Drycleaner Site Profiles
Scotch Cleaners, Topeka, Kansas
Description
|
A soil gas survey at a building in Topeka showed elevated levels of PCE and TCE in the soil gas. Subsequent investigations led to the Scotch Cleaners site as the source. Specifically along the sewer line exiting the building. Remediation Status: In active remediation |
