Schuylkill Watershed Abandoned Mine Drainage

Laura Sherrod - 2011

Resistivity surveys in 2009 covered approximately 1800m of stream channel west of Heckscherville, PA.  From these surveys, three target areas were identified for remediation (channel reconstruction or chemical grouting).  Geophysical surveying was continued in 2011 to complete an additional 2300m of resistivity profiles.  Additional remediation may be necessary at some of locations along this length of the stream channel.

Most sections of the stream channel display high resistivity values in the subsurface, indicating a low risk for seepage (above).  However, some sections of the stream show low resistivity values at depth which may correspond to a seepage zone connecting to the underground mine pools (left).
