Groundwater Level Monitoring in McLean Tazewell and Logan Counties:
Development of a SubNetwork with Automated Data Collection and Retrieval in Logan County

Principal Investigators: Kevin Rennels, Steve Wilson

Project Period: 05/16/2014 - 05/15/2017
Sponsor: Northern Logan County Water Authority

This project is being conducted to enhance the groundwater level network currently being monitored by the Illinois State Water Survey through a contract with the Long Range Water Plan Steering Committee. The focus of the network is to maintain a record of groundwater level fluctuations in the aquifers south and west of Bloomington-Normal. This project is to add automated recorders and telemetry at 2 wells for continuous water level monitoring. Both wells are currently part of the LRWPSC network and are in Logan County. Their Project ID's are SWS-E and SWS-10. This enhancement of the monitoring conducted from 1999 to date, is for a three years duration from May 16, 2014 to May 15, 2017. The project includes purchase, assembly, installation, and calibration of transducers and cell phone telemetry in 2 wells, regular downloads of those data, yearly reporting of the data, and display of the continuous data on a public website hosted by the ISWS. The wells will also be hand measured quarterly and the sites will be mowed twice a year as part of the existing contract with the LRWPSC.
