1.1.2.1 Location
38.012958 N

The coordinates above are for the Acme Well. This is not considered the Site source, but is being used as a reference for documentation purposes.
1.1.2.2 Description of Threat
Tetrachloroethylene (perchloroethylene, "PCE","perc" or tetrachlorethene)
Tetrachloroethylene is a manufactured chemical used for dry cleaning and metal degreasing. It is also known as perchloroethylene or "perk"
The EPA maximum contaminant level for the amount of tetrachloroethylene in a public water drinking supply is 5 micrograms tetrachloroethylene per liter of water (0.005 mg/L).
The Occupational Safety and Health Administration (OSHA) has set a limit of 100 parts per million in air for an 8-hour workday over a 40-hour work week.
The National Institute for Occupational Safety and Health (NIOSH) recommends that tetrachloroethylene be handled as a potential carcinogen and recommends that levels in the workplace air should be as low as possible.
For more information on tetrachloroethylene, please see the "DOCUMENTS" section of the main website.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
A removal Site evaluation as described in 40 CFR 300.410 is complete. A formal Site Inspection as described in 40 CFR 300.420 is currently underway. This assessment is being performed by VDEQ.
As noted in POLREP #9, the site would be re-evaluated . In August 2013, OSC Francisco J. Cruz was notified that a previously vacant property was going to be occupied. A December 2012 sampling event indicated that PCE levels in the private well of the home were elevated and posed a human health threat if the water were to be consumed.

2.1.1 Narrative
On September 10, 2013, a memo entitled "Request for Exemption from the 12-Month Statutory Limit for a Removal Action at the Louisa Acme Well Site in Louisa, Louisa County, Virginia" ("Action Memo") was signed to exempt the current Removal Action from the 12-Month limit on conducting a Removal Action. The Action Memo calls for the home to be connected to the public water system in order mitigate the immediate threat posed by PCE in the private drinking water well.
On October 18, 2013, EPA and ERRS mobilized to the site to begin boring operations in order to run the public water line from across the street of the affected home. The Louisa County Water Authority (LCWA) and their contractors located the water line and dug a trench on the affected property in order to install the water meter. ERRS, through their subcontractor, bored a line under Jefferson Highway in order to connect the home to the waterline. Following the boring operations, LCWA ran a pipe from the public water line to the area near the water meter.
On October 21, 2013, ERRS, through their plumbing subcontractor, began running piping from the water meter to the house. A trench was dug between the two points to allow for access to the home and meter. Once the piping was installed, the trench was left open to allow for inspection by Louisa County authorities. Following the inspection, the trench was backfilled and the area was seeded to allow for grass growth.
On October 22, 2013, the piping work was completed, and the subcontractor completed restoration operations on the property.
2.1.2 Response Actions to Date
Previous response actions are summarized in Polreps #1-#8.
As of October 22, 2013, the affected home has access to the public water system.
