Within McHenry County, IL, the fastest growing county in Illinois, groundwater is used for 100% of
the water needs. Concerns over water resources have prompted the investigation of the surficial
sand and gravel aquifers of the county. While the eastern portion of the county is urbanizing, the
western portion remains devoted to agriculture. High-capacity irrigation wells screened within
the surficial sand and gravel aquifer are used for crop production. To assess the impacts of the ir-
rigation wells on the aquifer, a groundwater flow model was developed to examine five different
scenarios reflecting drought conditions and increased pumping. Results show that the surficial
sand and gravel aquifer is capable of meeting current water demands even if recharge is de-
creased 20% and pumping is increased 20%. The additional loss of discharge and increases in
pumping result in head differences throughout the aquifer.
