2.3 Site Inspection

On March 10, 1988, Robert Bird, Senior Hydrogeologist of Briggs Associates, Inc. (BAI), conducted a visual inspection of the building interior and surrounding grounds at the subject site and interviewed an employee of Precise Engineering, Alan Holmes, regarding site history and operational practices.

A one-story brick and concrete block building, occupying approximately 30,000 square feet near the southeast corner of the property, is located on the subject site. The building houses the manufacturing and administrative operations of Precise Engineering Inc. Refer to Figure 3 - Building Plan.

The majority of the building interior is occupied by metal stamping and machining equipment and appurtenances. Administrative offices for the company are located in the northeast corner of the buildingr A paint room, housing dip-painting operations, is located near the southwest corner of the building. A floor drain with an exterior surface discharge is located within the paint room. Two (2) solvent degreasing tanks are located within the building. One (1) of the tanks is located along the southern wall, near the paint room. The other tank is located midway along the western building wall. Perchloroethylene (Tetrachloroethylene) has been used as the cleaning solvent in both tanks since 1978. A recent trial use of 1,1,1-Trichloroethane as the degreasing solvent has been abandoned.

The grounds surrounding the building were inspected for visual evidence of a release or threat of a release of oil or hazardous material. Refer to Figure 2 - Site Plan.

The grounds along the eastern side of the building revealed an area of metal stock and scrap storage near the southeast corner of the building. The leaching field for the waste water disposal system is also located near the southeast corner of the building.

The narrow parcel of land between the southern building face and the abutting residential properties is utilized for the storage of miscellaneous metal scrap. The surface discharge pipe from the paint room.floor drain was inspected. The soils in the vicinity of the pipe did not exhibit visual evidence of stains commonly associated with the release of hazardous materials.

The portion of the grounds located to the west of the building is utilized for the storage of metal stock and scrap, metal machining equipment for spare parts, and parking. Numerous areas of oil stained soil were observed beneath and surrounding various pieces of machinery. Two (2) small truck bodies are used for the storage of gas cylinders and liquid containers, respectively. The truck body used for liquid container storage is located approximately 80 feet west of the southwest corner of the building and contains 55-gallon drums of virgin and waste oils and perchloroethylene and 5-gallon buckets of oils and greases. The truck body used for gas cylinder storage is located approximately 40 feet west of the building by 100 feet north of the southern property boundary and contains gas cylinders containing propane, acetylene, oxygen and argon as well as assorted

gasoline cans. A 38-foot trailer is located approximately 100 feet west of the northwest building corner and contains numerous 55-gallon drums of unknown contents. Several piles of soil reportedly removed from the railroad beds which abut the subject site to the north are present to the west of the building.

The area located to the north of the building is utilized for the storage of large machinery. Numerous areas of oil stained soil were observed beneath and surrounding the machinery.

Abutting properties to the subject site are identified as Eastern States Steel to the west, West Union Street to the north and residential properties to the east and south.

The western abutter, Eastern States Steel, presently utilizes their property for the storage of bulk steel. The property was the site of a foundry from the early 1900's to the 1960's. The site also has been utilized as an automobile salvage yard in the past.

A vacant lot is located across from the subject site, on the north side of West Union Street. Numerous 55-gallon drums were observed on this property.

4.0 FIELD INVESTIGATIONS

4.1 Test Borings

A total of three (3) soil test borings, designated B-1 through B-3, were drilled by BAI on February 15, 1988. Test borings were installed to a maximum depth of 15.0 feet below existing ground surface to explore subsurface conditions. BAI personnel supervised the installation of three (3) groundwater observation wells, designated OW-1 through OW-3, in boreholes B-1 through B-3, respectively. Observation well locations are shown on the Site Plan included as Figure 2. Test boring logs are included in Appendix A.

Testborings were installed using a 3 Va" I.D. hollow-stem auger. Soil samples were collected at five (5) foot depth intervals in accordance with ASTM D1586 "Penetration Test and Split Barrel Sampling of Soils". Soil samples obtained from the test borings were classified by visual and textura! examination in accordance with the Unified Soils Classification System.

During the installation of borings B-2, olfactory evidence of solvents was encountered in the sample collected from the depth interval of 1.0 to 3.0 feet below ground surface.

4.2 Observation Wells

Groundwater observation wells, designated OW-1 thru OW-3, were installed in boreholes B-1 thru B-3, respectively, to obtain groundwater samples for laboratory analyses. Observation well installations were supervised by BAI personnel See Figure 2 for observation well locations.

