May 16, 2017 Environmental Breakfast - Illinois' Legacy Landfills and Impacts on Water Quality 

With Special Guest Speaker, Christopher Stohr, PhD

The A&WMA Lake Michigan States Section and the Union League Club Environmental Committee are pleased to invite you to join us to hear Dr. Christopher Stohr speak at the May 16th Environmental Breakfast on Illinois’ Legacy Landfills.

Dr. Christopher Stohr is an engineering geologist specializing in remote sensing, image processing, photogrammetry, LiDAR, 3D mapping, conventional and satellite surveying, natural hazards, and waste management at the Illinois State Geological Survey, a unit of the Prairie Research Institute at the University of Illinois at Urbana-Champaign. Dr. Stohr has served as a consult expert on the Earthline landfill in Wilsonville, Illinois.  He is currently working with colleagues to refine a remote sensing method that will improve monitoring of landfills (dumps) that will help protect water quality.

      Isolation of wastes from potable water resources is a foundation of modern sanitation and public health. There are 3,430 closed dumps and landfill complexes in Illinois of which only a few are actively monitored. Of these, 1,524 lie over shallow aquifers within 20-feet of the land surface. 95% of the landfills are within km of high, medium or low intensity development. In east central Illinois 218 landfills lie over the Mahomet Aquifer of which about one-half lie over shallow aquifers that supply drinking water to individuals across the region.

      The Earthline hazardous-waste landfill in west-central Illinois is notable for setting several legal precedents regarding isolation of chemical wastes (public right to know, trade secrets, tracking of wastes, list of contents in a container). Leakage of contaminants revealed several problems inherent with unlined landfills including infiltration through the earthen covers, leakage through fractures in weathered glacial sediments and sand channels, burial of liquid wastes, and piping of soils.

     Customary “walkover” inspections provide limited information for post closure landfill monitoring, but can be improved with interpretation of publicly available, digital, 4-band, aerial orthophotography, airborne lidar for defects (several examples). Dr. Stohr will talk about the potential threats to water quality associated with landfills across the state and methods for monitoring these sites.
