TES VII Contractor Oversight of PRP Field Activities at the MetalBank Site, Philadelphia, Pennsylvania, May 15 through June 3, 1992

This document summarizes field oversight activities conducted at the MetalBank Site, Philadelphia, Pennsylvania for the Period May 15, 1992 through June3, 1992. The purpose of this trip was to oversee the groundwater sampling.activities conducted at the Metal Bank Site by the PRP contractor and toaccept split samples for submittal to a CLP laboratory. The PRP contractor isHMM Associates, Inc. (HMM), of Concord, Massachusetts. The sampling wasconducted for HMM by Jim Young, the Field Team Leader (FTL), Bill Chapman,Chris Knightman, Mike Summerlin, and Jeff Sydell. TES contractor oversightpersonnel were Ed Moriarty (SAIC) and Ann Johnson (SAIC).

The.TES VII contractor accepted splits of groundwater samples from apredetermined list of monitoring wells provided by Cesar Lee, the EPA RemedialProject Manager (EPA RPM). Three split samples were accepted by the TES VIIcontractor and submitted for analysis to the following laboratories:

1} McCoy & McCoy Inc. for VOC and SVOC analyses

2) Skinner & Sherman for Total and Dissolved Metal analyses

At the request of the EPA RPM, an aliquot of product (oil phase) was collectedby the PRP contractor from monitoring well MW-06 for PCB congener analysis.The sample, along with an additional aliquot for laboratory QC, will be heldat EPA's Region III Central Regional Laboratory (CRL) in Annapolis, Marylanduntil a laboratory is selected.

In addition to the groundwater sampling, HMM planned to conduct slug tests,geophysical tests, and photo documentation of the abandoned building.. The TESVII contractor was not on site to observe these activities.

HMM collected the groundwater samples based on the 'following routine:

1) Prior to inftiefETncj" sampling activities, HMM decontaminated theirsampling equipment following procedures outlined in the approvedSampling and Analysis Plan '(SAP). While sampling equipment wasbeing decontaminated, HMM collected water levels and calibratedtheir field instruments to monitor the air and water while theypurged and sampled the wells. HMM used an HNu photoionizationdetector (PID) to monitor organics in the air.

The following instruments were used to determine the stability ofgroundwater quality parameters prior to sampling:

• HF Scientific Turbidity Meter - to measure turbidity.• YSI Model 33 - to measure salinity, conductivity, and

temperature.• YSI Model 57 - to measure dissolved oxygen.• Omega 80 pH/Oxidation-Reduction Meter - to measure the pH

and Eh.i

1

H1301865

2) . When HMM was ready to start sampling, they would first monitor thewell for organics with an HNu. The water level and total depth ofthe well were measured to determine the necessary volume requiredto purge the well. Once the sampling equipment was ready, HMMwould purge the well. Per the sampling plan submitted by HMM, awell was purged for a minimum of three well volumes. If the waterquality test parameters were all stabilized, the well could besampled. Otherwise, well purging would continue and the purgewater would be monitored until the water quality parametersstabilized or'until the well was purged a maximum of five wellvolumes.

3) When the water parameters stabilized, HMM collected thegroundwater samples. The groundwater samples were collected inthe following order: VOCs, SVOCs, and total and dissolved metals.Each sample was collected with a Teflon bailer that was dedicatedto a specific well. The only exception was the dissolved metalsaliquot, which was collected with a pressurized Teflon bailersystem. This bailer was decontaminated, following the proceduresoutlined in the approved SAP, each time a well was sampled.

4) After the sample aliquots were collected, HMM preserved the 'aliquots for shipment as specified in the SAP. An exception wasthe VOC aliquot, which was first tested for effervescence by theaddition of hydrochloric acid (HC1). If the sample did noteffervesce, the pH was adjusted to less than 2 and prepared forshipment. In the event the sample did effervesce, the aliquot wasdiscarded, a new one poured, and the sample prepared for shipmentwithout pH adjustment. The effect pH adjustment has on the sampleis that it extends the period of time before the sample must beextracted/analyzed.

5) Finally, when all of the samples were preserved, HMM would lock upthe well, clean up the sampling area, move the samples to theirvan, complete their paper work, and decontaminate field equipment(time permitting). HMM would exit the site and deliver thesamples to their hotel where the samples were-picked up by acourier.

