The South Dayton Dump and Landfill is a former disposal area for industrial and municipal waste. The site is approximately 80 acres and includes two 5-acre ponds used for disposal, as well as property now occupied by an operating asphalt plant and others. 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, and threatens the adjacent Great Miami River. Soil contains metals that include lead, copper, mercury and other chemicals. EPA proposed the site to the Superfund National Priority List in September 2004. The Agency is negotiating with potentially responsible parties for the investigation of the nature and extent of contamination.

As part of a vapor intrusion study, sub-slab and indoor air sampling was done at several Representatives of EPA sampled ground water, soil gas, sub-slab air and indoor air for vapor intrusion in areas of the landfill. 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. EPA did find that there is a level of exposure that may affect people’s health.
The chemicals of TCE (tricholoroethylene) and benzene were documented at higher levels at the site. TCE recorded higher levels in ground water, soil gas, sub-slab air and indoor ar. Levels of benzene were measured in indoor air. Methane was found in one non-residential property at an increased level. Levels of exposure are recommended to protect people’s health.
In order to reduce the sub-slab and indoor air levels of TCE and methane, EPA issued an Action Memo in October 2012, that requires the potentially responsible parties (PRPs), who may have contributed to the contamination, to install sub-slab depressurization systems at several on-site buildings. These systems are similar to radon mitigation systems and will draw TCE, methane and other vapors out of the soil under the buildings and vent them outside.
