Beaverdam Road Landfill Permeable Reactive Barrier

The Beaverdam Road Landfill (BDRLF) site is another site BMT characterized for the U.S.

The Beaverdam Road Landfill (BDRLF) site is another site BMT characterized for the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) at the Beltsville Agricultural Research Center (BARC) in Maryland.

BMT led a Remedial Investigation/Feasibility Study that included site investigation, development of a Site Screening Process, ecological risk assessment, human health risk assessment, and feasibility study to evaluate remedial options.

BMT completed soil, surface water, sediment, and groundwater sampling. Groundwater samples were collected with Geoprobe® direct push wells. The selected remedy was the installation of a permeable reactive barrier (PRB) to create the conditions necessary for the microbially mediated degradation of trichloroethene in groundwater.

PRBs are a developing remediation technology which employs an underground structure to host a bio-film membrane to capture and break down contaminants as they pass through the wall. Treated groundwater is passively discharged via natural groundwater flow.

BMT completed a comprehensive Remedial Design/Remedial Action Work Plan which was approved EPA Region III. BMT performed routine monitoring to evaluate PRB performance and achievement of applicable or relevant and appropriate requirements developed during the remedial investigation and feasibility study.
