Prairie Pointe Updates
End of April UpdateLake County Public Works continues to mitigate iron in the water that is causing discoloration (yellow) for some customers in Prairie Pointe. After an unexpected failure in the primary iron filtration system that treats the naturally occurring iron in the well water, the County implemented a back-up filtration system.
The County switched to a different well in mid-April that had been offline due to maintenance when initial field tests showed the alternate well water contained lower levels of iron. Switching wells unfortunately has had only a minor impact. The two wells are at different depths but draw from the same aquifer. New lab results show that after drawing water from the alternate well for a few days, the iron levels are now similar to those found in the original well.
Meanwhile, repairs to the primary iron filtration system continue. The contractor is manufacturing a piping system that goes into the bottom of the filter tanks. On-site installation will begin in mid-May and the repairs will be completed by the end of June. We continue to work with the contractor on an expedited schedule.
Is the water safe?
Yes, the water is safe to consume. Lake County tested for the Illinois EPA Primary Standards for “contaminants considered a risk to human health” on March 14 and April 4 and the results were fully satisfactory. Lake County has also started testing for iron levels, which is part of the Illinois EPA Secondary Standards for contaminates, which may cause aesthetic problems (color, smell and odor) on a weekly basis. The tests show that the drinking water is in compliance with Illinois EPA regulatory standards.

We recognize residents are concerned and may choose to drink bottled water during this time.
What happened? Some customers may be experiencing discolored (yellow) water through some of their faucets. The water is safe to drink and is in full compliance with EPA standards. Customers may find it occurs in faucets that aren’t run as much as others.
The yellow water is due to higher concentrations of iron in the water due to an unexpected failure of the system that treats the naturally occurring iron found in the well water.
What should I do?
The yellow water from this issue will not have an immediate impact on appliances. Generally, hard water (from wells) has a higher mineral content and can build
Will I get a credit for my increased water usage?
Lake County is offering a credit of up to 2,000 gallons for customers who have a significant increase in water usage due to flushing their lines. Customers should contact the Public Works Department at 847-377-7500 for more information.
Why did this happen?
The iron removal treatment system for the Brooks Farm water system was on our schedule to be replaced next year, but it unexpectedly failed sooner.
