Re: Consent Agreement and OrderDocket No. III-86-12-DCScovill Site at Montross, Virginia

Dear Walter:

The purpose of this letter is to transmit soil data which we obtainedsubsequent to our September 19 letter report to you. In accordance with ourrecommendation in that letter, ICF Technology resampled soils in the old pondin order to verify the presence of elevated concentrations of lead that hadbeen reported in an initial sample; viz., TCLP of the 0-6 inch compositesample from the west side of the old pond bottom (collected on August 26) wasreported to have a TCLP concentration of lead of 3,200 ug/1.

On October 5, ICF Technology collected a composite sample from the westside of the old pond using a hand auger. Soils were taken from the same fivegrid units used on August 26 and from locations as close as possible to theoriginal auger holes. The sample was then placed in an ice filled cooler andsubmitted to Versar for TCLP analysis. As shown in the attached laboratorydata report, no lead was detected in the October 5 sample.

This resampling result, in conjunction with the fact that no otherelevated concentrations of lead were detected in the old pond, indicate to usthat lead is not a problem in the old pond soils. The result confirms oursuspicions that the 3,200 ug/1 concentration was an anomaly, perhaps occurringduring laboratory analysis. As a result, no additional soil removal isproposed for the old pond prior to backfilling.

I am requesting your approval of this decision as soon as possible as weintend to proceed with earthwork at the site sometime in the next week.

Sincerely yours,

Gary N. DietrichSenior Vice President

Dear Walter,

In my letter of September 19, 1988, I reported and assessedthe results of the soil samples taken from the ponds at thereferenced site after the sludge and underlying soils had beenremoved from those ponds pursuant to the approved Phase IIAbatement Plan. In that letter, I concluded that the followingadditional soils should be removed from three of the six ponds:

• 6 inches from the floor of the new pond,

• 6 inches from the north, east and south sides of thesoutheast pond, and

• 12 inches from the bottom and 6 inches from the east,south and west sides of the northwest pond.

During the week of November 7, these additional soils wereremoved from the three ponds and sent to landfill disposal at theChemical Waste Management Facility at Emelle, Alabama. OnNovember 11, the new soil surfaces created by this additionalsoil removal were sampled in accordance with the procedures setforth in the Phase II Abatement Plan. On November 29, wereceived the results of the total and TCLP metal analyses ofthese samples and, on December 7, we received the total cyanideanalyses of these samples.

The purposes of this letter are to (1) officially transmit

flR300208

ICFTECHNOLOGY INCORPORATED

copies of the laboratory reports on the November 11 sampling\ results (copies were unofficially sent to you on December 12),! (2) present my assessment of the November 11 sampling results as

well as my assessment of the overall soil sampling results, (3)recommend additional sampling of cyanide concentrations in the

; new and northwest ponds, (4) describe procedures that we willtake to prevent erosion of the backfilled ponds when this task isperformed, and (5) request an extension of time for completion of

I the Phase II abatement work. As such, this letter reduces towriting the several telephone conversations we have had over thepast month and documents the agreements we have reached in thoseconversations.

Assessment of the November 11 Sampling Results

Tables 1 and 2 provide comparisons of the November 11sampling results with the previous sampling results for the newsoil surfaces created by the additional soil removal. Based onthe objectives of the additional soil removal (see Table 5 of mySeptember 19 letter), these tables reveal the following:

New Pond

• The total concentrations of all of the parametersdecreased.

• The total cyanide concentration on the floor of thepond was not reduced below 10 mg/kg as had beendesired. However, the average total cyanideconcentration for the pond was brought down to 12.1mg/kg (derived from the results reported on Table 3)which is only slightly greater than the 10 mg/kg goal.

• The TCLP concentrations for the several metals were notsignificantly reduced as had been desired (in fact, theTCLP concentrations for chromium and copper increased).

Southeast Pond

• The total concentrations of all of the parametersdecreased significantly.

• The total cyanide concentrations on the north, east andsouth sides of the pond were reduced below 10 mg/kg ashad been desired. This reduced the average totalcyanide concentration for the pond to 3.5 mg/kg


(derived from the results reported on Table 3) which isless than the 10 mg/kg goal.

• The TCLP concentrations for copper on the north, eastand south sides of the pond were reduced below 8,200mg/1 as had been desired. This reduced the averageTCLP concentration for the pond to 2,479 mg/1 (derivedfrom the results reported on Table 4) which is lessthan the 8,200 mg/1 goal.

• The TCLP concentrations for chromium and lead on theeast side of the pond were significantly reduced as hadbeen desired.

• The TCLP concentrations for lead on the north and southsides of the pond increased significantly, even thoughthe respective total lead concentrations decreased.

Northwest Pond

• The total concentrations of all but two of theparameters decreased and, in most cases, decreasedsignificantly.

