• Former Wilmington Ford, 275 Main Street, RTN 3-3958
  The former Wilmington Ford property is a 4.8-acre parcel of land that was developed for automotive sales and maintenance in 1967. The property is currently a used car sales and service outlet. Initial investigations conducted on the property in 1990 identified soil and groundwater contamination with solvents and petroleum including: benzene, toluene, xylenes, tetrachloroethylene, 1,1,1-trichloroethane, 1,1-dichloroethane and 1,2-dichloroethylene. These chemicals were found in the vicinity of the leach field and a former 2,000-gallon waste oil underground storage tank excavated in 1992. Over 750 yards of petroleum and solvent contaminated soils were excavated and removed from the leach field and former waste oil tank area during tank removal activities in 1992 and cleanup actions conducted in 1995 and 1997. Twelve inches of free oil product was noted in a monitoring well adjacent to the former waste oil tank area in 1992. A groundwater sample collected from this monitoring well, KOW-1, also found 192 ug/l PCE. During removal of the former waste oil tank, over 1250 gallons of an oil/water mixture was pumped from the excavation. The site transitioned to a Tier II site on 8/14/96 and a Tier II extension was received by DEP on 6/8/99. The site is currently in compliance with the Massachusetts Contingency Plan.

• Amerada Hess Service Station, 273 Main Street, RTN 3-2889
  An Amerada Hess service station is located on a rectangular parcel of land comprising 40,000 square feet. A station building is located in the central portion of the site. No auto repair services are provided and no service bays are located on the property. The property has on-site septic and a municipal water supply and was first issued a permit for underground storage tanks of gasoline in 1965. A 1991 Phase I report reported only low levels of gasoline-related compounds in three on-site monitoring wells. No chlorinated volatile organic compounds were detected in any of the site wells. During tank removal activities in 1991, several small holes were observed in one of the underground storage tanks used for gasoline. Approximately 40 tons of petroleum contaminated soils were excavated and transported to an asphalt recycling facility. The site was Tier Classified on 7/28/97 as a Tier II disposal site.

• Former BP Service Station, 342 Main Street, RTN 3-2635
  A Gibbs gasoline sales station (formerly BP) currently occupies the property. A Notice of Responsibility was issued to BP in January 1990 based on the detection of gasoline and fuel oil-related petroleum hydrocarbons in soil and groundwater. A second Notice of Responsibility was issued to BP on January 30, 1996, based on the detection of trichloroethylene (TCE) in soil and groundwater at the site. The Notice of Responsibility directed BP to conduct an Immediate Response Action to evaluate the condition of Substantial Release Migration relative to the discovery of 37 ppm of TCE in the Zone II wellhead protection area. BP submitted an Immediate Response Action Completion Statement asserting that the property at 315-319 Main Street, RTN 3-14811, is the probable source of the chlorinated volatile organics contamination on the BP site. On June 6, 1996, BP submitted a Downgradient Property Status opinion for the chlorinated volatile organic compounds present in groundwater. Between 1990 and 1997, soil and groundwater investigations were conducted at the site by BP under a Waiver of Approvals granted by DEP in 1990 and subsequent Tier II extensions filed in 1995, 1996, and 1997.

On January 2, 1998, BP submitted a Class C Response Action Outcome for petroleum contamination remaining in soil and groundwater at the site. The Class C Response Action Outcome asserts that a Temporary Solution has been achieved because all Substantial Hazards have been eliminated relative to petroleum.

• JJT Realty Trust, 315-319 Main Street, RTN 3-14811
  On February 7, 1997, DEP was notified of the presence of elevated concentrations of chlorinated volatile organic compounds including TCE and PCE in groundwater samples collected from on-site monitoring wells. A Notice of Responsibility was issued by DEP on 5/19/97 to the estate of Marion Epstein requiring the performance of an Immediate Response Action to evaluate the extent, magnitude, and migration potential of the contaminant plume. The plan was conditionally approved by DEP on August 12, 1997. The work completed found that the likely source of contamination was near a former dumpster enclosure in the central portion of the site between building #1 (JJT) and Building #2 (former Double D Design). Groundwater samples collected from deep overburden wells at this location in November 1997 exhibited the highest levels of contamination at the site, over 400 mg/l of TCE. PCE was also found in the deep overburden wells at over 5 ppm.

Site investigations and response actions are currently being conducted at the site under a Tier 1C Permit issued by DEP on October 5, 1998. Reports submitted by the environmental consultants for this site concluded that contaminant concentrations in soil gas beneath building #1 did not pose an Imminent Hazard to building occupants. Based upon these findings, an IRA Completion Report was submitted to DEP on December 3, 1998.

On July 23, 1999, DEP issued another Notice of the Need to Conduct an IRA to 315 Main Street Realty Trust based upon concerns for the Zone II wellhead protection area and the need for expedited response actions. An IRA plan was submitted on July 31, 1999, and conditionally approved by DEP on August 31, 1999. The Immediate Response Action plan calls for the installation of additional shallow and deep groundwater recovery wells, the collection of additional groundwater data, and the performance of a potassium permanganate pilot test during the Spring of 2000 for cleaning up the dumpster source area.

