Bioremediation

Bioremediation involves the use of bacteria or plants to eliminate or neutralize contaminants found in water or soil. WESTON has been conducting bioremediation project for the past 10 years, including:

Norfolk State University—WESTON successfully conducted on-site bioremediation of 6,000 yd3 of soil contaminated with TPH at concentrations as high as 18,000 ppm.

ARCO—WESTON completed a project for an ARCO petroleum site involving in situ vadose air zone bioremediation, bioventing, and air sparging.

Southern Maryland Wood Preservers—Implemented pilot-scale composting and land farming to treat soil contaminated with pentachlorophenol (PCP), creosote, polycyclic aromatic hydrocarbons (PAHs), dioxins, and nonaqueous-phase liquid (NAPL).

Southwestern Property Corporation—Performed a fast-track (8-week) bioremediation project to treat 5,000 yd3 of TPH-contaminated soil.

Industrial Client in Houston, TX—Performed fast-track installation of an in situ anaerobic bioremediation system, consisting of an alternating series of extraction and injection trenches, to treat groundwater contaminated with chlorinated solvents.