The wells were constructed of 1.5-inch I.D. Schedule 40 Polyvinyl Chloride (PVC) casing with threaded joints. Well screen sections consisted of 10-foot lengths of 0.01.0-inch slotted casing. Silica sand was employed as a filter pack around the well screen to a height of approximately two (2) feet above the top of the well screen. A minimum 0.5-foot thick bentonite pellet seal was installed in each borehole above the top of the sand. Clean native material or sand was added to within one (1) foot of the surface, where necessary. A gate box was cemented in place at the surface of each well installation to provide wellhead protection from vandalism and surface water infiltration. Groundwater observation well reports with specific construction details for each well are included as Appendix B.

5.0 SAMPLING AND ANALYSIS

5.1 Subsurface Soils

A total of 11 subsurface soil samples collected during the installation of test borings B-1 through B-3 were analyzed for total ionizable compounds in the sample jar headspace using a Photovac TIP II photoionization meter. A summary of the analytical method and the analysis report are included in Appendix C.

Concentrations of total ionizable compounds in soil samples collected from the three (3) borings ranged between 0.0 ppm and 142.7 ppm. The highest Concentrations were detected in the soil sample collected from the depth interval of 1.0 to 3.0 feet below ground surface in boreholes B-2 and B-3 and the depth interval 5.0 to 7.0 feet in borehole B-3.

A total of six (6) soil samples (BAI Lab Nos. 7068A-F) were analyzed for total petroleum hydrocarbon content by Method 503B.E (Standard Methods for the Examination of Wastewater, 16th Ed, 1985). In addition, three (3) samples (BAI Lab Nos. 7068A, C, and E) were also analyzed for volatile organic compound concentrations via U.S. EPA Method 8024. Laboratory results for soil analyses are summarized in Table 2 and a complete analytical laboratory report is included in Appendix D.

5.2 Groundwater

On February 22, 1988, groundwater samples were collected by BAI personnel from each of the three (3) observation wells installed on-site. Sampling was conducted in accordance with Environmental Protection Agency recommended protocols for equipment decontamination, sample collection, sample storage and chain-of-eustody.

A teflon bailer was pre-cleaned prior to well purging using a four (4) step process: the bailer and teflon-coated cord were washed in a soap solution, rinsed in tap water, rinsed in a 20% solution of methanol in distilled water, and finally rinsed in distilled water.

The clean bailer was carefully lowered to the water table and submerged one-half its total length. Upon removal, no free-phase product was observed on the water surface in the bailer in any of the three (3) observation wells.

Prior to groundwater sample collection, the well was purged of a minimum three (3) times the well-casing water volume using a pre-cleaned teflon bailer. Samples for laboratory testing were obtained using a teflon bailer. Samples for total petroleum hydrocarbon analysis were stored in a pre-cleaned 1 liter glass bottle. Samples for volatile organic compound (VOC) analysis were stored in a pre-cleaned 40 ml glass vial with a teflon septum. Samples for VOC analysis were carefully decanted from the bailer to minimize aeration. All water samples were packed on ice in an insulated cooler for transport to the BAI analytical laboratory. A chain-of-custody sheet was completed to account for sample handling.

Each groundwater sample was analyzed for volatile organic compound (VOC) concentration by EPA Method 624 and total petroleum hydrocarbon concentration by Method 503B,E (Standard Methods for the Examination of Wastewater, 16th Ed, 1985). The samples collected from observation wells OW-1, OW-2 and OW-3 were assigned BAI Laboratory Nos. 7096B, 7096C and 7096D, respectively. In addition, a composite sample collected from OW-1, OW-2 and OW-3 was assigned BAI Laboratory No. 7096A and analyzed for RCRA Metals concentrations. Laboratory results for groundwater analyses are summarized, in Table 3 and a complete analytical laboratory report is included in Appendix D.

6.0 CONCLUSIONS AND RECOMMENDATIONS

6.1 Summary of Findings

Briggs Associates, inc. has completed the scope of services defined in our Proposal Number MA88.123.0 dated January 25, 1988. A summary of the findings of our investigation is presented below:

Site Research

• A review of records on file with the Department of Environmental Quality Engineering - Southeast Region and the Town of East Bridgewater Fire and Health Departments reveal that the property identified as 24 West Union Street in East Bridgewater, Massachusetts and abutting properties have not been the site of a reported release of oil or hazardous materials to the environment as of the date of this investigation.

• Historical use of the 24 West Union Street property has included the manufacturing of wooden and plastic shoe lasts and boat building in addition to the present metal machining business.

