Project Understanding

Blackstone provides routine groundwater monitoring and compliance services for the City of St. Joseph Sanitary Landfill and the closed McArthur Drive Landfill.

Services Provided

  • Blackstone provides routine semi-annual groundwater monitoring and statistical evaluation for the St. Joseph Sanitary Landfill and annual monitoring of groundwater, sediment, and surface water for the closed McArthur Drive Landfill.
  • Non-routine groundwater services have included investigation of VOC detections in groundwater; preparation of sampling and analysis plans; background statistical updates; hydrogeological site characterization activities; investigation of fluctuating water levels in multiple monitoring wells using downhole camera inspection; and installation of replacement monitoring wells.
  • Blackstone completed oversight and installation of a complex site-wide nested perimeter gas probe monitoring system as part of ongoing lateral expansion activities. Installation activities also required preparing a minor permit modification for MDNR approval.
  • Blackstone completed biennial airspace estimates, including aerial survey, airspace calculations, and landfill life estimates.
  • Blackstone prepared a comprehensive Erosion Control Plan to address effluent limitation exceedances, including lined stormwater letdowns, stormwater terraces, and increased vegetation on the landfill slopes.
