Are drinking water intake portals downstream from the site. All the way to the Delaware Bay?

As a part of the investigations, Evergreen conducted a well search including field reconnaissance within a one-mile radius of the Site using Pennsylvania’s Groundwater Information System (PaGWIS) and PADEP’s eMapPA GIS mapping tool. Search results did not identify potable water supply wells in the area. We also conducted a search of surface water intakes from the Schuylkill River within one mile of the Site, and the Philadelphia Water Department did not identify any surface water intake portals within one mile in its 2010 “Schuylkill River Hydrology and Consumptive Use Report.” For reference, the search radius for potable groundwater or surface water is typically ¼ to ½ mile from a Site, but Evergreen completed a one-mile search as part of the remedial investigation activities for this Site.
