CONCRETE CITY SILT POND
2009 • 25 acres • Nanticoke & Hanover Township, Luzerne County, PA
During mining, wastewater from the mining process is often deposited into some sort of catchment. The Concrete City silt pond, located on the border of the City of Nanticoke and Hanover Township, is such a structure: the large basin holds a slurry comprised of water and fine sediments, including coal. Unfortunately, those minerals destroy water and soil quality, preventing natural ecological functioning and producing acid mine drainage. EC received a US EPA Brownfields Cleanup Grant in 2003 to support the site’s reclamation. Currently, the area will remain as open space.

In addition to the silt within the pond, large piles of silt material were scattered across the site.
Work involved removal of the silt material and grading.
Continued grading of the area.
The Concrete City reclamation included a pilot project using specialized compost for revegetation, supported by the Chesapeake Bay Foundation. Approximately 1,800 cubic yards of compost made from chicken poultry manure was delivered to the site, which was supplemented with additional compost from EC’s facility.
Hydroseeding was then done throughout the site.
