  • Orchard Limestone Drain
    Passive Treatment System
    Swatara Creek
    Pine Grove

    Constructed to treat the orchard discharge along Interstate 81. It was rehabilitated in the mid 2000's by USGS and Schuylkill Conservation District after the mountain side blew out and clogged up the treatment system. The mountain side blew out again in 2011 floods covering the treatment system under sediment.