• The total cyanide concentrations were significantlyreduced, except on the east side where theconcentration was increased slightly. However, exceptfor the south side, these concentrations were notreduced below 10 mg/kg as had been desired.Nevertheless, the average total cyanide concentrationfor the pond was reduced to 12.5 mg/kg (derived fromthe results reported on Table 3) which is only slightlyhigher than the 10 mg/kg goal.

• The average total concentration of chromium (16.6mg/kg, as derived from the results reported on Table 3)was almost reduced below the upper bound of thebackground range (15.3 mg/kg) as had been desired.

• The average TCLP concentration of chromium (47 mg/1, asderived from the results reported on Table 4) wasreduced below the primary drinking water standard forchromium (50 mg/1) as had been desired.

• The TCLP concentrations for lead on all of the newsurfaces of the pond increased significantly, even

4R3002


though the respective total lead concentrationsdecreased significantly.

• The TCLP concentrations for copper were significantlyreduced, except on the west side. This resulted in asignificant reduction in the average TCLP concentrationfor the pond (to 9,870 mg/1 as derived from the resultsreported on Table 4) but not to the 8,200 mg/1 goal.

In summary, except for the unexpected increases in TCLPconcentrations for lead and the failure to reach the cyanide goalof 10 mg/kg in the new and northwest ponds, the additionalremoval of soils from the three ponds achieved the desiredreductions in total and TCLP concentrations.

Assessment of Overall Sampling Results

Table 3 reports the total metal and cyanide concentrationsfor the pond surfaces as they currently exist following theadditional soil removal. Table 4 reports the TCLP concentrationsfor the pond surfaces as they currently exist following theadditional soil removal. Both tables list the previous samplingresults for surfaces from which additional soils were not removedand the November 11 sampling results for surfaces from whichadditional soils were removed.

An analysis of Table 3 reveals the following:

• The average total concentration of chromium in the soilsurfaces of each pond, except the northwest pond, iswithin the background range.

• The average total concentration of chromium in the soilsurfaces of the northwest pond is 16.6 mg/kg which isonly slightly outside of the upper bound of thebackground range (15.3 mg/kg).

• The overall average total concentration of chromium inthe soil surfaces of all of the ponds is 11.1 mg/kgwhich is well within the background range (8.7 to 15.3mg/kg).

• The average total concentration of lead in the soilsurfaces of each pond is below the background range.

AR3002H


• The overall average total concentration of lead in thesoil surfaces of all of the ponds is 5.7 mg/kg which iswell below the background range (8.5 to 12.1 mg/kg)

• The average total concentration of cyanide in the soilsurfaces of each pond, except the new and northwestponds, is within the goal of 10 mg/kg (described in myletter of September 19, 1988).

• The average total concentrations of cyanide in the soilsurfaces of the new and northwest ponds are 12.1 and12.4 mg/kg, respectively, and, therefore, are onlyslightly outside of the 10 mg/kg goal.

• The overall average total concentration of cyanide inthe soil surfaces of all of the ponds is 5.9 mg/kgwhich is well below the 10 mg/kg goal.

• The average total concentrations of copper and zinc inthe soil surfaces of all of the ponds are above thebackground range.

An analysis of Table 4 reveals the following:

• The average TCLP concentration of chromium in the soilsurfaces of each pond is below the drinking waterstandard for chromium.

• The overall average TCLP concentration of chromium inthe soil surfaces of all of the ponds is 25.4 mg/1which is well below the drinking water standard forchromium (50 mg/1).

• The average TCLP concentration of lead in the soilsurfaces of each pond, except the southeast andnorthwest ponds, is below the drinking water standardfor lead.

• The average TCLP concentrations of lead in the soilsurfaces of the southeast and northwest ponds are 135.4and 126.5 mg/1, respectively. Although theseconcentrations exceed the drinking water standard forlead (50 mg/1), they do not exceed the minimumdelisting criterion for lead (315.5 mg/1) that EPA usesto delist hazardous wastes.

• The overall average TCLP concentration of lead in the


soil surfaces of all of the ponds is 68 mg/1 which isonly slightly above the drinking water standard forlead (50 mg/1) and is well below EPA's delistingcriterion for lead (315.5 mg/1).

• The average TCLP concentration of copper in the soilsurfaces of each pond, except the northwest pond, iswithin the goal of 8,200 mg/1 (described in my letterof September 19, 1988).

• The average TCLP concentration of copper in the soilsurfaces of the northwest pond is 9,870 mg/1 and,therefore, is only slightly outside of the 8,200 mg/1goal.

• The overall average TCLP concentration of copper in thesoil surfaces of all of the ponds is 3,783 mg/1 whichis well below the 8,200 mg/1 goal.

