The USEPA-selected remedy for the site, as outlined in the site's ROD, is intended to protect human health and the environment in the short and long term.
The site remedy generally consists of the following components:
Landfill: Limit access through installation of a fence, contain landfill constituents of concern (COCs) through installation of an impermeable cap, and remove landfill gases through operation of an active gas collection system that extracts landfill gases and COCs and thermally destroys them in an enclosed flare.
Groundwater: Monitor groundwater and restrict potable groundwater use in impacted areas; provide alternative sources of potable water in those areas; and monitor the natural attenuation of site COCs.
Monitored Natural Attenuation
As the COCs mix and move with the groundwater, they naturally age, dilute, breakdown and degrade. For example, 1,2-dichloroethane and acetone were once COCs at the site, but have since naturally degraded to the point that they are no longer of concern. An important part of the site remedy is to monitor this natural process.
