Description: One of the oldest passive systems in the watershed. SR114 B&D passive systems were designed through a collaboration of Hedin Environmental and CDS Associates, Inc and were installed in 1995 to treat mine drainage emanating from an old deep mine on State Game Lands property. SR114B system consists of an ALD and settling pond, while the SR114D system consists of an ALD, settling pond, and 3 wetland cells. Once they reached the end of their design life, the B and the D systems were redesigned by BioMost, Inc and rebuilt by Spur Excavation, LLC in 2023.
