housing, refrigeration, and mtor pool areas.

Contaminants detected at concentrations at least 10 times their

background c~ncentratlons included diesel fuel, oil, PM, barium,

chromium, and lead. See Table 5-2 for a summary of Bird Cape area

sanple analytical results.

D- sample OllDR. collected at Drum Group 2, vas reported by the

project laboratory to contain 1,010,000 mg/kg of diesel fuel. Readings

in excess of 100% are possible when the results are extrapolated from

the analysis of a greatly diluted sample. This value is vithin the

required QC criteria and is considered valid. Relatively high levels

(5,400 to 270,000 -/kg) of diesel fuel vere reported in soil samples

usociattd with Drum Groups 2, 3, 4, and 6. These findings indicate

th.t POL drum at the drum groups have released diemel to the

surrounding soil.

Drcn product supler collected from Drum Grwpa 1, 5, and 7

containd oil a t conctntratioru ranging from 1,030,000 to 1,270,000

-/kg. mile they wain indicate concantratlona in excess of lWX, the

data are sufficiently reliable for product identification. Relatively

high levels of oil vtre reportd for soil suples collectd from Drum

Groups 1, 5, atid 7 (22,000, 320,000, m d 47,000 ng/lrg in samples 005SL,

015SL, and 013SL, respectively). These findings indicate that POL drura

at drua groups have released oil to the surrounding soil.

Significantly elevated concentrations (2.3 to 2,870 =/kg) of P M s

vere encountered in soil samples from Drum Groups 3, 4, 5, 6, and 7.

These PAB concentrations are consistent with the presence of diesel fuel

and oil found in drum product and soil samples at the same locations.

Individual compounds reported at high concentrations in soil vere

chrysene at Drum Group 4 in sample 014SL (2,870 mg/kg), and naphthalene

at Drum Group 3, in sample OlDSL (1,100 ag/kg). See Table 5-2 for a

sumrc,acy of sample analytical results.

Lead was detected at elevated levels in soil sample 007% (102

%/kg), and in soil sample 014SL (224 mg/kg), collected at Drum Groups 2

and 4, respectively. These levels may be high enough to qualify the

soil as a RCRA vaste. In addition, soil samples DO7SL and OlOSL con-

tained chromium at levels of 37 and 39 mg/kg, respectively. No other

soil samples contained metals at concentrations significantly above

background levels. NO contaminants vere present above detection limits in the water

sample collected at the Bird Cape area (017VA).

5.3.4 Top Carp Area

The Top Canp area is located on a ridge at the northern end of

hchitlu Island (Figure 2-3). Top Canp vas established during World Uar

I1 and w a s also utiliaed by the AEC during underground nuclear testing.

Samples vere collected at three drum groups, a parking area, and in

a v e t l d downgradient of the parking area. Contuimnts detected at

concentrations at 1-t 10 times background concentrations included

dieral fuel, oil, P M , and lud. See Table 5-3 for a sriury of Top

camp a r m supla uulytical results.

!jamplea associatad vith Drum Groups 1, 2, m d 3 (022SL, 023SL, and

025SL) vere found to contain oil and diesel fuel. Oil concentrations in

there suplas ran& from 300 -/kg to 570 mg/kg. Diajel fuml v u fwnd

in sample 025SL, collecttd at Drum Group 3, at a concentration of 120

q/4. Sample 030SL, collactd from roil surrounding d r u u at the b u e

of the puking area, containd oil at a concentration of HO -/kg.

Diesel fuel v u all0 detactad in this suple at a concantration of M

-!kg. These concantrations are significantly belov the Alask4 Depart- m e n t of Environmental Conservation (Am)-specified.potcntid cleanup

level of 2,000 mg/kg (Am 1991). Diesel contaaination vaa also detected in sediment samples col-

lected in the parking area and the downgradient vetland. Triplicate

sediment sample 026SD, 027SD, 028SD, collected from a stream vithin the

parking area, contained diesel fuel at concentrations ranging from 5,000

to 11,000 ng/kg. Sample 026SD vas also reported to contain oil at a

concentration of 850 mgfkg. Sample 024SD contained diesel fuel (510

mglkg) and oil (310 &kg).

PAE compounds vere found in parking area sediments at concentra-

tions ranging from 4 to 910 mg/kg. The compounds detected are fre-

quently found in association vith diesel fuel contamination.

Lou levels of PAE vere reported in soil sanples 23SL and 030SL (0.2

mgflcg and 0.9 mg/kg, respectively). These samples also contained diesel

fuel and oil.

