Description: SR81 passive treatment system was originally designed by BioMost Inc and constructed in 2002 to address two acidic metal-bearing discharges through use of an anoxic limestone drain, settling pond, and aerobic wetland. The system was most recently rehabilitated in 2023 and was redesigned by BioMost, Inc and rebuilt by Spur Excavation, LLC. Rehabilitation involved expanding the ALD, expanding the constructed wetland, increasing use of the natural wetland, and cleaning treatment components of sludge and debris.
