Research finds threats to McHenry County water

CHAMPAIGN (AP) — The Illinois State Water Survey says research shows groundwater resources in McHenry County could become strained in the next three to four decades.

The water survey cites a study by hydrogeologist Scott Meyer. He mapped water levels for more than 300 wells in McHenry in 1994 and 2011. Researchers also used computer models to simulate groundwater flow. Results suggest there may be enough drawdown from deep wells that production could be affected by 2030.

Researchers say if well pumps are deep enough the water drawdown could cause wells to fail to provide expected water amounts.

Meyer says research also found there could be significant drawdown near shallow well fields that supply public water systems.

The study found an 11.5 percent reduction in natural groundwater discharge in McHenry County.
