Health Assessment for Delaware Sand and Gravel Landfill National Priorities List (NPL) Site, New Castle County, Delaware, Region 3. CERCLIS No. DED000605972

摘要

The Delaware Sand & Gravel Landfill National Priority List site is in New Castle County, Delaware. The property is adjacent to the Army Creek Landfill NPL site, and remedial planning for both sites is being coordinated so that corrective measures are compatible and effective. Contaminants of principal concern are volatile organic compounds and heavy metals. The principal potential public health concern is for contaminated groundwater and its effect on a public water supply well field downgradient from the landfill sites. A groundwater recovery system, to date, has prevented potentially extensive contamination of the public water supply (well field); proposed remedial measures are expected to improve groundwater quality. The site, without remediation, is of potential health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects.
