Abstract	Jonathan Run is a tributary of Beech Creek that is impacted with acid rock containing fill material and clay during the construction of I-80 in central Pennsylvania. The acidic discharge of Jonathan Run contains white aluminum precipitates resulting in surface water quality degradation. Based on field research and subsurface investigations, preliminary suggestions are made for passive and active treatment systems involving flow elimination, mitigation and treatment. The active treatment alternative was selected for the major discharge while passive treatment was used for the less contaminated discharges. A conceptual design is presented consisting of a NaOH reactor, vertical flow wetlands for excess wet weather flow management, a sludge disposal pond, and constructed wetlands for residual flows located on the opposing side of I-80. A Power Point file print out of the presentation made to the Beech Creek watershed association on January 15, 2007 is included.
