Redevelopment at the Site

From 1859 until 1948, the Dover Gas Light Company in Dover, Delaware, processed coal to produce gas for use in street lamps in Dover. Site operators buried process materials containing coal tar residues at the 23-acre Dover Gas Light Co. site, contaminating soil and ground water. In 1989, EPA placed the site on the National Priorities List (NPL). The site’s potentially responsible parties (PRPs) have conducted cleanup activities under the oversight of EPA and the Delaware Department of Natural Resources and Environmental Control since 1989. These activities include removing and treating contaminated soil, treating contaminated groundwater and constructing a cap over the site. Today, the cap over the 1-acre site serves as a paved parking lot for the adjacent Victrola Museum.
