EPA grants approval of cleanup measures for waste superfund site in Missouri

Installations of a multi-layered engineered cover and a system of new monitoring wells are among a series of key remedial actions that will best serve to protect groundwater resources and human health at the West Lake Landfill Superfund Site in Bridgeton, Missouri, according to a plan formally approved by EPA.

“We believe it is imperative to move ahead by placing a properly engineered cover on the landfill,” EPA Region 7 administrator John Askew said. “The cover would serve as a stable barrier to minimize future exposure to waste material, as the landfill currently has no such protective cap.”

The EPA’s design process also calls for the installation of a new system of monitoring wells around the site, and for long-term groundwater sampling to occur, with the results of all tests to be made available to the public.

The Agency’s next steps for West Lake Landfill will be to work closely with the site’s owners and responsible parties as they identify and secure the services of various contractors to develop specific engineering designs, construct the landfill cover, install the monitoring wells, and establish specific schedules and measures for sampling procedures and sharing test results.
