Monroe's tap water comes from Lake Erie — and what that means in summer
Monroe draws drinking water from western Lake Erie, where summer algae blooms are watched closely and treated by the city water department.
Monroe gets its drinking water straight from Lake Erie — the lake’s shallow western basin, which the city’s water plant has drawn from for about a century. That’s worth knowing, because western Lake Erie is prone to summer “algae blooms.” When warm weather and farm-fertilizer runoff combine, the water can grow big mats of blue-green algae. Some of it produces a toxin. You may remember that a bad bloom briefly shut down nearby Toledo’s tap water back in 2014.
The good news for Monroe: the city’s water department watches for this closely and treats the water to remove the toxins. Monroe’s tap water has stayed safe through these blooms. So this isn’t a reason to avoid the area. But if you’re moving here, it’s good to know where your water comes from. Pay attention to the city’s water notices in late summer. And know that some residents keep a filter or bottled water on hand in heavy bloom years, just for peace of mind.
