The City installed a gas collection system in 1985, a methane gas monitoring program in 1999 and an environmental monitoring program in 2003. This program currently includes:

  • Gas monitoring at the north, west, and south boundaries of the site
  • Seven surface water monitoring stations in German Mills Creek
  • Groundwater monitoring
    • 10 locations with 10 wells
    • 2 piezometers next to the creek
