Since 2002, we have installed nine passive treatment systems that use constructed wetlands for acid mine drainage remediation. Wetlands filter contaminants like iron and aluminum out of the water. Limestone is added to the system to oxidize metals, letting them fall to the bottom of a large settling pond where they are trapped and cannot flow into the main branch of the West Fork River. Cattails have also been used in these systems for natural water filtration.
In May 2012, bidding took place for a passive treatment system design for Site #6.
In June 2012, abnormally high electrical conductivity readings were found in and around the Lambert’s Run restoration site (Site #9). We contacted several individuals for assistance, but the cause was not determined.