Appendix A provides a'detailed log of field activities and observations. Amap also has been provided showing the sampling locations and the area wheregasoline was poured on the site (designated as SI and S2).

The field sampling procedures used by HMM followed the methods set forth inthe Sampling and Analysis Plan (SAP) with the following exceptions:

5/18/92• The probe for the water level indicator was not decontaminated

(only the wire lead was completely decontaminated after eachsampling event). HMM stated in a telephone conference that theydid not want to use acid on the probe during the decontaminationprocedure because the acid might damage the wire sensor. While

AR3Q1866

ERA concurred that the acid step of the decontamination procedurecould be omitted for 'the probe, the probe should be appropriatelyrinsed after each sampling event.

• The TES VII contractor observed that HMM measured all waterquality parameters at the surface instead of downhole. In

•. comments to the PRPs dated 5/1/92, E,PA recommended that the waterquality parameters (dissolved oxygen, temperature, turbidity, •salinity, pH, Eh, and specific conductance) used to determine the

; stability of the groundwater be measured downhole (i.e., in situ).However, in the field HMM stated that they understood they couldcontinue to monitor groundwater quality parameters at the surface.

5/19/92• The TES VII contractor observed that HMM bailed some wells (MW-08

and MW-11) in a 'manner that appeared too aggressive. HMM did notspecifically describe in'the SAPP the technique they would use tobail the wells, but in a May 6, 1992 tele-conference, HMMdescribed a very passive technique to reduce shock to the watercolumn. The TES VII contractor felt the aggressive bailingtechnique used by HMM would result in sample agitation andpossible alteration of groundwater chemistry.

• The TES VII contractor observed that the length of bailer wire ateach well was measured with the bailer on the bottom of the well.As a result, each time the bailer was Towered into the well, ithit the bottom before being raised. The bailer hitting the sumpportion of the well would result in unnecessary agitation of thewater and fines being introduced into (and suspended in) thegroundwater.

proposed not to do an equipment blank (EB) because the bailerswere dedicated. The TES VII contractor pointed out that this wasa deviation from the SAP which stated that samples would becollected in accordance with the methods outlined in the March1991 Field Sampling Plan. The TES contractor requested that at aminimum, HMM should prepare an EB for the filtration bailer.

HMM wanted to collect the VOC sample from MW-08 without preservingthe sample because an earlier round of samples effervesced. TheTES VII contractor pointed out to HMM that this was a deviationfrom the SAP, and requested that HMM test for effervescence ateach well. HMM tested MW-8 VOC samples; they did not effervesce,so the VOC samples were preserved with HC1.

After HC1 was added to VOC vials, the pH was tested in each samplevial. The TES VII contractor suggested that HMM should use afourth vial to test pH rather than risk contamination,volatilization, or spilling one or all of the vials. Thissuggestion was made when the TES VII contractor observed HMMdipping a stirring rod repeatedly into a 40-ml VOC vial during the

AR30I867

pH adjustment. Next, HMM drained the bailer and collected a newaliquot to top off the VOC vials.

• The bailer that was used to collect and filter the dissolved metalaliquot at MW-11 was wrapped in paper towels first and thenwrapped with aluminum foil after decontamination. The papertowels may be a source of contamination especially if there wasany dye on the paper. '

5/20/92• HMM expressed strong dissatisfaction with the decision to collect

equipment blanks from both the dedicated bailer and the filtrationbailer. It was HMM's opinion that they had provided enough blanksto date for the sampling effort. In addition, HMM felt that 2equipment blanks (1 filter, 1 regular) were too much for everywell and deviated from the sampling plan. ,The TES VII contractor

, pointed out that refusing to collect the blanks was a deviationfrom the SAP. The TES VII contractor explained that one set ofequipment blanks/day for each type of equipment used is required,and the requirement is not based on one set of blanks/well.

• During the initial days of the groundwater sampling effort, HMMtried a number of different techniques to purge the wells. Asrequested by ERA, the TES VII contractor instructed HMM to 'selectone method for purging the wells, and not to deviate from theselected method. ERA felt that if the wells were purged usingvarious techniques, it would result in inconsistencies in thesampling effort that would be difficult to explain later. ERAalso wanted to maintain consistency between the samplingtechniques used by BCM (the previous PRP contractor) and HMM.

