NORTH SANITARY LANDFILL
Superfund Site Profile
The 102-acre North Sanitary Landfill (NSL) site is located in Dayton, Ohio. More than half of the area was used for landfilling industrial and municipal wastes into unlined former gravel pits. Five disposal areas have been identified. The site sits atop and within a federally designated, sole-source aquifer. Landfill operations contaminated soil and groundwater with hazardous chemicals. Many fires have also occurred on site. Residents with affected drinking water wells have been connected to the public water supply. Following immediate actions to protect human health and the environment, planning and negotiation efforts for the site’s long-term remedy are ongoing.
