Groundwater Levels Data Report
BACOG’s groundwater level assessments include compiled measurements for 61 wells in our region, three transducer-equipped monitoring wells, 14 dedicated monitoring wells, and five stream gages in Flint Creek. BACOG’s groundwater monitoring programs are assisted by the USGS, ISGS, and ISWS. Thank you to the surveys and their staff and our collaborating municipalities and water operators for participating in this data collection effort. A full copy of the report, BACOG 2021 Groundwater Levels Compilation Report, is available here. This data will be used in the next five-year comprehensive water levels and trends report.
Assessment of Area Groundwater Quality
BACOG’s analysis of water quality in the area’s shallow aquifer system, Assessment of the Natural Groundwater Quality in the Shallow Aquifer System of the Barrington Area Council of Governments Region, 2008 -2018, is available here. Nearly all Barrington Area residents draw water from this interconnected source, whether they rely on a municipal water system or have a private or community well. As a result, a deteriorating groundwater supply or declining groundwater quality could threaten public health and safety as well as our local economy. Understanding and protecting this natural resource is of utmost importance to each of the BACOG government members and our entire community.

Illinois State Water Survey (ISWS) Presents 5 Year Groundwater Levels Report
After five years of data collection by the BACOG office, BACOG contracted with the Illinois State Water Survey (ISWS) to analyze changes in our area’s groundwater during the period 2014-19. This effort describes the trend in water levels in the shallow aquifer system, notes connections between groundwater and surface waterways, and shows water use from municipal wells.
Daniel Hadley, principle author of the ISWS report, presented the maps and findings to the Executive Board July 28th , 2020 in an online meeting.
