Due to growing concern of elevated levels of metals precipitating into groundwater due to acid mine drainage, EPA's Remedial Branch performed a water sampling event in April, 2010. Initial samples were taken in areas believed to have the highest exceedances of metals concentrations with other residences to be sampled shortly thereafter. The samples were taken at the well head outside of the homes and at the water tap inside of the residences. EPA's Remedial Branch and Technical Services Section have analyzed results and determined that homes with a functional water filtration system or water softening device have metal contaminants below risk levels. However, some residences without these devices were determined to have manganese levels that exceed MCLs. Concentrations approaching 10,000 ppb were recorded. OSC Byrd executed an emergency action providing affected residents with potable water based on this information.