• All of the average TCLP concentrations of cadmium,nickel and silver in the soil surfaces of the ponds arewell below the drinking water standard or healthadvisory for these constituents.

. In my opinion, the above assessment indicates that the soilsurfaces of the excavated ponds have been cleaned to acceptablelevels. Admittedly, total concentrations of cyanide, copper andzinc have not been brought down to background levels, but:

• the overall average total cyanide concentration hasbeen brought to less than 10 mg/kg, a level which isunlikely to permit releases to ground or surface waterswhich would cause exceedances of the 0.2 mg/1 drinkingwater standard or the 0.2 mg/1 ambient water qualitycriterion in these waters (see my September 19 letter);

• the total copper concentrations have been brought tolevels such that the overall average TCLP concentrationfor copper has been reduced to less than 8,200 mg/1, alevel which is unlikely to permit releases to groundwater which would cause exceedances of the 1,300 mg/1maximum concentration level goal for drinking water(see my September 19 letter); and

• there is no health-based standard to assess the zinclevels.

AR3002I3


The elevated TCLP concentrations of lead in several of thesamples taken from the southeast and northwest ponds on November11 are troubling, but the overall average TCLP concentration oflead is within an acceptable level as stated above. Given thatthe total concentrations of lead are below background levels, Isuspect that there are small pockets of soluble lead in thesepond soils which would b« very difficult to locate and remove andwould require the removal of a large volume of soil from theseponds if they were to be eliminated.

Notwithstanding these conclusions, I respect your concernabout the total cyanide concentrations remaining in the new andnorthwest ponds. To address this concern and conform with theagreement we have reached in our telephone conversations over thepast month, we will re-sample the new and northwest ponds fortotal cyanide to develop data which will enable us to make a moreinformed determination as to whether additional soil removal fromthese ponds will achieve the 10 mg/kg goal for this constituent.

Recommended Re-sampling of New and Northwest Ponds

We will take five, 2-feet deep core samples from randomlyselected locations on the bottom of the new pond, the bottom ofthe northwest pond, and each of the east and west sides of thenorthwest pond. We will divide each sample into four, 6-inchsub-samples. We will composite the five sub-samples from each ofthe same depths and surfaces and will have these composite sub-samples analyzed for total cyanide concentrations. This samplingand analysis plan will enable us to define the cyanideconcentrations at four depths for each of the four surfaces and,therefore, will enable us to determine whether additional soilremoval from these surfaces will be productive in reaching thetotal cyanide concentration goal of 10 mg/kg.

This sampling program is scheduled to be conducted onJanuary 12 and 13, and we expect to have analytical results byJanuary 23. I will report these results to you, together with myassessment of them and my recommendation on any additional soilremoval, as soon thereafter as possible. Let me note that wescheduled this sampling on three previous dates during the pastmonth but were unable to initiate the activity because of illnessof our sample team leader on one of the dates and because of poorweather conditions on each of the other two dates.


Procedures for Preventing Erosion of the Backfilled Ponds

Pursuant to our telephone conversation of several weeksback, I have commissioned one of our civil engineers to design afinal grading, erosion control and seeding plan to be followed inthe backfilling of the ponds. This plan is currently beingreviewed. When it is finalized, I will transmit it to Westonwith the direction that it be followed in the closure of theponds. Also, I will have one of our civil engineers at the siteduring the final closure activities to supervise compliance withthe plan.

Request for Extension of Time

The Phase II Abatement Plan anticipated completion ofclosure of the ponds by the end of November. Obviously, thisdate has not be met, principally because of the extra timerequired to schedule and remove the additional soils, to obtainthe analytical results from the November 11 sampling of soils,and to schedule the re-sampling described above. Thus, I amcompelled to request an extension of time to complete the closureof the ponds under the Phase II Abatement Plan.

I am presuming that we can reach agreement by the end ofthis month, based on the re-sampling results, as to whetheradditional soils should to be removed from the new and northwestponds. If it is agreed that additional soils are to be removed,we will endeavor to complete this work during February. However,inclement weather may delay completion of this work until mid-March and the initiation of backfilling of the ponds until thelatter half of March. If it is agreed that additional soils donot need to be removed from the two ponds, backfilling couldstart in February. However, if would be more practical to delaythis backfilling until late March to avoid winter erosion damageand to facilitate the establishment of a vegetative cover on thebackfilled area. Consequently, in either case, I propose that weschedule backfilling, grading and seeding of the pond area forthe period of mid-March to mid-April and that we allow another 45days for performance of this work in the event that unusual wetweather conditions interfere with this work. Therefore, Ipropose that the completion date for the Phase II Abatement workbe extended to May 31, 1989.

Conclusion———————By this letter, I request (1) your approval of the

AR3QG2I5


recommended re-sampling of the new and northwest ponds asdescribed above, and (2) your approval of the revised Phase IIAbatement completion date delineated above. I will be happy tofurther discuss these matters with you, if you have any questionsor problems.

