Senior Scientific Specialist, Hydrogeology

Work alongside and provide hydrogeologic consulting services to Illinois Department of Transportation (IDOT) personnel. Project specific focus will be the long-term maintenance and operation of dewatering efforts (i.e., removing excess groundwater to protect vital infrastructure). This project/position has been active since the 1980s and is projected to continue for the foreseeable future.

Duties & Responsibilities

• Field work weekly from April – November annually.
• Summer field season includes well rehabilitations (i.e., acidification and sonar pulsing) to remove iron and bacterial buildup on well screens.
• Oversee rehabilitation teams and report progress to IDOT staff.
• Participate in sand tests for Ranney Collector Well to ensure that the system is functioning properly.
• Measure groundwater levels regularly.
• Maintain and ensure long-term functionality of telemetry stations that monitor and record groundwater levels hourly.
• Installations of automated monitoring telemetry stations, as needed.
• Field work may require interaction with property owners or the public but will likely be predominantly interacting with IDOT personnel.
• Hydrogeologic Consulting: Respond to requests from IDOT staff about regional/local hydrogeologic information. Produce monthly reports of local groundwater levels for IDOT staff.
• Other: Perform other duties as needed to further the mission and goals of the Illinois State Water Survey, the Prairie Research Institute, and the University of Illinois.
