Proposed Plan of Remedial Action

Soil at Operable Unit 4 (OU-4) was not impacted. OU-4 groundwater was impacted by ethylbenzene, 1,2,4-trimethylbenzene, xylene, and naphthalene.  Groundwater contamination migrated offsite to the northeast.  As the groundwater travels from the site, contamination reduces and does not impact any offsite drinking water wells.  Indoor air samples from Townhouses on Dodson Avenue do not indicate a risk from groundwater to indoor air.  The contamination at OU-4 will be addressed by groundwater monitoring, restricting OU-4 to commercial use, limiting groundwater use, and requiring soil/groundwater management plan during redevelopment.  

Details of the Proposed Plan are available online at www.nav.dnrec.delaware.gov/DEN3/.
