Program Responsibilities
Geological Services determines groundwater flow parameters including contaminant travel times and directions; effectiveness of monitoring well networks (including compliance with IDNR well installation rules), and evaluates the interactions of contaminated soils with groundwater to determine soil and ground water remediation system effectiveness. Geological Services staff explore sites for features which impact contaminant migration e.g. karst, sediments, bedrock, and topography. The section staff develops and interprets technical guidance and assists enforcement when needed.