• HMM returned to MW-2 to collect a new nitrate aliquot because theoriginal sample was dropped and the container was broken.Collection of the new nitrate sample aliquots occurredapproximately 20 minutes after the original samples werecollected.

• The VOC samples for MW-02 did not come from the same bailervolume. HMM first filled the VOC vials, then added HC1 to one ofthe VOC vials to test for effervescence. The sample effervesced,and the VOC vial was dumped out. HMM dumped the remainder of thefirst bailer,- collected a new sample, and aliquoted the sample tothe empty VOC vial. The result was two VOC vials with groundwaterfrom one bailer volume, and the third VOC vial was filled from adifferent bailer volume. Aliquoting different bailer volumes tothe same VOC sample produces inconsistencies in the samplingtechnique, and could result in a loss of sampling precision.Specifically, studies have suggested that considerable imprecisionis introduced into samples collected with bailers, possibly as aresult of differences in operator technique (USEPA, 1991; Tai etal., 1991; Pohlmann et al., undated). In a study comparingconcentrations of volatile organic compounds detected using

AR30I868

various sampling devices, Imbrigiotta et al. (1988) noted that thedata for the samples collected with the bailers exhibited thelowest precision of the seven sampling devices investigated.

• The TES VII contractor suggested (on two occasions) that HMM use afourth VOC vial to test for effervescence. HMM left the VOC vialsopen duringjhe sampling effort (approximately 5 minutes),allowing for possible loss of volatiles.

• Samples from MW-14 for dissolved metals were transferred from thededicated bailer to the filtration bailer, which was inconsistent

; .with the established s-ampling routine. This sample handlingtechnique could result in sample aeration (oxidation).

• . HMM used only deionized (DI) water for their trip blanks, fieldblanks, and equipment blanks. Guidance in the Samplers Guide tothe Contract. Laboratory Program indicates that HPLC-grade watershould be used on the organic samples, and DI water on theinorganic blanks.

5/27/92• The TES VII contractor informed HMM that they would require splits

of HMM's equipment blanks each day of sampling. (The TEScontractor field team provided their own blank water). HMM statedthat providing the additional blanks for the TES VII contractorwould require extra unbudgeted time. Jim Young (HMM) discussedthe issue with Pete Swinick (HMM) and informed the TES VIIcontractor that HMM would provide the necessary splits.

• HMM requested that EPA inform them of the sample locations to besplit. The TES VII contractor explained to HMM that, at therequest of EPA, those locations would only be announced just prior,to the sampling event. HMM explained that they wanted to know theidentity of the wells where splits would be required so that theycould sample all the wells in a single day.

• HMM's field instrument used to monitor pH and Eh failed. As aresult, these water quality parameters were not that measured formonitoring wells MW-4, MW-5, and MW-15. HMM stated they wouldreplace the instrument as soon as possible.

May 15, 1992

11:47 The TES VII contractor field team member (Ed Moriarty) arrived at theMetal Bank Site. The gate was locked, amd HMM was not on site. A notewas found from the previous day (5/14/92), indicating they had samplingequipment problems.

11:53 Exit site to call Jim Young (HMM) at the Sheraton Hotel.

12:05 Passed HMM on, the road and returned to the site. Jim Young stated thatthey were waiting on a second van that has their sampling equipment.

12:10 Moriarty calibrated the field instruments.H?S meter reads 20 ppm on a 26 ppm standard.HNu reads 100 ppm Isobutylene, 5.3 span and background at 0.3 ppm.CGI 261 reads LEL 50%, and 02 20.8%.

12:41 Remainder of HMM crew arrived on site. To maintain security, HMM locksthe gate each time a person enters or exits.

13:14 The TES VII contractor discussed with HMM what the afternoon events wouldentail, and the names of the additional field crew personnel. AdditionalHMM personnel on site were:

Jeff SydellChris KnightmanMike Summer!in.

HMM debated if they would be able to sample a well today. Timeconstraints are an issue with their 6:30 pm flight. Jim Young (HMM) wasattempting to find a later flight. A question was raised regarding theexclusion zone and decontamination.

The T.ES VII contractor described where BCM's hot line (exclusion zone) waslocated and how they decontaminated at each location. In addition, theTES VII contractor mentioned that BCM would store drum, waste at eachsampling location, and collect the drums when the -sampling effort wascomplete.

