 Hockessin Groundwater Site

 

UPDATE:   The U.S. Environmental Protection Agency (EPA) announced on May 15, 2018 that the Hockessin Groundwater Site will be added to the National Priorities List (NPL). The NPL is EPA’s list of sites eligible for remedial action financed under the federal Superfund program. The proposed listing will allow EPA to use Superfund authority and resources to work with DNREC to help resolve groundwater concerns in the Hockessin area. EPA -- with support from DNREC, the Delaware Division of Public Health (DPH) and Artesian Water Company -- held a public meeting on the proposed listing of the Hockessin Groundwater Site to the NPL in Feb. 2018 at Hockessin Memorial Hall. For Federal Register notices and supporting documents for the site, please visit: http://www.epa.gov/superfund/current-npl-updates-new-proposed-npl-sites-and-new-npl-sites