Sincerely yours,

May 1, 1989

Mr. William SteutevilleProject ManagerU.S. Environmental ProtectionAgency, Region III



Dear Bill,

As I promised in my letter of January 11, 1989, to Dr.Walter Lee, we re-sampled the east and west sides and the bottomof the northwest pond and the bottom of the new pond for totalcyanide. The samples from the northwest pond were collected onJanuary 12 and the samples from the new pond were collected onJanuary 27. All samples were taken with a hand-advanced coringtube to obtain two-foot core samples. Five samples were takenfrom each of the four pond surfaces. Each of these samples wassubdivided into 6-inch sub-samples, and the respective sub-samples from each set of five samples were composited anddelivered the same day to Versar for analysis. The resultsreported by Versar are provided in the enclosure to this letter.

The analytical results from these samples are delineated inTable 1 together with the results previously obtained from hand-augered grab samples. Except for the east side of the northwestpond, the results indicate that above background levels (<0.54 to<0.58 mg/kg) of total cyanide exist throughout the soil column toa depth of two feet and very likely beyond two feet. Theseresults further indicate that concentrations of total cyanidegreater than 10 mg/kg exist throughout the soil column to a depthof 18 inches on the west side and bottom of the northwest pondand to a depth 24 inches or greater on the bottom of the newpond. Consequently, these results suggest that removal of soilscontaining greater thanOLO jrcg/kg of total cyanide would requireexcavation of at least l§~lnches of soil from the west side andbottom of the northwest pond and excavation of more than 24inches of soil from the bottom of the new pond. For reasonsstated later in this letter, we question the environmental need

4R300223

ICFTECHNOLOGV INCORPORVTED

for and cost effectiveness of such removal of soils.

On January 27, we also took a sample of the standingrainwater in the new pond and a composite sample of equal partsof the standing water in the northeast, northwest, southeast andsouthwest ponds (no standing water existed in the old pond).These samples were not filtered in the field or laboratory priorto analysis. They were submitted the same day to Versar foranalysis of cadmium, total chromium, copper, lead, nickel, zincand total cyanide. The results of these analyses are presentedin Table 2 and in the laboratory reports enclosed herewith.

The sample taken from the new pond was visibly quite clearand, therefore, appeared to contain a low concentration ofsuspended solids. Consequently, the analytical results from thissample probably, in large part, represent the dissolvedconcentrations of the constituents in the standing water of thenew pond and very likely approximate the concentrations of theconstituents in the groundwaters immediately below the pond priorto their dilution as they move downgradient.

The composite sample taken from the other four ponds wasvisibly very turbid and, therefore, appeared to contain a highconcentration of suspended solids. This turbidity resulted fromthat portion of the composite sample drawn from the southeastpond which, over the preceding two days, had received waterpumped from the new pond in order to enable sampling of thebottom of the new pond. This pumping had stirred up the soils inthe southeast pond, and this produced the turbidity observed inthe composite sample (the samples drawn from the other threeponds were visibly clear like the sample drawn from the newpond). Because the composite sample was not filtered, theanalytical results from this sample represent both the dissolvedand suspended concentrations of constituents in the sample and,therefore, do not represent the dissolved concentrations of theconstituents in the standing waters of the four ponds or thegroundwaters immediately below the ponds.

Table 3 presents the concentrations of total chromium,copper, lead, zinc, and total cyanide in the soils of the pondsas they currently exist following the removal of all sludge andcontaminated soils from the ponds. The footnotes of this tableexplain the sources of these data. Table 3 also presents theaverage concentrations of these constituents for each pond andfor all of the ponds combined. We believe that these averageconcentrations best describe the characteristics of the pondsoils that will be left in place if no additional soil is removed

it,r i tin MJLUIJ i i M.UK t-'»K \ i t.i>

and if the ponds are backfilled as described in the Phase IIAbatement Plan, dated October 9, 1987, which was approved by Dr.Walter Lee.

Attachment I presents worst-case estimates of the potentialhuman health impacts of the current constituent concentrations inthe pond soils and the assumed concentrations of theseconstituents in the groundwaters underlying the pond area. Theseestimates are provided to demonstrate that additional removal ofsoil for the ponds is not necessary to protect human health.

The information presented in Table 3 and Attachment I enablethe following conclusions with respect to each constituent:

Chromium Table 3 shows that the average total chromiumconcentrations in the soils of each of the excavated ponds,except the northwest pond, and of all of the ponds combinedare within the range of background concentrations. Theaverage soil concentration in the soils of the northwestpond is only slightly above the background range.Therefore, these results indicate that total chromiumconcentrations have been substantially reduced to backgroundlevels and unlikely can be further reduced with additionalsoil excavation. The estimates of health impacts presentedin Attachment I show that the concentrations of totalchromium in the excavated soils of the pond area and in thegroundwaters underlying the pond area do not pose a threatof adverse impact to human health.