13:52 HMM will not sample a well today. Rather, they will decontaminate theirequipment and install a staffing gauge (in the stilling well) at alocation near the river to monitor water level from the shore.

14:18 Each well will have dedicated equipment with the exception of a teflonbailer that is>part of the N2 filtration system. This bailer will bedecontaminated between each monitoring well.

HMM's Decontamination steps observed by the TES VII contractor forsampling equipment were as follows:

soap and water ,water rinse

acid rinsemethanolhexanewater rinseair dry wrap in foil, then plastic bags.

14:43 HMM mentioned that John Minihan of Mattioni, Mattioni, and Mattioni was onsite last week (5/6/92) with a video camera while they unloaded drums.

15:12 John Minihan and George Gross arrived on site. Minihan taped some of thedecontamination procedure.

15:31 Decontamination was performed on the:

tygon tubingN2 bailerbailer wire (stainless steel cable with teflon coating).

16:05 The TES VII contractor exited the site for Falls Church, VA. Attempted toreach Ann Johnson (SAIC WAM) unsuccessfully. The TES VII contractor thencalled Holiday Inn to ensure that they hold the 32 oz. amber bottles.

08:30 Departed Falls Church, VA for the Metal Bank Site.

11:30 The TES VII contractor's field team personnel Ann Johnson, and EdMoriarty, arrived on site. Jim Young (HMM), and staff were already onsite preparing to sample.

11:45 John Minihan arrived on site to observe the sampling activity.

11:51 The TES VII contractor prepared sample containers for sample splits. HMMset up the decontamination area and exclusion zone.

12:55 A decontamination station was established outside the gate for boots, anda second station was set-up inside the gate for sampling equipment. Thedecontamination procedure for boots is as follows.:

Alconox, Methanol, and Tap water.

Decontamination of the sampling equipment was the same as the previousweek.

13:10 HMM began decontamination of the dedicated teflon bailers which were to beused in sampling the monitoring wells.

13:20 HMM decontaminated the water level indicator following the same proceduresused for the bailers.

The probe for the water level indicator was not decontaminated.

13:30 HMM decontaminated the interface probe following the same procedure usedfor decontaminating bailers.

The probe was decontaminated.

13:35 Moved equipment to monitoring well MW-11.

13:45 HNu at 0 ppm background, and 0 ppm in the well head.

13:50 HMM measured the water level using a water level indicator at MW-11:

Water level at 12.02' top of well casing (TOC).Water level at 12.46' top of PVC (TOP) stick.Bottom of well 19.46' from TOP.Bottom of well 19.91' from TOC.

No product on probe or in well.

Weather is overcast, approximately 75°F, slight breeze.' There has been anintermittent sweet odor from the outfall.

A-35R30!875

13:55 HMM will be required to purge 14.5 gallons (gal) from MW-11 for 3 wellvolumes.

14:11 HMM began to purge MW-11. Water quality (WQ) parameters will be monitoredbeginning with the first volume to be pumped out. The pump can only drawapproximately .5 gal/min. HMM proposes to monitor water level whilepumping. The purpose of monitoring the water level is to ensure that theydo not pump the well dry.

14:25 The hose for the pump'is drawing from the bottom portion of the well.

purge rate is approximately 100 ml/minwater is light brown and clear

14:45 Ann Johnson exited site to call Cesar Lee (ERA WAM) about the difficultythat HMM was having purging the well. Cesar was not available.

15:05 HMM measured the water level at 12.03' TOC in well MW-11. Water level inthe well has not changed significantly.

15:30 Ann Johnson exited site to speak to ERA about the purge rate problems.

MW-11 water quality tests for stabilization: .

16:00 Ann Johnson contacted Cesar Lee who said it was OK for HMM to use bailersto purge the wells, if they used dedicated bailers. Rather than HMMcontinuing to use the pump, Cesar said bailers could be used to purge allof the monitoring wells.

16:15 HMM began to decontaminate the remaining bailers.

Bailers are 3' X 1 3/4" diameter.1050 mL capacity.

The hose used to transfer purge water to the bucket fell out of thebucket, and approximately 200-300 mis. was caught on the plastictarp.

