Info

Site Conditions • Past maintenance activities at Dover AFB resulted in release <strong>of</strong> chlorinated solvents to the environment. • <strong>Source</strong> area in in soil beneath building foundation. • Contaminated soil is inaccessible by conventional remedial technologies. • Groundwater plume extends ≈ 1 mile downgradient.
Site Conditions (continued) • Limited soil data/source delineation. • Soil concentrations: TCE up to 280,000 µg/kg • Groundwater concentrations: TCE up to 21,000 µg/L
