Lake Forest, IL – A citywide boil order was issued Friday afternoon after a significant water main break on Westleigh Road caused water pressure in Lake Forest to drop below safe levels.
According to the City of Lake Forest and the Lake County Health Department, the alert went into effect at 4:09 p.m. on October 10, 2025, following the discovery of the break that impacted the city’s water system.
Officials said the water remains safe for most household uses, including laundry and cleaning, but should not be consumed unless boiled first. Residents and businesses are urged to bring all water to a rolling boil for at least three minutes before using it for drinking, cooking, brushing teeth, or washing food.
Bottled water may also be used as an alternative until further notice. The advisory will remain active until laboratory testing confirms that the water meets Illinois Environmental Protection Agency (IEPA) standards.
City officials said updates will be provided as soon as test results become available. Crews are currently working to repair the affected main and restore normal water pressure throughout the city.
Residents are thanked for their patience as teams work to resolve the issue quickly and safely.