• Exxon Facility, 205 Main Street, RTN 3-5644
  Gasoline contaminated soil and groundwater was first reported to DEP in a Phase I report completed in 1986 documenting contamination found during an underground storage tank replacement. Additional contamination was discovered during a series of underground storage tank replacements in 1994. A Tier 1C permit was granted for the site on 10/22/96, and 121 tons of petroleum contaminated soil was removed from the site in 1998 under a DEP approved remedial plan. The remedial plan also proposed to inject an additive into the subsurface to elevate the concentration of dissolved oxygen to promote biodegradation of the residual petroleum contaminated soil and groundwater. It should be noted that one shallow on-site groundwater monitoring well was found to contain PCE at 34 ug/l (note 1000ug/l = 1 mg/l). A Notification of Delay in Submittal of the Phase II report was received by DEP on 4/27/99.

• Former Sweetheart Cup Co., 1 Burlington Avenue, RTN 3-15247
  This site is an approximate 30-acre parcel of land occupied by an office building and two large slab-on-grade warehouses used for the manufacture of plastic and plastic foam products from 1965 to 1990. DEP was notified of a release of chlorinated volatile organic compounds to groundwater on 6/26/97. Trichloroethylene and tetrachloroethylene as well as several other associated chlorinated compounds were found at concentrations exceeding the groundwater standards established in the Massachusetts Contingency Plan. TCE was found in one well at 283 ug/l, and PCE at 97 ug/l. In March 1997, monitoring well P-2 identified methyl tertiary butyl ether at 13 ug/l. The Phase I report suggested that the source of the chlorinated VOCs is most likely from solvent releases used to clean machinery parts. The contaminated rinse waters had then entered the subsurface through floor drains and sumps. Handex of New England has recently installed a soil vapor extraction system and an air sparging system in the area of the chlorinated VOC contamination under a clean-up plan submitted to DEP on 7/29/97. A Tier 1C permit was subsequently issued to Sweetheart Cup on 11/19/98.

• Former Gasoline Station, 103 Main Street, RTN 3-4022
  This property was the location of a former gasoline filling and service station. In 1991, three underground storage tanks were excavated and removed from the site. Thirty yards of petroleum contaminated soil were stockpiled on-site and transported to Brox in Dracut in 1992 for recycling. Three shallow monitoring wells installed on the property in 1991 showed groundwater contamination with the common gasoline compounds, benzene, toluene, ethyl benzene and xylenes totaling up to 33.7 mg/l. MtBE was also found at concentrations ranging from 51 ug/l to 1500 ug/l. Several chlorinated VOCs were also found in one well at trace to low concentrations including PCE at 11 ug/l. A site assessment report completed in 1994 found the direction of groundwater flow to be east southeasterly towards Main Street and Lubbers Brook. The estate of the property owner notified DEP that they do not have the financial capacity to conduct further response actions. The site is currently listed as a Default 1B site.

• Joe Barry's Oil, Inc., 312 Main Street, RTN 3-15515
  The subject property is a 0.68-acre parcel of land that is the site of a bulk fuel storage facility. A permit for gasoline storage was first issued in 1922. In 1953, an additional 80,000 gallons of fuel storage was permitted. A Notice of Responsibility was issued by DEP on 7/18/96 for 2.1 feet of free-phase petroleum product in an on-site monitoring well. A report on file indicates that as part of an underground storage tank removal effort, 1,945 gallons of an oil/water mixture was pumped from the excavation and 200 tons of soil was transported to AMREC in Charlton, Mass., for asphalt batching. Several on-site monitoring wells were reported with free-phase oil product floating on groundwater. The site was classified as a Tier II site on 6/29/97, and is currently listed as being in Phase II of the MCP process. Nine underground storage tanks were removed from the northwest portion of the site in June 1999 as part of a clean-up plan submitted to DEP on 9/18/98. Two oil-skimming devices are presently operating at the site to recover residual free phase petroleum product present in the subsurface. No chlorinated VOCs or MtBE were reported in site assessment data.

• Fred's Service Station, 324 Main Street, RTN 3-0776
  The property is a 19,000 square foot plot of land housing Fred's Service Station. Prior to Fred's, established in 1978, the facility was owned by Louis Elfman and was operated as a home oil heating center, fuel dispensary terminal, and gas station since the mid-1920s. On January 12, 1987 a Notice of Responsibility was issued by DEP for oil discovered during a tank excavation. The site was Tier classified in November 1996 as a Tier II site, and is currently listed as being in Phase II of the MCP process. A clean-up plan was submitted to DEP on November 11, 1998, and over three hundred tons of petroleum contaminated soil was excavated from the site and transported to a recycling facility.

• Former Service Station, 101 Main Street, RTN 3-1916
  This site is the location of a former gasoline filling station. Information obtained in the limited site file indicates that in 1988 a total of five test borings were advanced and completed as groundwater monitoring wells. Groundwater contamination with gasoline-related compounds was found up to 16,200 ug/l in on-site monitoring wells. No chlorinated VOCs were observed in the groundwater analyses. The property is not in compliance with the MCP, and is currently listed as a Default 1B site.

• Silver Lake Pharmacy, 52 Main Street, RTN 3-17721
  A notification was made to DEP on 8/19/98, resulting from a soil sample found to have exceeded the applicable soil standard, collected during the removal of an above-ground fuel oil storage tank. No further information was listed in the site file and the site is currently in non-compliance with the MCP and is listed as a Default 1B site.
