Letter Health Consultation: Soil Lead Data Evaluation, Ottawa Lead Site, Ottawa, Putnam County, Ohio. EPA Facility ID: OHN000510386, October 21, 2010.

摘要

The Ohio EPA's investigation of plant records revealed documented disposal of waste glass occurred in Ottawa from the 1940s to the early 1990s and that waste glass from the former GTE plant has been disposed or used as fill at a number of locations in and around the village of Ottawa in Putnam County, Ohio. Most of the waste was disposed of at what are now private residences. In April 2009, the U.S. EPA Region 5 and the Ohio EPA performed a limited assessment on four residential properties in Ottawa where waste from the GTE/Sylvania/Philips operation had been disposed of. The sampling results showed elevated lead levels in surface soil at one of four properties (U.S.EPA 2009). Due to the presence of lead detected in these wastes, federal and state agencies wanted to conduct additional assessments on other lots in and around Ottawa where industrial dumping may have occurred. In April 2010, the U.S. EPA performed additional testing at these other potentially impacted properties in Ottawa.