Soil Conditions

• On September 1, 1987, Haley and Aldrich, Inc. personnel discovered evidence of oil and solvent contamination in two (2) test pits excavated on the Precise Engineering property.

• Soil samples collected from test borings drilled by Briggs Associates Inc. on February 15, 1988 revealed olfactory evidence of solvent contamination in test boring B-2, located adjacent to the truck body historically used to store solvents. The contamination appeared to be greatest in the sample collected from the depth interval of 0 to 2 feet below ground surface.

• Photoionization Meter analysis of 11 surface and subsurface soil samples collected from three (3) soil borings revealed elevated concentrations of total ionizable compounds in three (3) samples collected from soil borings B-2 and B-3.

• Levels of total petroleum hydrocarbons in the soil samples from borings B-1, B-2, and B-3 ranged between 60 and 11,000 mg/Kg (ppm). The highest concentrations were detected in samples collected from the depth interval of 0 to 2 feet below ground surface in each of the test borings.

• The priority pollutant volatile organic compounds (VOCs) Tetrachloroethylene and Xylene were detected in the soil sample collected from the depth interval of 0 to 2 feet in B-2. The VOC Xylene was detected in the soil sample collected from the depth interval of 0 to 2 feet in B-3.


Page 14

Groundwater Conditions

• No free-phase petroleum products were observed in the observation wells during groundwater sample collection on February 22, 1988.

• The concentration of total petroleum hydrocarbons in groundwater samples collected on February 22,1988 were: OW-1 = 1.8 mg/L; OW-2 = 3.6 mq/L* and OW-3 = 3.2 mg/L. '

• A total of 12 Priority Pollutant volatile organic compounds were detected in groundwater samples collected from OW-1, OW-2 and OW-3 on February 22,

car 1988. The concentrations of Benzene, Tetrachloroethylene, Toluene,' . Jrichloroethylene and Vinyl Chloride in the groundwater beneath the site exceed state and/or federal advisories, guidelines and criteria for drinking water.

• The concentrations of RCRA metals in composite sample No. 7096A, collected from OW-1, OW-2 and OW-3, were within the limits criteria for Class I groundwater (314 CMR 6.06).

• Based on water table surface elevations measured on March 3, 1988, site specific groundwater flow is southeast.

• Based on information provided by the Town of East Bridgewater Water Department, residential properties located downgradient (south) of the subject site are provided with town water.

6.2 Conclusions

Based on the investigative methods described herein and interpretation of the data collected, Briggs Associates, Inc. concludes the following:

• The subject property, located at 24 West Union Street, East Bridgewater, •- Massachusetts, has been the location of a release of hazardous materials to

the environment, as evidenced by the presence of priority pollutant volatile organic compounds in the soil at the site and in the groundwater beneath the site.

Based on available information, the source of the contamination is attributable to historic leakage and spillage of industrial solvents and petroleum products on the subject property. It is not known if off-site sources contribute to the groundwater contamination detected on-site.

AMBIENT AIR PHOTOIONIZA TION ANAL YSIS USING THE PHOTOVAC TIP II

SUMMARY OF ANAL YTICAL METHOD

Air samples are taken with a direct reading Photovac TIP II photoionization detector. Continuous sampling of ambient air, at a rate of approximately 275 ml/min., is accomplished by a positive displacement pump. Detection occurs as the sample is drawn through a high energy, ultraviolet photoionization detector (PID) to ionize a small portion of the introduced sample. The instrument is equipped with a lamp with an ionizing energy of 10.6 eV which will detect most organic compounds with an ionization potential of less than 10.6 eV. The

^process of ionization is initiated by the adsorption of a high energy photon by a molecule of the sample vapor in the ionization chamber. If the molecule's ionization potential is equal to or less than the photon energy (hv), a positive ion and an electron is formed.

R + hv ~> R+ + e"

Ion formation occurs in the electrical field between the collector electrode and the jet in the ionization chamber of the detector. Ions and electrons that reach the electrodes contribute to a small ionization current that is measured with the electrometer of the instrument.

The amount of ions that reach the electrode will be proportional to the concentration of the ionizable molecules within the linear range of the detector. The detector response is displayed on the digital readout with a range of 0-2000 PPm and a resolution of 0.1 parts per million. Using a 10.6 eV lamp, the range of detectable compounds encompasses a very large number of solvent materials and some important pollutant species including benzene, vinyl chloride, trichloroethylene, m-xylene, acetone, 1,2-dichlorobenzene, methyl ethyl ketone .and toluene.