Copper Table 3 shows that the average copper concentrationsin the soils of the excavated ponds are above the range ofbackground concentrations. However, the estimates of healthimpacts presented in Attachment I show that theseconcentrations and the assumed concentrations of copper inthe underlying groundwaters do not pose a threat of adverseimpact to human health.

Lead Table 3 shows that the average lead concentrations inthe soils of each of the excavated ponds and of all of theponds combined are within the range of backgroundconcentrations. Additionally, the estimates of healthimpacts presented in Attachment I show that theconcentrations of lead in the excavated soils of the pondarea and in the groundwaters underlying the pond area do notpose a threat of adverse impact to human health.

Zinc Table 3 shows that the average zinc concentrations inthe soils of the excavated ponds are above the range ofbackground concentrations. However, the estimates of health

ICFTECHSOLO(J\ INCUR POR \TF.D

impacts presented in Attachment I show that theseconcentrations and the assumed concentrations of zinc in theunderlying groundwaters do not pose a threat of adverseimpact to human health.

Cyanide Table 3 shows that the average total cyanideconcentrations in the soils of the excavated ponds are abovethe range of background concentrations. However, theestimates of health impacts presented in Attachment I showthat these concentrations and the assumed concentrations oftotal cyanide in the underlying groundwaters do not pose athreat of adverse impact to human health.

Based on these conclusions, I request your approval tobackfill and close the ponds in the manner described in the PhaseII Abatement Plan dated October 9, 1989. I do not believe thatadditional removal of any reasonable amounts of pond soils willsubstantially reduce the concentrations of copper, zinc and/orcyanide currently existing in the excavated ponds. Additionally,as shown in Attachment I, I do not believe that any additionalremoval of pond soils is necessary to protect the public health.

As you know, we will be meeting with the Virginia Departmentof Waste Management to develop and eventually execute a consentorder calling for the performance of a remedial investigation andfeasibility study. I envision that this study will primarilyfocus on describing the quality and character of the groundwatersunderlying the pond area. I suspect that this study will showsome degradation of these groundwaters but also will show thatthis degradation is not causing unacceptable impacts on humanhealth or the environment. If this study shows otherwise, it ismy opinion that it will identify a groundwater reclamationprogram rather than the removal of additional soils as the mosteffective remedial measure to correct the situation. Therefore,it is my opinion that it is not necessary to leave the pondsunclosed until the conclusion of the remedial investigation andfeasibility study which could take 6 to 12 months.

I will be happy to discuss this recommendation with you andthe Virginia Department of Waste Management.

Sincerely yours,

Gary N. DietrichSenior Vice President

TABLE 3 (cont.)

Notes:

Except as indicated below, each value is the concentrationmeasured in the surface 6-inches of soil from the respectivepond surface following removal of all sludge and contaminatedsoils from the ponds. Each value derives from a compositesample made up of five samples taken from the respective pondsurface either after the initial removal of sludge and soil inJuly and August 1988 or after the additional removal of soil onthe floor of the new pond, the north, east and south sides ofthe southeast pond and the floor and east, south and west sidesof the northwest pond in November 1988. These values werereported in Table 3 of the letter to Dr. Walter Lee datedJanuary 11, 1989.

The values for chromium, copper, lead and zinc for the bottomsof the southwest, southeast, northwest and northeast ponds arethe averages of the concentrations measured in the surface 6-inches and the underlying 6-inches of soil from the respectivepond surfaces following removal of all sludge and contaminatedsoils from the ponds. Each concentration used in computingthese averages derives from a composite sample made up of fivesamples as described above. These concentrations were reportedin Table 3 of the letter to Dr. Walter Lee dated January 11,1989.

The values for chromium, copper, lead, zinc and total cyanidefor the bottom of the old pond are the averages of theconcentrations measured in the surface 6-inches and theunderlying 6-inches of soil from the east half and the westhalf of the bottom of this pond following removal of all sludgeand contaminated soils. Each concentration used in computingthese averages derives from a composite sample made up of fivesamples. These concentrations were reported in Table 3 of theletter to Dr. Walter Lee dated January 11, 1989.

The values for total cyanide for the bottoms of the southwest,southeast and northeast ponds are the averages of theconcentrations measured in the surface 6-inches and theunderlying 6-inches of soil from the respective pond surfacesfollowing removal of all sludge and contaminated soils from theponds.

