2.1.1 Narrative
During a vapor intrusion assessment conducted in March 2015 by the EPA for the PCE Former Dry Cleaners Site, the EPA discovered another former dry cleaner site (PCE Chestnut Street) to the west of the PCE Former Dry Cleaners Site. The levels of PCE vapors found in buildings at the Site present a significant health threat due to inhalation hazards.
2.1.1.1 Current situation
Vapor intrusion sampling was conducted the weeks of July 13 and 20, 2015. The results of the sampling showed two properties with TCE vapors in the inside air higher than the TCE vapors in the subslab.
2.1.2 Response activities to date
On September 8 and 9, 2015, the EPA conducted an assessment of the two properties, with TCE vapors inside the property higher than the TCE vapors in the subslab.
13 East 4th Street
The property at 13 East 4th Street consists of three businesses on the main floor over a basement. Above the businesses are apartments that are not currently occupied. The businesses are a shoe cobbler, a barber shop, and a sign shop.
The basement has several open and closed containers of paint, varnishes and strippers from the sign company. No specific container was found with TCE as a listed ingredient. However, several containers were rusty and there were several boards and other debris hampering the ability to find all containers.
The Agency for Toxic Substances and Disease Registry (ATSDR) Toxicological Profile for Trichloroethylene (Update), U.S. Public Health Service, U.S. Department of Health and Human Services, Atlanta, GA 1997 states:
"Trichloroethylene is used in consumer products such as typewriter correction fluids, paint removers/strippers, adhesives, spot removers, and rug-cleaning fluids".
Therefore, the EPA will be requesting that the owner remove all containers from the basement that are no longer used. Then retesting of the indoor air will be done to determine if there is still TCE in the indoor air that exceeds EPA Removal Action Levels.
The EPA and START located areas where groundwater sampling will be conducted in October 2015.
The EPA also met with ERRS contractor. The ERRS contractor put out for bid four properties to install vapor mitigation systems. Three potential bidders met and conducted a walk-through of the four properties.

2.2 Planning
2.2.1 Anticipated activities for next reporting period
The EPA OSC is planning to conduct oversight of the installation of vapor mitigation systems in four properties. The EPA will be conducting a removal action at 500 Chestnut.
2.2.1.1 Planned Response Activities
The EPA will be collecting groundwater sampling the first week of October 2015. Groundwater sample results will be used to delineate the groundwater plume and to help locate source areas.
2.2.1.2 Next Steps
Continue to delineate groundwater plume and locate source areas, as well as collect additional vapor intrusion samples.

6.0 Source of Additional Information
PCE (Tetrachloroethylene):
• A man-made chemical that is widely used for dry cleaning clothes
• It evaporates easily into the air
• A colorless liquid with a mild, chloroform-like odor - has a sharp, sweet odor.
TCE (Trichloroethylene):
• Remove grease from fabricated metal parts and in the production of some textiles.
• PCE degrades to TCE under certain circumstances
• A colorless or blue liquid with a chloroform-like odor - has a sharp, sweet odor.
