- EPA issued its third five-year review report for the site in September 2012. The review found that the current remedy for the site is still protective of human health and the environment. It did include some future recommendations for the Site. Another five-year review will be due in 2017.
- The site was deleted from the National Priorities List of most hazardous waste sites in March 2004.
- The groundwater monitoring system is being operated by the current occupant of the property – Metal Masters.
- From 1952 until 1969 Tyler Refrigeration was located on three acres in Smyrna, DE, where the company used solvents to degrease and clean refrigeration equipment.
- Spent solvents, paint wastes and sludge were dumped into two unlined disposal pits.
- In the 1970s Clark Equipment Company excavated the pits to a depth of 20 feet, capped them with six inches of topsoil and planted vegetation.
- The site is now occupied by Metal Masters, a company that formerly manufactured kitchen equipment on site. Most of the old pits’ surfaces have been paved.
- Since 1977, trichloroethylene (TCE) and trichloroethane (TCA), both solvents have been found in Smyrna’s municipal wells, and the Tyler pit has been identified as the likely contributor to this pollution, although there may have been other sources.
NPL Listing History
- Clark Equipment company signed an agreement with the EPA to investigate contamination related to the disposal pits in 1991. The investigation revealed that the groundwater was contaminated with volatile organic compounds and a pesticide, but that contamination did not appear to be related to the former disposal pits.
- In January 1995, the Delaware Department of Natural Resources and Environmental Control (DNREC) issued a consent decree to Metal Masters to perform a remedial investigation to identify the source and extent of contamination.
- In October 1995, DNREC issued a final plan of remedial action which identified the probable source area of the VOC contamination on the Metal Masters property, however, this plan concluded that this VOC contamination was not at a level that would pose an unacceptable risk to human health or the environment.
- EPA issued a “No Action” Record of Decision (ROD) for the site, meaning that the remedy for the site was to monitor the groundwater.
- In 2002, EPA conducted a five-year review of the site and confirmed that the remedy is protective and later that year, the agency issued a final close-out report.
- The site was deleted from the National Priorities List of most hazardous waste sites in the country in 2004.
- A second five-year review report was issued in September 2007, finding that the remedy for the site was still protective.
- Since 1977 trichloroethylene (TCE) and trichloroethane (TCA) were detected in Smyrna’s municipal wells.
- Elevated levels of toluene, 1,1-dichloroethane and TCA were found in the soil taken from around the pit area.
- Groundwater in the pit area had elevated levels of TCA.
- Contaminant descriptions and associated risk factors are available at: (ATSDR web site).