Each concentration used in computingthese averages derives from a composite sample made up of fivesamples collected from the respective pond surface. Theseconcentrations are reported in Table 1 of this letter.The values for total cyanide for the bottom of the northwestpond are the averages of the concentrations measured in thesurface 6-inches and the underlying 6-inches of soil fromsamples collected in November 1988 and the concentrationsmeasured in each of the 6-inch intervals of the two-foot coresamples collected in January 1989, both sets of samples beingcollected after the removal of all sludge and contaminatedsoils from the ponds. Each concentration used in computingthese averages derives from a composite sample made up of fivesamples collected from the respective pond surface. Theseconcentrations are reported in Table 1 of this letter.

The average values shown for each constituent for each pond arethe averages of all bottom and side concentrations for theconstituent for the pond as delineated above. Becausebackfilling of the ponds will be accomplished by leveling thepond dikes and moving the soil in these dikes onto the bottomof the ponds, the existing surface soils of the bottoms andsides of the ponds will be intermingled and left in place at adepth of about 4 to 6 feet below the final graded groundsurface of the pond area. Thus, the average values shown inthe this table will reasonably represent the subsurface soilconcentrations of the constituents that will exist under eachpond following backfilling of the ponds.

The overall average values shown for each constituent are theaverages of all bottom and side concentrations for theconstituent for all of the ponds. Because of the backfillingmethod described above, these values will reasonably representthe overall average subsurface soil concentrations of theconstituents that will exist following backfilling of theponds.

ATTACHMENT I

ESTIMATED HEALTH IMPACTSFOR WORST CASE EXPOSURES

This attachment provides estimates of the human healthimpacts of worst case exposures to the concentrations ofchromium, copper, lead, zinc and cyanide contained in the soilsand groundwater of the pond area of the Montross site if noadditional soil is removed and the ponds are closed by beingbackfilled with the materials contained in the pond dikes, asproposed and approved in the Phase II Abatement Plan datedOctober 9, 1987.

The worst case exposure scenario used in these estimatesassumes that the Montross site is developed for residential useand that the parcel of land currently occupied by the ponds isused as a residential property occupied by a family that lives onthis property for a period of 70 years. It is further assumedthat this family will draw its entire domestic water supply froma shallow, on-site well which takes groundwater from thesaturated soils underlying the pond area. Therefore, this worstcase scenario assumes that one or more individuals will beexposed to the soils of the pond area and to the shallowgroundwaters underlying the pond area for 70 years.

It is believed that this is clearly a worst case scenariofor several reasons. First, it assumes the development of theMontross property for residential use which appears highlyunlikely because this property is now in industrial use, islocated adjacent to a property which is in industrial use and isunlikely to change from industrial use, and because the urbangrowth of the Montross area appears to be stagnant. Second, itassumes that the pond area will be used as a residential propertyin spite of the fact that the slope of topography of this area isless suited to residential development as compared with thelarger, flat portions of the property. Lastly, and mostimportantly, it assumes that the most exposed individual livingon the property lives there continuously for 70 years, anunlikely event in today's mobile society.

The worst case scenario used in these estimates assumes (1)continuous and exclusive, long-term use of the shallowgroundwaters underlying the pond area for drinking water, (2)continuous, long-term exposure to the soils of the pond areathrough incidental ingestion of and dermal contact with thesesoils and (3) continuous, long-term inhalation of airborneparticulate composed exclusively of suspended soil from the pondarea. These assumptions assume no drinking water consumption,soil exposure or particulate inhalation exposure from othersources over the 70-year long-term expose period. As such, these

A-l

AR300233

assumptions are very conservative.

This attachment estimates the non-carcinogenic healthimpacts of each of the constituents (chromium, copper, lead, zincand cyanide) by separately estimating the oral and inhalationchronic daily intake (GDI) of each of the constituents andcomparing each intake to the an acceptable intake for long-termexposure derived by multiplying the Acceptable Intake Chronic(AIC) presented in Exhibit A-6 of the Superfund Public HealthEvaluation Manual (EPA 540/1-86/060) by 70 kg, the weight of theaverage adult. It also estimates the carcinogenic health impact(potential upper-bound excess lifetime cancer risk) from exposureto chromium through the inhalation of airborne particulatederived from the soils of the pond area. This estimate uses thecancer potency factor for chromium through the inhalationexposure pathway presented in Exhibit A-4 of the Superfund PublicHealth Evaluation Manual and the average weight (70 kg) of theadult male. All estimates for chromium assume that it ischromium VI and all estimates for cyanide assume that it ishydrogen cyanide. These are conservative assumptions.

Exposure Through Drinking Water Consumption

The estimated potential chronic daily intake of eachconstituent through the consumption of drinking water is derivedthrough the following formula:

GDI = C x DI

where: C = the constituent concentration (mg/1) in thedrinking water.

DI = the daily rate(l/d) of drinking waterconsumption.