16:38 HMM ceased pumping water from MW-11. Five gallons were removed from thewell and transferred to the waste drums.

ftR3Qi876

16:45 HMM started to purge MW-11 with the bailer.

16:50 Water from bottom of well is black.

The bailer was lowered to the bottom of the well then pulled back; up. As a result of the bailer hitting the bottom of the well,

sediment in the well was stirred up into the water.

16:55 The water level in MW-11 was measured at 12' TOC with two bailers emptied.Third bailer full draws up black water.

16:57 HMM measured the concentration of VOCs in the water after the fourthbailer full at 0 ppm.

17:00 The water level was measured again at 12' TOC. The bailer was allowed totouch bottom of well each time before it was brought up. Water color wasvery different (darker) than water color observed while the pump was usedto purge the well. The purge water drawn up with the pump was lightbrown, and the purge water from the bailers was black. In addition, thepump intake hose was moved up and down in the well. The bailer fell tothe bottom and was pulled back up.

17:10 HMM continues to measure the water in MW-11 (,11.99' TOC) to ensure thatthe well will not dry up.

17:13 The HNu instrument was non detect (0 ppm) for organics at MW-11.

17:18 HMM completed the WQ analyses tests and the rest of purge water wasdischarged into bucket.

17:20 Field water quality parameters measured on second well volume. The bottlewas left open while temperature, salinity, and specific conductance (SP)were recorded.

Dissolved Oxygen probe could be measured downhole but HMMrefuses.

Turbidity - sample poured into vial (particulate could havesettled).

The stability tests were conducted on the 8th gal. bailed from the well.

17:55 HMM reached 12 gal. mark on MW-11.

18:20 HMM completed 3 well volumes (-15 gal) and proceeded with water qualityparameters (see Table 1).

19:05 HMM called an end to the day. They will not sample MW-11 until 'tomorrow.On Tuesday, HMM will purge/sample MW-11 and another well, then move to athird'sampling location.

19:30 The TES VII contractors (Moriarty and Johnson) departed site.

08:15 The TES VII contractor (Moriarty) arrived on site. Jim Young and JeffSydell of HMM were on site preparing to sample MW-11.

08:45 Jim O'Brien (HMM) arrived on site to perform an on-site audit of HMM.

10:00 HNu readings at MW-8 were:

Background - 0 ppm.Well head - 0 ppm.

Weather is approximately 70°F with a breeze from the north and the sky isclear.

10:20 HMM started to purge MW-8:

MW-8 will require approximately 3 gals, for 1 volumeWater level 11.24' from TOP.Water level 11.71' from TOC.Water is brown and cloudy, and appears to have an organicsilt.

The bailing was more aggressive at MW-11 than at MW-8; this may stir morefines up in the well. Bailer wire length for both wells is measured withthe bailer on the bottom of the well. This means that each time thebailer is lowered into the well, it may hit the bottom before beingraised.

11:45 Cesar Lee (ERA) arrived on site to observe the sampling activity.

12:15 The TES VII contractor departed the site to call Ann Johnson (SAIC, FallsChurch, VA). ERA and Jim Young (HMM) remained on site. The sampling wasdelayed because the van with the sample bottles was sent to get DI inReading, PA and had not returned.

13:13 The TES VII contractor returned to site to find HMM, ERA, and John Minihanon site. Still no activity.

13:18 The second HMM van (with the DI and sample bottles) arrived.

13:30 ERA exited the site for lunch.

14:05 All parties (HMM, ERA, the TES VII contractor) are back on site.

14:50 HMM started to collect samples at MW-11:

The VOC sample effervesced when HCL was added to the groundwater, therefore, VOC samples will be collected withoutpreservation.HMM proposed not to do an equipment blank (EB) because thebailers are dedicated. The TES VII contractor stated theywould still like an EB for the filtration bailer, and HMMagreed.HMM will dispense the sample aliquot from the bailer to alljars within each parameter until the jars are filled.HMM discharged a small portion from the bailer to the wastebucket to clean the tube, and/or to clear sediment.HMM commented that by spreading the sample around, there is aconcern for aeration of the samples- as the jars are filled.The TES VII contractor suggested they cap the jars betweenevents, but there was no response from HMM.This well has HMM's Lab QC - MS/MSD.Silt from the well was blocking up the nitrogen (N2)filtration bailer causing problems with filtration.