Designation of contuinurts of concern for luchitlu Islrnd are

basad on the folloving criteriat

o For petroleum hydrocarbons in soils, concmntrations utcrding the leut rmmtrictive cleanup lwel rtipulatd by ADEC (2,000 -/kg) shall be coasidmrd a contuilunt of coacern. ADEC vill be co~ulted concerning moil c l u n u p levels prior to clemup activitics~

o P H s are constitwnts coroaly umociatmd vith fuela. For P a in roil, concmtrations acmadi~ 10 tiws the background d y t e concmtrations, or 10 tius tbr detsttion limit of undetected background a~lytes, rW1 be conridered r contuiluat of concern. This is M arbitrarily selected level that identifies thut cons ti tuents as not mturrlly occurring and potentially in need of further study;

o For heavy metals in soil, target metal concentrations exceeding 20 times their respective TCLP limits shall be considered a contminmt of concern. This action level is b e d on a 20:l dilution employed in the TCLP method, and is the level required to detect a quantity above the regulatory limit, assuming 100% is extracted/leached during the procedure;

o For petroleum hydrocarbons and Pbes in vater, any detected concentration shall be a contaminant of concern; and

o For heavy metals in vater, concentrations exceeding federal maxiaum contaminant levels (t4CL.s) for drinking vater shall be a contaminant of concern.

It should be noted that these criteria are not proposed action

levels for cleanup or remediation. The criteria represent contaminant

concentrations that should be further evaluated vfth regard to off-site

migration, human or vildlife exposure, and the consequent need for

cleanup, Based on the criteria listed above, Table 6-1 summarizes the

contaminants of concern and the affected areas at Amchitka Island. Of the analytes detected at Anchitka Island, the following occur at

sufficient concentrations to be considered contaminants of concern:

diesel fuel (5,000 to 270,000 mg/kg); oil (22,000 to 320,000 mg/kg);

naphthalene (1,100 mg/kg); acenaphthylene (1.8 to 370 mg/kg);

acenaphthent (8 to 370 ~ l k g ) ; fluorene (260 to 370 &kg); phenanthrene

(4 to 170 mg/kg); fluoranthene (27 to 31 ~ ~ ' l r g ) ; benzo(a)anthracene (199

to 237 agfkg); chrysane (63 to 2,870 uig/kg); bmzo(b+k)fluormth.nt (61

to 293 ~ f h ) ; benzo(a)pyrtne (372 nglb); and l e d (102 to 224 *91kg),

These compouads/eluenta are further evaluated in the follwfng sub-

section. and will be addressed in the hchitkn Island Remedial

Altermtivu W r t .

6.1.2 C a a t u h m t Utsmctari8tiu Th. follwing paragraphs suuarix. ch8racteristica of the con-

tuinmt: lirtad in section 6.1.1. Both pntrolew c o n t u i ~ n t s (dimsnl

fuel, oil) have similar ttwport cbarmcturistics. Th-e hi& molecular

might conatitwnts are likely to adsorb to soils, particularly thore

vith 4 high organic content. Although the mter solubility of diead

fuel and oil is minimal, migration of POLS via mter could be expected

to affect surface water bodies and, potentially, groundvater.

Plle compounds are persistent in the environment and are strongly

adsorbed to soils, particularly those hnving hish organic content. They

are also readily assimilated by plants, thus entering the food chain.

In water, these co=pounds tend to concentrate in sediments and aquatic

invertebrates. Some P u s are carcinogenic in mmals.

The mobility of lead in soils is variable, depending on the nature

of the soil. It generally bonds to organic naterial in soils. Conse-

quently, lead in soils is not easily assimilated by plants. Elemental

lead is highly soluble in water, hovever, and thus is quite mobile in

surface and groundvater.

6.2

Potential receptors of greatest concern include the approximately

160 residents of hchitka Island in addition to the nine threatened or

endangered species in the vicinity. These include eight endangered

species of whale and one threatened avian species, the Aleutian Canada

goose. Karine species such as vhales may be at risk mostly from lead,

vhich is mobile in surface vater. The Aleutian Canada goose and other

terrestrial species may be at risk for exposure to lead in the surface

vater and PAHs in plant and invertebrate f w d items.

Human and animal populations may be potentially exposed via air,

soil, groundvater, and surface vater. These pathways are discussed in

the folloving section.