It is assumed that the daily consumption of drinking water is 21/d. It is assumed that the concentration of the constituent inthe drinking water is one-half of the concentration of thatconstituent measured in the standing water of the new pond, asreported in the second data column of Table 2 of this letter.This assumption assumes (1) that the standing water in the newpond is representative of the groundwaters immediately underlyingthe ponds and (2) that this groundwater is diluted by a factor of2 by inflows of groundwater from upgradient areas before or as itis being withdrawn by the assumed shallow water supply wellserving as the exclusive drinking water supply.

Table A presents the estimated potential chronic dailyintakes of the constituents derived through the use of the aboveformula and assumptions. This table also presents (1) theacceptable long-term intakes (the AIC's from Exhibit A-6 of the

A-2

AR30023if

Superfund Public Health Evaluation Manual multiplied by 70 kg),and (3) the Hazard Indices calculate^ by dividing the GDI of eachconstituent by the acceptable long-term intake for thatconstituent.

Table A shows that the estimated potential chronic dailyrate of intake of each of the constituents through drinking waterconsumption is less than the acceptable long-term intake rate.Thus, Table A indicates that long-term consumption of drinkingwater drawn from the shallow groundwaters underlying the pondarea will not produce an unacceptable health impact.

Exposure Through Incidental Ingestion of Soil

The estimated potential chronic daily intake of eachconstituent through the incidental ingestion of soil is derivedthrough the following formula:

GDI * C x DI

where: C = the constituent concentration (mg/kg) in thesoil.

DI = the daily rate (kg/d) of incidental ingestionof soil.

It is assumed that the daily rate of incidental ingestion ofsoil is 0.0001 kg/d. This is the daily rate for an average adultbecause the estimates assume 70-year exposures during which theexposed individuals are adults for most of the exposure period.Additionally, this daily rate assumes 100% absorption of theconstituent which is conservative.

It is assumed that the concentration of the constituent inthe ingested soil is the overall average concentration of thatconstituent measured in the soils of the pond area. Theseconcentrations are reported at the end of Table 3 of this letter.This assumption assumes that the individuals living on the closedpond area will be exposed to constituent concentrations in thesurface soils of this area that are equivalent to those measuredin the exposed surface soils of the ponds. This is a veryconservative assumption because the currently exposed surfacesoils of the ponds will be situated 2 to 6 feet below the groundsurface by the planned method of backfilling the ponds. Thus,the constituent concentrations in the surface soils of the closedpond area very likely will be the background concentrations ofthe area (see Table 3 of this letter) and, therefore, will beequal to or less than those assumed in these estimates.

Table B presents the estimated potential chronic dailyintakes of the constituents derived through the use of the above

A-3

AK30Q235

formula and assumptions. This table also presents (1) theconstituent concentrations used in this derivation (the overallaverage values presented at the end of Table 3), (2) theacceptable long-term intakes (the AIC's from Exhibit A-6 of theSuperfund Public Health Evaluation Manual multiplied by 70 kg),and (3) the Hazard Indices calculated by dividing the GDI of eachconstituent by the acceptable long-term intake for thatconstituent.

Table B shows that the estimated potential chronic dailyrate of intake of each of the constituents through incidentalsoil ingestion is substantially less than the acceptable long-term intake rate. Thus, Table B indicates that long-termincidental ingestion of surface soils from the pond area will notproduce an unacceptable health impact.

Exposure Through Dermal Contact with Soil

The estimated potential chronic daily intake of eachconstituent through the dermal contact with soil is derivedthrough the following formula:

GDI = C x DI

where: C = the constituent concentration (mg/kg) in thesoil.

DI = the daily rate (kg/d) of dermal contact withsoil.

It is assumed that the daily rate of dermal contact withsoil is 0.001 kg/d. This is the daily rate for an average adultbecause the estimates assume 70-year exposures during which theexposed individuals are adults for most of the exposure period.Additionally, this daily rate assumes 100% absorption of theconstituent which is particularly conservative for the dermalcontact pathway.

It is assumed that the concentration of the constituent inthe contacted soil is the overall average concentration of thatconstituent measured in the soils of the pond area. These arethe same concentrations used for the incidental soil ingestionestimates described above, and they incorporate the sameconservatism described above.

Table C presents the estimated potential chronic dailyintakes of the constituents derived through the use of the aboveformula and assumptions. This table also presents (1) theconstituent concentrations used in this derivation (the overallaverage values presented at the end of Table 3), (2) theacceptable long-term intakes (the AIC's from Exhibit A-6 of the

A-4

A83QQ236

Superfund Public Health Evaluation Manual multiplied by 70 kg),and (3) the Hazard Indices calculated by dividing the CDI of eachconstituent by the acceptable long-term intake for thatconstituent.

