The Michigan Department of Environment, Great Lakes and Energy announced Monday that drinking water in Benton Harbor met standards for lead levels in the latest round of monitoring, marking the third straight six months that lead readings have been below the federal action level.
Benton Harbor was placed under a state advisory in 2018 after high levels of lead were found in the city’s drinking water, prompting six-monthly reviews instead of annual sampling. Lead is a potent neurotoxin that can cause brain damage and developmental delays. About 10 thousand people use the drinking water network of the city.
EGLE tested water at 65 locations, including 39 residential locations, between July 1 and December 31 last year. Ninety percent of the test results showed the water had a lead level of nine parts per billion or less. No level of lead is considered safe, especially for children.
Two residential sites had lead levels above 15 parts per billion, the federal action level for lead safety. EGLE said the main service lines at these sites were replaced after the samples were taken.
The latest sampling round showed lead levels that were lower than the previous two sampling rounds, marking the third time in a row in 18 months that Benton Harbor’s drinking water has met the safety standard.
“This is positive news and evidence that Benton Harbor’s critical infrastructure work has reduced the risk of lead service lines,” Eric Oswald, director of EGLE’s Division of Drinking Water and Environmental Health, said in a statement Monday. “That being said, today’s news does not diminish the need for continued education about the proper use of filters, the removal of lead plumbing from homes, and the continued improvement of the drinking water system.”
The southwestern Michigan city, which is majority black, has had three consecutive years of drinking water levels exceeding state and federal action standards of 15 ppb in early 2021. The Detroit News reported in 2021 that environmental protection officials and the city were lax. to combat the urine contamination crisis by failing to warn residents about the dangers of drinking water and measures to combat its corrosion.
In late September 2021, the state began providing free bottled water and tap water filters after a group of concerned residents, safe water advocates and environmentalists requested emergency federal intervention to restore clean drinking water in Ask for the harbor.
In addition to treating the water with a corrosive chemical mixture, state officials have accelerated efforts to replace Benton Harbor’s service lines. 99.5 percent of the initiative has been implemented, said a state panel. Governor Gretchen Whitmer announced executive order in 2021, government departments will be ordered to “immediately” replace lead service lines.
The Michigan Department of Health is still recommending that residents use filtered or bottled water for drinking, cooking, brushing teeth, washing food and mixing baby formula until the department confirms their home plumbing is lead-free.

State drinking water experts are working with Benton Harbor Water Treatment Plant employees to improve the plant’s corrosion control processes, which will reduce the amount of lead that dissolves into the water as it passes through lead fixtures.
