Description: AKA. Ed's Swamp. The MCWA received a Watershed Rehabilitation and Partnership Act grant in 1999 to construct wetlands in order to treat AMD problems in Mahanoy Creek. The Swamp is a four-acre wetland located upstream of the village of Gordon. Five to ten percent of water from the stream is diverted into the swamp where the pollutants can settle out before returning back to the stream. The Swamp is the first part of the four-part passive treatment project. In 2000, the group received a Growing Greener Grant to assess the effects of AMD and for possible remedial alternatives for abandoned mine lands in the watershed. In 2001, they received a CWA Section 319 Grant to expand the Swamp project and allow 750 to 1,500 gallons of water per minute to be treated. (PADEP WRAS 2000)
