Lead Testing in Drinking Water
The City of Highland Park is continuously paying close attention to what unfolded in Flint, Michigan, and our thoughts are with all those who are struggling without access to safe and reliable water in their homes.  

In light of national events, on July 12, 2016 the City of Highland Park issued an announcement that the City is partnering  with North Shore School District 112, Township High School District 113, the Park District of Highland Park, and the Highland Park Library to take additional precautionary measures to ensure the safety of the delivery of our water by testing all water fountains and drinking water faucets for lead.  

City staff began sample collection in early July of 2016 and finished sampling at the end of September 2016.  All samples were submitted to a certified laboratory and tested for lead.  For more information on the lead testing initiative, see our lead testing FAQ.

As sample results came in, this web page below was updated.  Please review the following result.

 As of September 26, 2016:
  • 665 samples have been collected
  • 665 lead results received
  • Approximately 4 samples to be collected

The United States Environmental Protection Agency’s (USEPA) action level for lead is 15 parts per billion at which point remedial action is recommended. For those fixtures with unsatisfactory lead levels, City staff turned off and covered the affected water fixtures as soon as confirmation was received of lead presence in those fixtures. The City took immediate steps to secure the sites and is in the process of replacing the impacted plumbing and fixtures. The lead testing results are isolated to specific fixtures that were tested and are not reflective of the City’s water production or distribution system. The replaced water fixtures will be retested and won’t be turned back on until fully remediated.

For more detailed information, please see the link understanding the issues of lead in drinking water.

If you are concerned about lead exposure, you can have the water in your home tested for lead. The City of Highland Park Water Treatment Plant laboratory is not certified for metals analysis.  Please see the link of accredited labs for lead testing for a list of laboratories that can test residential water samples.
