Malvern TCE

January 2000 Fact Sheet

Construction of Waterline Begins

Construction of the waterline is now underway in Hillbrook Circle. During the week of January 10, 2000, contractors began work by digging a trench. The trench is about two feet wide and will extend along the road in Hillbrook Circle. Eight inch pipe was also delivered. This pipe will be placed in the trench to carry water from the water main on Conestoga Road into the Hillbrook Circle residences.

The United States Environmental Protection Agency (USEPA) reached a settlement with the Chemclene Site Defense Group (CSDG) who have agreed to fund the project. CSDG hired the Philadelphia Suburban Water Company to construct the waterline.

The construction of this phase of the water main will take about six weeks. Once the line is installed, CSDG will hire a local plumber to connect the individual residences to the line. As a part of the hook up plan, private wells will have to abandoned. This process involves a CSDG contractor closing the well and disconnecting it from the home water system. In addition, the carbon filters that have been providing clean water to the Hillbrook Circle homes will be removed. The entire project is expected to be completed during the Spring of 2000.

Future Work

The settlement between USEPA and the CSDG also requires the CSDG to design and conduct the cleanup of other areas of the site. The following actions are required in addition to the waterline installation:

Main Plant Area Soils
Installation of a cap to prevent direct contact with contaminated soils at the Main Plant and to reduce the potential migration of these contaminants to the groundwater
Main Plant Area Groundwater Plume
Withdrawal and treatment of groundwater via air stripping followed by carbon adsorption or ultraviolet oxidation; subsequent injection of treated water back into the ground via wells.
Former Disposal Area/Mounded Area Soils
Excavation, off-site treatment and disposal of contaminated soils to reduce the migration of contaminants in these soils to groundwater.
Former Disposal Area/Mounded Area Groundwater
Implementation of a natural attenuation program to monitor reduction of contaminant concentrations in groundwater.

The CSDG will hire a design consultant to prepare the design plans for the project. The design will take approximately 12 months to complete. Once the design is approved the remainder of the cleanup activities will begin.

Ongoing Activities

In addition to the above activities, Chemclene Corporation is conducting certain cleanup actions at the Main Plant Area of the Chemclene property. Some of the actions are part of the USEPA’s November 1997 Record of Decision and other activities result from the fire that struck the main building of the facility in August 1999. These actions include:

TAG Grant Available

As part of the Superfund community relations program, EPA provides Technical Assistant Grants (TAGs) of up to $50,000. The TAG program enables citizens residing near a site to hire a technical expert to review and interpret site reports generated by EPA or other parties. Only one group per site can receive a TAG, so EPA urges local residents and groups to join together to apply. For more information on how to apply for a TAG, contact Amelia Libertz, EPA TAG Coordinator, at 215-814-5522.

The CSDG is a group of 36 “Potentially Responsible Parties” that EPA believes generated waste materials and/or transported those materials to Chemclene Corporation for recycling. Improper handling and storage of the waste resulted in contamination of soil and local groundwater at the site. Under the Superfund Law, the owners/operators of a site, the parties that generated waste materials, and the parties that transported the waste materials to the site are held responsible for the cleanup.
A cover placed over soil to prevent exposure to soil which also prevents rainwater from passing through the soil. The cap can be constructed of man made material.
Record of Decision (ROD)
A document that announces and explains EPA’s selected cleanup method(s). The ROD is based on information gathered during the remedial investigation and feasibility study and on comments received during the public comment period.
Responsible Parties
Present or former owners or operators of the site; companies/persons who arranged for treatment and/or disposal of hazardous substances at the site; or companies/persons who accepted hazardous substances for transport to the site for treatment or disposal. Whenever possible, through administrative and legal actions, EPA requires the responsible parties to clean up hazardous waste sites they have contaminated.
