The South Dayton Dump and Landfill is a former disposal area for industrial and municipal waste. The site is approximately 80 acres and includes a 15-acre pond, as well as property now occupied by an operating asphalt plant and other businesses. Open burning, landfilling and storage of hazardous waste throughout its half-century operation has resulted in contamination of soil and portions of the ground water aquifer underlying the site, potentially threatening the adjacent Great Miami River. Soil contains metals that include lead, copper, mercury and other chemicals. Groundwater contamination is mainly organic chemicals such as tetrachloroethylene, vinyl chloride, and benzene. In 2006 the Agency and the potentially responsible parties (PRPs) signed an agreement for EPA to oversee the PRPs investigate the nature and extent of contamination, determine risks posed by the site to human health and the environment, and develop cleanup options.

Based on sampling of groundwater, soil gas, sub-slab air, and indoor air, EPA has documented a completed exposure pathway for vapor intrusion at the SDDL Site. Vapor intrusion occurs when chemicals in landfill materials and ground water give off gases that can rise up through the soil and seep into buildings through foundations. What You Should Know About Vapor Intrusion (PDF) (2pp, 84K).
In order to reduce the sub-slab and indoor levels of TCE and methane, EPA issued an Action Memo in October, 2012, that required the PRPs to install sub-slab depressurization systems at several on-site buildings. These systems, similar to radon mitigation systems, have been installed in several buildings along Dryden Road and are drawing TCE, methane and other vapors out of the soil under the buildings and vent them outside.
