This decision document presents the interim remedial action for the Hereford Groundwater/Crossley Farm Site ('Site') in Huffs Church, Berks County, Pennsylvania. This interim remedy will provide point of entry treatment systems to the residents who are impacted by contamination from the Site and provide the potential for additional residential point of entry systems if needed in the area of the Site. The filter treatment units will be maintained and residential wells would be periodically montitored. Water pumped from the private wells would be passed through the treatment systems at the point of entry into the homes. Each typical treatment system would be composed of a prefilter to remove suspended solids, dual in-series activated-carbon units to remove VOCs, and an ultraviolet (UV) radiation unit to provide disinfection. Depending on the contaminants identified at specific residences, additional treatment components may be required, such as pH adjustment or a water-softening unit to remove manganese and iron. the activated carbon would be replaced on a period basis or when breakthrough is identified. Through the provision of these treatment systems, contaminant concentrations would be reduced to below the drinking water criteria.
