The colored areas on the map below have been identified in past studies as having an existing or potential pollution problem related to on-site sewage disposal. These areas had been destined for off-site treatment. More recently, the areas of concern are being refined, and through communications with the DEEP, the WPCC and its consultants were able to take a fresh look at the study area, and further investigate which neighborhoods are truly in need of off-site wastewater treatment and which neighborhoods can support continued on-site septic systems with proper management.
