Annual Lead Testing of City-Owned Buildings

Annual Lead Testing of City-Owned Buildings
The drinking water produced by the City of Highland Park’s Water Production Division is of the highest quality and has been shown to be free of lead.  However, lead may leach into the water after it leaves the Water Plant as it travels through service lines and through a building’s interior plumbing.  Since water testing is the best way to identify elevated lead levels and eliminate problems, Mayor Nancy Rotering voluntarily initiated an annual program in 2016 to test all City-owned buildings for lead in the drinking water.

The City of Highland Park performs the annual lead testing each fall.  City staff collect samples from all drinking water fixtures in City-owned buildings and send the samples to a certified laboratory to be tested.  Any fixtures found to have a lead level above the USEPA’s limit of 15 parts per billion (ppb) will be turned off and covered.  The affected fixtures will be remediated or replaced and will not be put back into service until follow-up tests confirm that the water is acceptable for consumption.

Results from the most recent lead testing in 2023 can be found here.
