Abstract | The 3-acre Mid-Atlantic Wood Preservers (MAWP) site is a wood treatment facility in Harmans, Anne Arundel County, Maryland. Since 1974, the facility has been used for pressure treatment of lumber using chromate copper arsenate (CCA) as the wood preservative. However, offsite investigations by EPA in 1983 identified elevated levels of arsenic and chromium in ground water. The selected remedial action for the site includes excavating and stabilizing approximately 20 cubic yards of onsite soil contaminated with arsenic levels greater than 1,000 mg/kg (referred to as hot spots), followed by offsite disposal; capping the remaining soil with arsenic concentrations between 10 mg/kg and 1,000 mg/kg with an asphalt/concrete cap; constructing an enlarged and roofed drip pad which is consistent with new wood treating regulations; allowing natural attenuation to lower chromium levels in ground water; monitoring sediment, ground water, surface water, and air; and implementing institutional controls including deed restrictions. |