6.3 m- PATEVATS

6.3.1 Air hthrq

There bvt been no known releases of contaminants to the air frol

any of the rltmg. nobility of the contuinmts by volatilization to the

atrospficre is limited by several factors; the adsorption to fine-

grained uterid and silts, the confinfnf effects of overlying ground

cover ( i .e . , vwtation), and the confining effects of a frozen surface

layer duriw framing periods.

Soils on Amchitka Island arc primarily volcanic and contain luge amounts of organic matter, greatly increasing the adsorption of orgmic

cwpouads. The island is almost completely dominated by gruaes during

the surer months, and a freezing layer of snovkll covers the island

' during the vinter months. Additionally, the island's mist climate and

lush vegetative layer leaves little chance for the buildup of dusts and

the inhalation of contaminated airborne particulates. Because of these

conditions and the fact that POL products found on hchitka have been

veathering for more than 40 years, all volatile constituents may be

assumed to have evaporated or to be vell confined prior to the present

time.

6.3.2 Soil Pathvay

There are five potential exposure routes by vhich humans and

animals inhabiting Amchitka Island may cone in contact with contaminated

soils. These include:

o Ingestion of soil contaminants;

o Inhalation of contaminated particulates;

o Dermal adsorption of soil contaminants;

o Ingestion of vegetation grovn in contaminated soil; and

o The ingestion of contaninated sediment underlying or suspended in surface vater.

The contaminated area closest to island residents is the ~sbestos

disposal area located approxiutely 2 miles from bate cup. Duc to this

distmce frm residential housing, residents do not nornlly psrticipta

in activitias on or n u r arau of soil contuination and therefore have lov risk pot.nti.1 for exposure to rite contuinmts. Wildlife, hov-

ever, n y have a grnter potmtial for coming into contact vith site

contaminants particularly through iwrtion of v-tation grovn in

comtamir18t.d soil, .nd ingertion of contaminated s e d i m t or inver- tmbratms. This is particularly appliubla to the Bird kp. and Top Caap

a n u , durn-elevated PAE concentrations occur in sedimnts.

6.3.3 G m m u h t u htbmy Groundvater is not a potential pathvay for pollutant expoaura from

the u r a s of contdrution because drinking vater for domestic use is

obtained from surface impoundamto aad springs. Although groundmtar is

not utilized as a drinking vater source on Amchitka Island, the poten-

tial exists for migration of contaninants to groundwater. Groundwater

could also be expected to transport contaminants from waste source a r m s

to springs, surface ponds, or the marine environment.

6.3.4 Surface Water Pethvay

Surface vater appears to be the pathvay of greatest concern. Dur-

ing the E b B inspection POL products released to surface vater vere discovered in three separate areas on the island. The first area vas

discovered adjacent to Bird Cape Drum Group 5 (Figure 4-2 ) , vhere POLS

vere observed flowing into an intermittent stream that eventually flovs

into a 10- by 20-foot-vide pond. Surface vater in the form of a small

flowing stream exits the pond in a vesterly direction and empties into

the Bering Sea (see Plgure 2-2). E b E field tean members collected a

soil snaple from this area upgradient of its release into the stream.

Sample analytical results indicate the release contains 320,000 mg/kg of

oil as well as arsenic, barium, chromium, lead, and PAHs. Surface vater

vas sampled at the stream exiting the pond; however, contamination vas

not present above detection limit at this point.

It is possible that the pond itself may support freshvater fish and

birds that nay be exposed to fuels and PAEs accumulating in sediments

and plants or lead dissolved in surface vater. Six different species of

fish and up to 131 species of birds have been recorded on or near

Aachitlca Island. Should contaminants migrate the approximately 1,000

feet to the Bering Sea via surface vater, the concentrations vould

likely be such lover than those found in the pond due to dispersion in

surface vater and dilution with occur vater. Marine -1s such as

the eight species of endangered vhles that inhabit the coastal vatrrs

m y also be axposed via thir pathvay, although it is unllkmly that POL

conta=inmts would reach the coast in sufficient conc.ntrations to pore

a substantial risk to urine life.

In the aecond arm, located immediately dovn#rrdiant m s t of the

asbestos disposal area, a POL sheen vas observed on a standing pool of

vater. Yattr and sediment smples vere taken from this location and

sample analytical results indicated 290 ug/L of oil in vater and 490

' ng/kg of oil in sediments as vell as several heavy metals, including barium, cadmium, chromium, arsenic, and lead. Eovever, the concentra-

tions of these amiytes vere belov the applicable action levels. There

vas no surface vater observed exiting the pool.