Table C shows that the estimated potential chronic dailyrate of intake of each of the constituents through dermal contactwith soil is substantially less than the acceptable long-termintake rate. Thus, Table C indicates that long-term dermalcontact with the surface soils from the pond area will notproduce an unacceptable health impact.

Exposure Through Inhalation of Suspended-Soil Particulate

The estimated potential chronic daily intake of eachconstituent through the inhalation of suspended soil particulateis derived through the following formula:

CDI = C x C' x DI

where: C = the constituent concentration (mg/kg) in thesuspended soil particulate.

C1 = the concentration (kg/m3) of the PM10 fractionof the suspended soil particulate in the airover the pond area.

DI - the daily rate (m3/d) of inhalation.

It is assumed that the daily rate of inhalation is 20 m3/d.This is the daily rate for an average adult because the estimatesassume 70-year exposures during which the exposed individuals areadults for most of the exposure period.

It is assumed that the concentration of the PM10 fraction ofthe suspended soil particulate in the air over the pond area is50 x 10~* kg/m3 (50 ug/m3). This is the Federal standard for theannual mean concentration of the PM10 fraction in the ambientair. It probably is conservatively high because most of the pondarea is likely to have a vegetation cover which will preventattainment of these levels of suspended soil particulate in theambient air over the pond area.

It is assumed that the concentration of the constituent inthe suspended soil particulate in the air over the pond area isthe overall average concentration of that constituent measured inthe soils of the pond area. These are the same concentrationsused for the incidental soil ingestion estimates described above,and they incorporate the same conservatism described above.

Table D presents the estimated potential chronic daily

A-5

AR300237

intakes of the constituents derived through the use of the aboveformula and assumptions. This table also presents (1) theconstituent concentrations used in this derivation (the overallaverage values presented at the end of Table 3), (2) theacceptable long-term intakes (the AIC's for the inhalation routefrom Exhibit A-'6 of the Superfund Public Health Evaluation Manualmultiplied by 70 kg), and (3) the Hazard Indices calculated bydividing the CDI of each constituent by the acceptable long-termintake for that constituent.

Table D shows that the estimated potential chronic dailyrate of intake of each of the constituents through inhalation issubstantially less than the acceptable long-term intake rate.Thus, Table D indicates that long-term inhalation of suspendedsoil particulate derived from the surface soils of the pond areawill not produce an unacceptable health impact.

Combined Exposure Through All Routes

The Superfund Public Health Evaluation Manual recommendsthat the potential non-carcinogenic health impact of the combinedexposure to all constituents through all exposure routes beassessed by adding the hazard indices of all constituents andexposure routes. This is done by adding all of the hazardindices presented in Tables A through D. This results in acombined hazard index of <1.00. Because this combined index isless than unity, there is no need to be concerned about potentialadverse health impacts from the constituent concentrations in thesoil and groundwater of the pond area.

The Superfund Public Health Evaluation Manual alsorecommends, if the combined hazard index (as above described) wasto exceed unity, that the hazard indices for only thoseconstituent/exposure routes producing the same health effect beadded to assess the potential health impacts. Under thiscriterion, the hazard indices for only chromium and copper wouldbe added because only these constituents affect the same organ(the liver). Adding the hazard indices for these constituentsfor all of the exposure routes (see Tables A through D) resultsin a combined hazard index of 0.74. This more realistic combinedindex is significantly below unity and, therefore, indicates thatthere is no need to be concerned about the potential adversehealth impacts from the concentrations of these constituents inthe soil and groundwater of the pond area.

Carcinogenic Risk from Exposure to Chromium Through Inhalation ofSuspended Soil Particulate

The estimated potential upper-bound excess lifetime cancerrisk from exposure to chromium through the inhalation of

A-6

AR30023B

suspended soil particulate in the ambient air of the pond area isderived through the following formula:

Risk = C x C' x DI x CPF/BW

where: C = the constituent concentration (mg/kg) in thesuspended soil particulate.-

C1 = the concentration (kg/m3) of the PM10 fractionof the suspended soil particulate in the airover the pond area.

DI = the daily rate (m3/d) of inhalation.

CPF = the cancer potency factor for chromiumexposure through inhalation.

BW = the average weight of an adult.

The assumed values of the first three factors are the sameas those used above in estimating the health impact for chromiumintake through inhalation of suspended soil particulate. Theassumed cancer potency factor for chromium resulting frominhalation exposure is 41 (mg/kg/d)-1, as reported in Exhibit A-4of the Superfund Public Health Evaluation Manual. The assumedaverage weight of. an adult is 70 kg.

Using the above formula and assumptions, the estimatedpotential cancer risk from exposure to chromium through theinhalation pathway is calculated to be 6.44 x 10~°. This iswithin the acceptable range (10~4 to 10~7) cited in the SuperfundPublic Health Evaluation Manual.