Filtration process:

1) Sample is collected in the filtration bailer.2) N2 pressure hose and filter are attached.3) Pressure is turned on at the nitrogen tank.4) Sample flow is controlled through a stop-cock.

One problem encountered by HMM was the filtration bailer cloggingup. If there is too much sediment in the sample, the bailer blocksup and the sample cannot flow.

17:35 Cesar Lee (ERA), Jim O'Brien, and Chris Knightman (HMM), departed the sitefor the day. O'Brien and Knightman will not return until next week. Dueto the delay in sampling MW-8, HMM elected to purge the well again.

18:40 HMM started to sample MW-8. The equipment blank also was collected forthe dissolved metals.

18:52 HMM wanted to collect the VOC sample without preservation (pH adjustment).

The TES VII contractor instructed HMM to test each well, andnot to assume that if one well effervesced, they all would.HMM tested MW-8 VOC samples and they didn't bubble. Next HMMopened the other vials to preserve the samples, then drainedthe bailer and collected a new aliquot to top off the VOCvials.

19:20 HMM started to collect the dissolved metals aliquot.

The bailer used to collect/filter was wrapped in paper towels,and then foil after decontamination (MW-11).

20:30 The TES VII contractor exited site for hotel. At the hotel, a phonereport will be left for Cesar Lee (EPA) and Ann Johnson (TES VIIcontractor WAM).

21:00 Messages were left for EPA and the TES VII contractor WAM in Falls Church.

08:50 Moriarty (the TES VII contractor) arrived on site. HMM was not at thesite. Per a conversation held on 5/19/92, HMM stated that they wouldarrive on site between 8 and 9 am.

09:40 Jeff Sydell (HMM) arrived on site. HMM explained to the TES VIIcontractor that because HMM.was out in the field until 21:30, they decidedto make the day an easy one. The activities for the day would be asfollows: ;

measure water levels.decontaminate additional equipment.

• - no sampling.

09:50 George Gross (Property Manager) entered the site to cut the grass in thefield.

10:15 HMM exited the site.

11:02 The TES VII contractor left the site to call the TES VII contractor inFalls Church. Ms. Johnson answered the questions that were brought up inthe field on 5/19/92.

; - Equipment blanks are required from the dedicated bailer inaddition to the filtration bailer.The TES VII contractor explained to Ann Johnson that HMM wasnot on site, why HMM was not on site, and their abbreviatedschedule for today..

11:39 The TES VII contractor returned to Metal Bank Site. The gate was lockedand Mr. Gross was off of the property. HMM has not returned to the site.

12:54 HMM entered the site, and spoke to the TES VII'contractor.

HMM will decontaminate equipment, and check water levels, timepermitting.

;. - HMM stated that they would try to sample three wells tomorrow.In addition, HMM would like to know from which wells the TESVII contractor intends to collect their splits so that theymay accommodate us sooner.HMM expressed strong dissatisfaction regarding the decision tocollect equipment blanks for both the dedicated bailer, andthe filtration bailer. HMM felts that two (2) equipmentblanks (1 filter, 1 regular) were too much for every well anddeviated from the sampling plan. The TES- VII contractorexplained that the requirement is for one set of equipmentblanks each day, and not per monitoring well.

13:15 The TES VII contractor exited site to call for guidance on the aboveissues.

Ann Johnson (TES VII contractor WAM) 'stated that hmm was

required to provide one equipment blank/day/type (i.e., 1filter, 1 everything else), based on BCMs approved samplingplan.ERA requested that the TES VII contractor not identify fromwhich wells they intend to collect the sample splits.

13:50 The TES VII contractor returned to the site. HMM was decontaminatingbailers.

HMM informed the TES VII contractor that they will be using ahigh capacity peristaltic pump to purge wells tomorrow.HMM felt the equipment blank was a deviation on the work plan,and that the equipment blank would result in additional timeand cost (bottles, lab cost).

14:10 The TES VII contractor exited the site to inform Ann Johnson (TES VIIcontractor WAM) of HMM's intention to use the high capacity pump.

Johnson will notify Cesar Lee (EPA WAM) and provide hisresponse back to the field by voice mail.

14:20 The TES VII contractor returned to the site. HMM continued todecontaminate sampling/field equipment.

