In a recent government meeting, officials discussed critical updates regarding water supply and quality in Joliet, addressing concerns about the reliance on groundwater and the presence of PFAS contaminants. The meeting highlighted plans to establish a new water source aimed at reducing dependence on the aquifer, which has been experiencing low water levels. Officials confirmed that while the new pipeline will serve as the primary water source, existing wells will remain operational as a backup.

The conversation also touched on the ongoing challenges posed by PFAS, a group of harmful chemicals found in water supplies. Officials noted that while the City of Chicago, which supplies water to Joliet, has not detected PFAS at levels requiring regulation, the city does not currently employ treatment technologies specifically for PFAS removal. This raises concerns, especially since Lake Michigan, the water source, also contains PFAS.

Further discussions revealed that previous analyses of alternative water sources, including the Des Plaines River, indicated that aquifer recharge was not feasible due to the area's unique geology. The river, primarily composed of wastewater from Chicago, was deemed unsuitable for sourcing clean water, as per regulations from the Illinois Environmental Protection Agency (IEPA).

The meeting also addressed the distribution of water quality reports to residents. Joliet officials confirmed that annual water quality reports are available online and can be requested in hard copy, although they are not automatically mailed to residents.

As the meeting progressed, officials emphasized the importance of the new 60-inch pipeline infrastructure, which is critical for ensuring a reliable water supply. They assured that extensive precautions are being taken in the design and installation of the pipeline to prevent potential failures that could disrupt service or pose risks to public safety.

Overall, the discussions underscored the city's commitment to improving water quality and supply while navigating the complexities of environmental regulations and public health concerns.
