Prairie Pointe Updates

Mid-April Update

Lake 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 and recently moved to a different well to draw water that contains lower levels of iron.

The Prairie Pointe water system has two water wells. One of the wells had been down for planned maintenance since early February and was returned to service on April 11. Drawing from this source will help reduce the level of iron in the system. 

Meanwhile, repairs to the primary iron filtration system are underway. The contractor is currently 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.

Shown are the two tanks and related control systems in the Lake County Public Works Iron Filter System for the Prairie Pointe water system. A recently awarded contract for $210,194.00 will replace the layers of specialized sand, gravel and interior piping of the tanks as well as modernize the electrical control systems. Work is scheduled to be completed in June 2018.

Filter Tanks

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 discoloration is affecting some customers, and not the entire subdivision due to varying levels of iron in the distribution system.  If you experience yellow water, please run your faucet for 10 to 20 minutes until the water runs clear.  If the water does not clear after a few hours, or if there is also a significant loss of pressure, call the Public Works Department (847-377-7500).

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 up on appliances over the long-term. Customers can consider commercially available soft water solutions to reduce mineral deposits on their appliances. 

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.