16:05 The TES VII contractor took HMM out to the river to familiarize them withthe area. HMM may attempt to install the staff gauge on the still well onFriday.

16:15 Both parties returned to the decontamination station at the gate. HMMtook the rest of the day to organize sample bottles for the next day'ssampling events.

16:43 The TES VII contractor exited the site for the day. HMM intends to startthe next day between 8 and 9. HMM expects to get 2 wells sampled (not 3),because they have some decontamination left to finish.

17:15 The TES VII contractor made calls to EPA and the TES VII contractor WAMFalls Church to provide an update on the day's events.

17:47 HMM collected samples from MW-3.

The VOC sample effervesced, therefore, the VOC aliquots will. not be preserved with HCL.The VOC samples didn't come from the same bailer.

HMM filled the VOC vials, added HCL, and tested, thesample for effervescence.One of the sample VOC vials was used to test foreffervescence.

1 • The sample failed, and the sample was dumped out..Jim Young (HMM) dumped the remainder of the first bailerout, collected a new aliquot for the third vial, andpoured a new aliquot into the VOC vial.

The TES VII contractor suggested on two occasions for HMM to use a fourthvial to test for pH and effervescence. The suggestions were not followed.In addition, it was observed the HMM personnel do not close the VOC vialsas soon as possible. This could result in additional volatilization oforganics from the sample.

10:00 The TES VII contractor observed HMM take their van on to the site.

HMM intends to decontaminate the van at the end of each day.There will be a box frame made with planks (to create a tub)upon which the van will drive. The tub will be big enough toclean one axle at a time.HMM became exasperated when notified that the TES VIIcontractor will also require equipment blanks:

1) This requires more time on HMM's part.2) HMM requested that ERA inform them of any other wells

that need to be split so that HMM could do them in oneday.

In addition, HMM threatened they may be forced to refuse toprovide split samples if the TES VII contractor did notcooperate, and .tell them which wells ERA required splits.

10:55 HMM started to collect today's equipment blanks. The TES VII contractorwill split these equipment blanks (MB-EB-01).

08:00 Moriarty (the TES VII contractor) arrived on site. HMM had not arrived onsite so the TES VII contractor started filling out paperwork for the dayssampling event. The weather was cloudy/overcast, windy, and thetemperature was approximately SOT.

09:00 HMM arrived on site. Chris Knightman and Jeff Sydell (HMM) moved on siteto start the slug tests for today.

09:40 The remainder of HMM personnel arrived on site.

HMM informed the TES VII contractor that they would attempt tocollect samples from the remaining wellsThe TES VII contractor informed HMM that they would require thefollowing from MW-6:

1) an equipment blank for the product sample.2) product and QC samples (if any remained) after HMM collected

their split. .3) standard round of samples and equipment blanks.

10:00 The TES VII contractor prepared the trip blank (MB-TB-03) and placed thesample on ice.

10:15 The field blank was prepared and placed on ice (MB-FB-03).

10:35 The TES VII contractor continued with paperwork while HMM prepared tosample.

11:00 HMM prepared to collect product at MW-7.

HNu measurements at MW-7 in the casing and well head were 0ppm.Water level was 12.30' TOP, and 12.58' TOC.Bottom of well was 18.56' TOP, and 18.82' TOC.The interface probe didn't detect any product.HMM elected to pull the stilling tube and attempted to collectany product that may exist.

12:17 HMM started to purge PW-10. The samples were to be collected through thestilling tube installed the previous day (6/1/92). HMM continued with theslug tests at monitoring wells that were already sampled.

iOne well volume 3.16 gal.The TES VII contractor was unable to collect the water levelinformation.

Water Quality parameter results are as follows:

12:57 HMM "officially" jiotified the TES VII contractor that the PRP steeringcommittee approved HMM's plan to perform slug test while they completedsampling.

.HMM would only run slug tests on wells previously sampled.

13:20 HMM started to purge MW-7 through the stilling tube. One well volumeequals 4.069 gal.

Purge water was black and opaque.

13:36 The TES VII contractor exited site to call the TES VII contractor FallsChurch.

Bob Stewart will check on extending the sample case number forthe samples.Ed Moriarty can stay one more day if required.

14:05 The TES VII contractor returned to the Metal Bank site.

14:44 HMM continued to purge MW-7; the water was black with heavy sediment, verylight sheen, and opaque.