The third area is located in a vetland dovngradient of the Top Camp

area. The Top Camp area 1s located on a ridge at the northern end of

Amchitka Island (see Figure 2-3). Samples collected from sediments in

the parking area contained diesel at concentrations of 5,000 to 11,000

mg1k.g. PAB concentrations ranging from I to 910 mg/kg were also found

in these sediments. Both the diesel and PAR concentrations are high

enough to pose a threat to human health and the environment. The pre-

sence of these contaminants in sediments makes them readily available

for migration via surface vater. Some migration has already occurred,

as indicated by diesel contamination found in a dovngradient wetland

nrhn nnd rn.innnw.m

sample (OZ4SD). Surface water in the vetland area flovs intermittently

in a southerly direction and evmtrially enters a l a k e approximately 1

mile avay.

7.1 9 U W Y

Three mrws on Amchitka Island vere in\r.stlgated by E 6 B during

September 1991. ?be three are-, Bird Cape, Top C..p, and Base Cm$,

vare identified through backround research as potential sources of petroleum m d haz*rdous rubatmces contamination, Surface soil,

sedimt, drum, snd vater suplea m r e collectrd at there 4r.u to

chrarterixe the p r u m c e and nature of contaminant sources and to

deterrim tbe extant of off-rite contaminant migration.

A total of 33 field r u p l u includiw one background mample, tuo

rats of WOC duplicate s u p l u plus OM rimate sad it# duplicate were

collected from the three areas on hchitlu Islmd. halyticml reaults

of the r u p l u indicated the preaence of petroleum, P M , and l e d

contamination at all three areas investigated. Thc ambestos disposal

area and nearby 8eep at B M ~ Caap contained elevated concentrations of

oil. Drums at Bird Cape have leaked and contaminated surrounding

surface soil and surface water vith diesel fuel, oil, lead, and PABs.

Drums at Top Camp have also leaked diesel fuel and oil into surface

soils. Righ diesel fuel and P M concentrations at the Top W p parking

area and in a downgradient vetland area vere detected.

Contaninants of concern proposed for Anchitka Island include

diesel fuel and oil petroleum hydrocarbons, 10 PAB compounds, and lead.

Contaminants of concern Were detected at all three areas investigated.

Surface water is the most likely migration pathvay through vhich con-

taninant exposure to humans or vildlife could occur.

Chromium may potentially be a contminant of concern as vell.

Chromium vas detected at levels above background, although the detected

levels of chromium did not exceed the criterion for selection as

contaminants of concern. This criterion, as discussed in Section 6.1.1,

is based on a 20-fold dilution used in the TCLP extraction procedure and

subsequent extrapolation of the regulatory limits.

7.2 LXRKWSIOtlS

Results of the hchitka Island investigation indicate that chemical

cont~inrtion from petroleum and hazardous substances is present at

identified potential contuinant source areas. Bird Cape appears to be

the area containing the most significant nunber and concentration of

contuinmts. All of the contaminants of concern identified for this

project were detected at Bird Cap.. Bass C u p and Top are con-

sidered to ba less of a thrut to huun health or the envirommt based on the awbmr md type a d concmtration of contulnmts detectd in

them a r w . only the areu of Amhitka Islmd specifically addressed in this

report were invwtipted. Conclusions m d recommhtionr for a11

coatuilunta refer only to thue a r w . A l t h o ~ h tha invutigatiw vas

b a i r n to d d r u r the potentially mo4t cont.limted a r w of each island, it ia pomaibla that other areu not inveatig8t.d also contain

contuimntr at levala of concern.

A. mentioned in Section 4, w s t of the drums encountered during the investigation Vera in poor condition. This observrtion md the yyc of

. contaminated debris suggests that the w s t significant contaminant

releases f r m these materials have occurred in the past. eresent coo-

ditionr observed during the field investigation and fror analytical data

are likely representative of a steady-state situation after many years

of debris weathering, contaminant releases, and natural ertviromental

degradation. The need for cleanup and/or remediation of contamination

on Anchitka Island should be evaluated with regard to enviromental

damage from heavy equipment, the relative concentrations and toxicity,

nobility, and persistence of identified contaminants of concern, and the

quantity of potential contaminant receptors that could be exposed to

on-site contantinants. These issues will be evaluated in the Amchitka

Island Remedial Alternatives Report.

g. -: All met method requirements.

h . -: Hodif ied 8015 analysis of sample -029Yh was done one day nftrr the w r i m m allowed HT. Data are not severely affected as samples uere mtored in the dark at I C. PM sample -032 was reanalyzed 16 days after the r e c o m n d e d HT, due to Internal OC failure. PAH ranplea Ol'IYh a d -019WA were recclved at the project lrbo~atory tuo days after

the r e c o m n d e d AT. Data are not severely affected doc t n a feu days of RT expiration when salrples at* well preserved.

i . Qyg-tht Pr- I : A11 data are acceptable except silver data in 011, where MS recovery uas 40-percent.