Sampling environmental air is accomplished with the Photovac TIP II by (1) headspace analysis of sample containers, or (2) analysis of ambient air near the target media.

AMBIENT AIR PHOTOIONIZA TION ANAL YSIS

USING THEPHOTOVAC TIP II

SUMMARY OF SAMPLING PROCEDURE

1. CALIBRATE THE INSTRUMENT ACCORDING TO THE INSTRUCTIONS PROVIDED IN SECTION 4 OF THE TIP II USER'S MANUAL RECORD CALIBRATION DATA AND BACKGROUND LEVELS IN THE SPACES PROVIDED ON THE PHOTOIONIZATION DETECTOR HELD DATA SHEET.

2. SAMPLE JAR HEADSPACE ANALYSIS

A. FILL AN 8 OR 16-OUNCE GLASS JAR APPROXIMATELY ONE-HALF FULL WITH THE SOIL TO BE SCREENED, COVER WITH A DOUBLE ALUMINUM FOIL SEAL AND SCREW-ON CAP.

B. SAMPLES SHOULD BE SCREENED AT ROOM TEMPERATURE. IN COLD WEATHER, WARM SAMPLES TO APPROXIMATELY 70 DEGREES FAHRENHEIT USING YOUR AUTOMOBILE HEATER OR BY PLACING ON A WARM AUTOMOBILE HOOD.

C. RECORD THE BACKGROUND AMBIENT AIR READING.

D. SHAKE SAMPLE JAR VIGOROUSLY FOR APPROXIMATELY 10 SECONDS TO RELEASE VOLATILE COMPOUNDS.

E. REMOVE CAP FROM JAR AND PUNCTURE A SMALL HOLE IN THE ALUMINUM FOIL INSERT THE TEFLON PROBE INTO THE HOLE AND RECORD THE HIGHEST READING FROM THE LCD DISPLAY. SUBTRACT THE BACKGROUND LEVEL FROM THE READING TO OBTAIN THE ACTUAL LEVEL.

F. ALLOW THE INSTRUMENT TO RETURN TO THE BACKGROUND READING. IF THIS TAKES TO LONG, ALLOW THE INSTRUMENT TO RETURN TO A READING LESS THAN 10 AND RECORD THE READING. THIS READING IS THE NEW BACKGROUND LEVEL. ANALYZE THE NEXT SAMPLE AND SUBTRACT THE NEW BACKGROUND LEVEL TO OBTAIN THE ACTUAL LEVEL OF TOTAL IONIZABLE COMPOUNDS.

3. IN-SITU SOIL HEADSPACE ANALYSIS ( i.e. PIT WALLS, BACKHOE BUCKETS, ETC.)

A. SCREEN SOILS WITH THE PHOTOIONIZATION DETECTOR IMMEDIATELY AFTER THEY ARE EXPOSED. IN A TEST PIT OR TANK EXCAVATION, SCRAPE THE TOP FEW INCHES OF SOIL PRIOR TO SCREENING TO EXPOSE REPRESENTATIVE SOIL

. B. USING A STICK OR SIMILAR IMPLEMENT, POKE A HOLE 4 TO 6-INCHES DEEP IN THE SOIL TO BE SCREENED. REAM AND PACK THE HOLE USING A CIRCULAR MOTION.

C. IMMEDIATELY INSERT THE PROBE 2 TO 3-INCHES INTO THE HOLE, TAKING CARE NOT TO ASPIRATE ANY SOIL

D. RECORD THE BACKGROUND AMBIENT AIR READING.

E. RECORD THE HIGHEST READING FROM THE LCD DISPLAY.

F. ALLOW THE INSTRUMENT TO RETURN TO THE BACKGROUND READING. IF THIS TAKES TOO LONG, ALLOW THE INSTRUMENT TO RETURN TO A READING LESS THAN 10 AND RECORD THE READING. THIS READING IS THE NEW BACKGROUND LEVEL. ANALYZE THE NEXT SAMPLE AND SUBTRACT THE NEW BACKGROUND LEVEL TO OBTAIN THE ACTUAL LEVEL OF TOTAL IONIZABLE COMPOUNDS.

QC/QA STATEMENT

All samples received by this laboratory are logged in only after proper chain of custody information is received by the lab personnel from the field sampling personnel or the client delivery person. Chain of custody documents are kept with the laboratory data sheets until such time as the data sheets become part of the permanent project file. Samples are kept for one month if until protocol permits or until the client deems they are no longer needed. Hazardous samples are either returned to the client with chain of custody documentation or disposed of by a licensed disposal firm.