Note aggressive purging with bailer at MW-7.

Water Quality parameter results are as follows:

08:11 The TES VII contractor arrived at the Metal -Bank site.

HMM had not arrived on site.The TES VII contractor will start on paperwork and prepare thetrip and field blanks.

08:24 HMM arrived on site and started to setup for the sampling activity.

10:00 The TES VII contractor prepared the trip blank and placed the sample onice (MB-TB-03).

HMM started to decontaminate the filtration bailer.

10:15 The TES VII contractor made the field blank (MB-FB-08) and placed thesample on ice.

10:22 HMM started to collect their equipment blanks.

Throughout the groundwater sampling activities, HMM has usedone of the 3 VOC vials to test pH (not an additional vial thatmay be discarded).

10:45 The TES VII contractor received their split of the equipment blank (MB-EB-03), and placed the sample on ice.

10:30 HMM started to purge MW-6:

HNu reading at 1.5 ppm in well head.Water level from stilling tube 14.89'. The stilling tube wasraised out of the well -6-9" before measurement.One well volume is 3.3 gal.The water is black and very turbid, the water is giving off apetroleum/organic odor.Product appears to be in the groundwater and clinging tosuspended solids.The Specific Conductance, Salinity and pH instruments are notfunctioning, so ground water stability will be determined bythe Temperature, Dissolved oxygen and Turbidity. HMM willpurge 5 well volumes to ensure that the well is stabilized.

16:15 HMM started to collect product from MW-6. If there was enough product inthe well, the TES VII contractor also would accept a split. HMM didn'tstate that they were going to analyze for PCB congeners,

• . - Small amount of product in bailer.Water is clear with some suspended solids.

. - Uncertain if there is enough for analysis.

17:50 Exited site after packing samples and completing paperwork.

18:19 Delivered the samples to Federal Express:

Sample shipment information:

13:17 The TES VII contractor accepted sample splits from HMM for MW-6. Thesamples were then placed on ice.

14:05 The TES VII contractor moved to the parking lot to pack samples and dopaperwork.

14:56 The TES VII contractor left the site for ice, and to call the TES VIIcontractor WAM.

i

15:25 The TES VII contractor returned to Metal Bank to pack samples, completepaperwork, and discuss with HMM the schedule for the rest of the week.

16:21 The results of the discussion with HMM were as follows:

If HMM can gain access to the buildings, they will take picturestomorrow, and collect water levels. Otherwise, HMM will return toBoston.

Jim Young (HMM) called John Minihan about possible access to thebuilding. Minihan will inform HMM later today, who in turn willcall Cesar Lee (EPA).

13:11 The TES VII contractor (Ed Moriarty) arrived on site at Metal Bank.

HMM was on site setting up for today's sampling event.Cesar Lee (EPA) was also on site.

HMM spoke to the TES VII contractor about Friday's events.

2 persons entered the site and poured approximately 5 gallonsof gasoline onto the pavement. The persons were detained byJohn Minihan until the police arrived. The individualsclaimed to be dumping old/bad gas from their power boat. Eachperson was holding a.5 gallon gas can that is seen on outboardboats. The spill location is identified on the site diagramas SI and S2.

13:55 John Minihan arrived on site.

14:03 The TES VII contractor and EPA exit site for lunch.

15:10 The TES VII contractor and EPA returned to the site.

HMM is out on site.

15:49 HMM prepared to first collect product, then purge and sample PW-10.

PW-10 was determined last week to have product in the well.The well will first be sampled for' product before the groundwater is collected.HNu measurement in casing and well head was 0 ppm.Product at 14.78' TOP, and 15.10' TOC.Water is at 14.81' TOP, and 15.13' TOC.Bottom of well is 20.77' TOP, and 21.09' TOC.

16:26 The oil phase (PW-10) was too thin to separate the product from the water,so HMM elected to send both phases to the lab.

HMM only dips the bailer far enough into the well to getproduct without too much water.

17:20 Cesar-Lee (EPA) exited the site.

17:55 HMM will install a stilling tube into PW-10, then pack up for the evening.MW-6 and MW-7 have stilling tubes installed from the BCM effort. HMMplans to sample, slug test, and photo document the buildings during thisweek. Next week the geophysics are scheduled.