1 . WALUATIOt4 OFTIIl8QALhBORA?ORY'S DATA: Laboratory blanks, aethad detection limits, calibration, surrogate recoveries, HS, MSD, HT, control recoveries and RPDos met method rcqairemnts except for recovery of silver in soil was zero and chromium w s 36-percent. These analytes my not have bacn completely recovered if present at low levels in the sol1 m t r i x . The laboratory control recoveries of these actals were vlthin QC limits, vhich indicates poor recoveries wcre due to natrix effect. THt HS and HSD of PCB's vere above upper advisory limits. As no PCB's were detected, ttiglber recoveries did not affect the data.

8 . QMQC COMPARISONS: QMQC comparisons are shorn in Tables I1 and 1 1 1 . All data agree except PAM data in Tables 11-2 and 111-2 and lead in Table 111-3, where the project data appears questionable as s?ll/sedjnent samples wcre contaminated with up to 24000 ppm of dlesel, indicating the possible presence of PAH's in the samples. Up to four PAH1s, ranging in concentration from 110 through 1100 ppm uere found in the PA samples, which a generally expected in soi l/scdiment samples high1 y contaminaf ed ui th fuel. The aforementioned soll/sediment OA data are acceptable and can be substituted for the project data where applicable. The Iead discrepancy in Table 111-3 1s probably due to non-identical distribution of lead in sediments.

Environmental Evaluation and Remediation Alternatives Great Sitkin, Kiska, Attu, and Amchitka Islands, Alaska

1.0 INTRODUCTION

The U.S. Department of Defense Senate Appropriations Bill for 1991 included authorization and funding to the Corps of Engineers to provide Congress with an assassment of environment damage and remediation requiremanto for potential environmantal hazards resulting from past military activity on Great Sitkin, Kiska, Attu, and Amchitka Islands. These island. are located in the Aleutian Island chain in Alaska.

Graat Sitkin Island: Tha U.S. Navy used approximataly 700 acre. at Sand Bay as an advance fumling station from 1943 to 1945. In 1957 the Navy obtained a permit to use 9310 acres for a temporary pmtrolaum storage facility. The permit axpired in 1962. The island is currantly under the jurisdiction of the U.S. Fish and Wildlife Senice.

Kiska Island was occupiad by the Japanese in 1942 and 1943. The U.S. Army and Navy used thm 5850 acra site am a protective garrison from 1943 to 1945. Tha Navy had jurisdiction of thm site from 1949 to 1955. Use, if any, during this time is unknown. Reports indicate that live ordnance is scattered on the island. The island is currently under the jurisdiction of the U.S. Fish and Wildlife Service.

Attu Island was occupied by the Japanese from 1942 to 1943. The U.S. Army and Air Force utilized the 8 2 , 4 0 0 acre island until 1950. Reports indicate that live ordnance is scattered on the island. The island is currently under the jurisdiction of the U.S. Fish and Wildlife Service. There is a small Coast Guard LORAN station orb the island.

Amchitka Island was utilized by the U.S. Army and Air Force periodically from 1943 until 1961. The 71,000 acre site was utilized as the Amchitka Army Air Base. In 1965, the Atomic Energy Commfssion used the island for underground nuclear tests and studies until 1973. Reports ihdicate that live ordnance is scattered on the island. The island is currently under the jurisdiction of the U . S . Fish and Wildlife Service.

2.0 PROJECT OBJECTIVES AND SCOPE

The primary objectives of this project are as follows:

o Determine the presence, approximate quantity, and nature of HTW and POL at each island;

o Determine the pesence and/or the extent (where possible) of contaminant migration froa HTW/POL disposal areas;

o identify potential human and environmental contaminant receptors ;

o Conduct a reconnaissance leva1 inventory of anthropogenic debris of DoD origin on each island; and

o Provida appropriatm claan-up/remediation options for areas of concern at aach island.
