Aqua Water Information

A message from Aqua Water 7/20/19

Good afternoon, this is Melissa from Aqua Illinois. We want you to know that customer safety is our top priority.

As we continue working to resolve this situation, it is important to us that you have the most accurate information. Here are a few things we want you to know about how you can use your water, how to reduce lead exposure, water deliveries, and new information center hours:

  • According to the Centers for Disease Control and Prevention and the U.S. Environmental Protection Agency, human skin does not absorb lead in water. Per the CDC and EPA, tap water may be used for other daily uses, including bathing, hand washing, washing clothes, and washing dishes. For these non-consumption uses, you do not need to use bottled or filtered water.
  • You can drink, cook, brush your teeth, and make formula and ice cubes with your tap water when it is filtered according to the manufacturers’ instructions through faucet filters or pitcher filters certified by the National Sanitation Foundation to reduce lead like those Aqua Illinois provided and made available to customers.
  • Our sampling results show that after running the faucet for two to three minutes, 95 to 97 percent of samples are below the EPA action level. Our finding is consistent with guidance from the EPA stating that flushing your pipes reduces lead in your drinking water.
  • Samples taken after running the faucet for two to three minutes represent more typical exposure during a normal day because people are regularly using their water. This “flushing” ensures you are getting fresh water from the main.
  • We recommend you flush your pipes for two to three minutes before use to reduce your lead exposure.

 Aqua Illinois continues to ensure our customers have access to important resources. Please note, if you remain affected, you will receive a water delivery on Sunday, July 21. Starting on Monday, July 22, Aqua will be making bottled water deliveries on Mondays, Wednesdays, and Fridays. 
Also effective on Monday, July 22, the Aqua Information Center located at 90 Towncenter Drive in University Park will operate on Tuesdays, Thursdays, and Sundays from 11 a.m. to 5 p.m. At the Information Center, you can pick up bottled water, faucet filters or pitcher filters, apply for water sampling and recycle your water bottles. A member of our team is also on hand to fill your personal containers with water from a water truck on site.
You can visit or call 877.987.2782 at any time to request these resources.
Please visit for the current Information Center hours and for the most recent information.
We appreciate your patience as we work with regulators and local officials day in and day out to restore drinking water for all our customers as soon as possible.

Thank you.

Post Flush Data - July 16, 2019

Aqua Illinois has been proactively investigating and resolving the lead situation in University Park. In addition to the IEPA-required compliance sampling that shows lead results for water that has been stagnant in pipes for more than six hours, another data set we are examining measures lead in water after two to three minutes of flushing. We call these data “post-flushing data.” These data demonstrate how running your water for two to three minutes reduces lead levels. This flushing allows homes and businesses to draw fresh water from the system. Data from samples taken after running the faucet for two to three minutes represent more typical exposure during the course of a normal day.  

Post Flush Data- July 16, 2019 presentation

Explaining compliance samples
The U.S. Environmental Protection Agency, through its lead and copper rule, requires water utilities to work with their customers to collect regularly scheduled stagnation samples or compliance samples.  This rule is designed to gather samples of water that have remained in customers’ pipes for six or more hours. Water that sits in pipes unused for six or more hours provides worst-case scenario data for lead exposure. The U.S. EPA deems water treatment effective when test results are less than15 micrograms per liter (ug/L) across 90 percent of sample locations. Utilities must choose locations to sample representations of the highest inventory of lead– for example, Tier 1 locations include those with lead service lines or lead solder on copper pipes on homes constructed after 1982. The lead and copper rule does not set a health-based lead limit. It is a treatment-based rule. That means if 90 percent of compliance samples are less than 15 ug/L, treatment is deemed effective, and any samples over 15 ug/L are analyzed on an individual basis. Do not consume advisories can be issued to be proactively protective.
To complete compliance sampling, Aqua Illinois provides bottles and instructions to participating customers, who then collect the samples. We pick up the compliance samples when customers tell us the samples are ready, and then we send them to an independent lab for testing.

Lead Analytical Results
Recent University Park sampling was done under Aqua Illinois 's Kankakee's facility ID after the switch over.  Data for lead analytical results for University Park’s water can be accessed as follows:
  • For lead data before 2018, use Aqua Illinois-University Park (IL1975030)
  • For lead data between 7/1/2018 and 6/30/2019, use Aqua Illinois-Kankakee (IL0915030)
  • For lead data after 7/1/2019, Illinois EPA will be switching back to Aqua Illinois-University Park (IL1975030)
