Residents of Highland Park are being urged to boil their water before use after a sudden drop in water pressure raised concerns about possible bacterial contamination in the local water system.
According to the Highland Park Water Department, the drop in pressure was detected on March 4, 2025. While the exact cause is still under investigation, officials believe it may be linked to changes within the Great Lakes Water Authority system. Loss of pressure in a water system can allow bacteria and other contaminants to enter the water supply, prompting this precautionary advisory.
Until further notice, all water used for drinking, cooking, brushing teeth, washing dishes, and preparing food must be boiled. Water should be brought to a rolling boil for at least one minute, then cooled before use. Alternatively, residents may use bottled water.
Boiling is necessary to kill any bacteria or organisms that may be present in the water. Even if you use a filter for reducing lead or other contaminants, you should still boil the water after filtering it. Once the advisory is lifted, water filters should be replaced.
Water department staff, along with the Great Lakes Water Authority, are working to restore normal water pressure and are implementing corrective measures, including flushing the system. In addition, samples will be collected and tested on March 5 and March 6, 2025, to determine whether the water meets state drinking water standards.
The boil water advisory will remain in effect until test results confirm the water is safe to drink. Officials estimate that the issue could be resolved within 72 hours, though residents are encouraged to stay alert for further updates.
Residents with questions or concerns can contact the Highland Park Water Department at 313-865-1876 or via email at hpwaterdepartment@metroca.net.
The community will be notified immediately once the boil water advisory is lifted.
