Pete Wallers of the Northwest Water Planning Alliance (NWPA) told Kendall County Board members at their Committee of the Whole meeting on Thursday that now is the time to address water needs for 2050.

Wallers said that declining water levels in the deep sandstone aguifers, rising chloride levels in the shallow aquifers and aging municipal infrastructures are the major issues and challenges for the NWPA.

According to Wallers, the problem with the declining water levels in the deep sandstone began in DuPage County.

Wallers said that the City of Joliet is now making plans to get its water from Lake Michigan by 2030, either from Chicago or from Indiana.

Part of Joliet reaches into Kendall County.

And Wallers added that the recharging of the deep sandstone aquifer moves from west to east.

Wallers said that road salt containing chloride is increasing four milligrams, per liter, per year in shallow ground water in Kane and McHenry counties.

And Wallers said the NWPA is trying to limit salt spreading on large commercial and hospital parking lots.

County board Chairman Scott Gryder asked Wallers about the Sandwich Fault Zone.

The Sandwich Fault Zone runs from Oswego to Ogle County.  Wallers said that the sandstone aquifer on the west side of the Sandwich Fault has more water than the aquifer to the east.

DeKalb Kane, Kendall, Lake and McHenry counties are members of the Northwest Water Planning Alliance.