All the data included in this report was produced by procedures described in "Standard Methods for Examination of Water and Wastewater" or EPA approved methodology. All raw data was collected and placed in individual analysts' notebooks before being transferred to final data sheets and subsequently onto final report forms.. Each individual analytical instrument is standardized with standard chemicals traceable to the National Bureau of Standards. Standards are run at the commencement of each individual parameter run and after each set of six samples and at the end of each run. In the case of the Gas Chromatograph/Mass Spectrometer, the instrument is autotuned prior to running any sample or standard. The autotuning must fall within specified limits before any analysis may proceed. Each chemical identified by the mass spectrometer during a run is quantified only after the appropriate standards. All sample results are calculated using linear regression (least square approximation) standard calibration lines or curves.

All sample data is checked by the designated QA/QC person and further checked by the laboratory manager before being distributed for publication.

£' This letter is to advise you that during the excavation of the test pits at the site of the proposed new building on 1 September 1987, we encountered soil and groundwater that appear to be contaminated with hazardous materials.

As you are aware, five backhoe test pits were excavated at the site prior to the decision to terminate the exploration work. The test pits were excavated by David Channcey. Inc. and logged

sampled by Mr. Mark Brownstein of our staff. A print of the survey plan showing the approximate location of the test

pits and copies of the field logs are enclosed.

Soils and groundwater in test pit TP-5. appeared to be highly contaminated with fuel oil, and an abandoned, reportedly empty, fuel oil tardc was subsequently located immediately adjacent to the excavation. In test pit TP-4, when excavating to a three foot depth, a strong chemical odor was noted. Plant personnel

- 1 Present during the excavation said the odor appeared to be that of perchloroethylene. and indicated that the truck body that had

l&V been moved to allow excavation of the test pit was used for ^^^.S^S^storage of that product. They also indicated that the remaining ^§1 ll^adjacent truck bodies were used to store paint products and

Wfegvtoluene. and reportedly at some time in the recent past a drum toluene had been ruptured and assumedly spilled.

itJpon:.encountering the apparent perchloroethylene contamination |we^|decided to terminated the exploration work due to the ^potential health hazard. The test pits were backfilled with the excavated • soils.

. "y.:.

It should be noted that both the perchlorethylene and toluene classified as hazardous materials by the Federal

£#3s3^7Envirohmehtal. Protection Agency and that fuel oil is considered hazardous material by the Commonwealth of Massachusetts.

Wj^4.v...„ ^therefore recommend that you advise Precise Engineering, j^^gjlnc;;.;- of the above findings so that they can take action to

^^^^riotify the appropriate environmental agencies of the apparent . ^^S^^xpresence of this contamination at the site and initiate action

determine the character and extent of the contamination and any containment or clean up requirements. Haley & Aldrich. Inc. has the expertise to conduct' such studies and would be pleased to assist Precise Engineering. Inc. if they so desire.

With regard to the continuing of the geotechnical exploration work, in view of the apparent presence of hazardous materials, our company safety regulations require that we prepare a Health and Safety Plan prior to resuming exploration at the site. This involves determining what known or likely contaminants may be

'h;-.;*-:. present in the soil-water system and providing field personnel with appropriate, means of detection', safety equipment, and taking .appropriate precautions to avoid accidental exposure.

We will await the results of your discussion with the owner concerning how he wishes to proceed. We will be pleased to proceed with the geotechnical work or provide assistance with environmental studies if so authorized

^syou_know, on September 1, .1987, several persons from DufreanW-Heiifyi ic., and Haley & Aldrich, Inc., were at your plant site in East''

^ ;. Bridgewater for the purpose of topographic survey and analysing soil test pits. The information will be used for the design of a new 1001 x 120 1 building.

During the soils exploration, two persumably contaminated soil areas were uncovered. The attached Haley & Aldrich. September 3rd letter explains the events. It is your obligation to contact the proper environmental agencies.

We recommend you contact an environmental consultant qualified to assist you in the clean-up process. Dufreene-Henry cannot assist you directly since we lack recent experience in the hazardous waste ficJtd and our liability insurance limits do not permit us tc do any worX involving hazardous waste.

We recommend three possible consultants who could help you, although others do exist. They are as follows:

Haley & Aldrich, Cambridge , MA 492-6460 IEP, Waltham, MA 890-4516 GHR Engineering Associates, New Bedford, MA 995-5136
