Cleveland OH metro: water quality. Cleveland and Akron anchor a metro of 2.1 million people in northeast Ohio.
Cleveland and Akron anchor a metro of 2.1 million people in northeast Ohio. Cleveland Water draws from Lake Erie through four intake cribs positioned miles offshore, serving about 1.5 million people across the city and 70+ suburban communities. Akron operates a separate system from Lake Rockwell, C.V. Shank Reservoir, and the Ohio Canal. The two systems face different challenges: Cleveland contends with Great Lakes water quality and aging infrastructure, while Akron manages a reservoir-based supply in a region marked by rubber and polymer manufacturing history.
Lake Erie – shallow, warm, and surrounded by agricultural runoff and urban discharge – is the most biologically productive of the Great Lakes. That productivity comes with water quality trade-offs.
Lake Erie receives inputs from the Cuyahoga River (historically one of the most polluted rivers in America – it famously caught fire in 1969), the Rocky River, and numerous smaller tributaries draining industrial and residential areas. UCMR5 monitoring for Cleveland Water has shown detectable PFAS in treated drinking water, though at levels below the federal MCLs.
Akron's reservoir supply has shown lower PFAS concentrations in testing to date. The city's distance from the Lake Erie shoreline and direct military installations shields it from some of the point-source contamination that affects lakefront communities.
Ohio EPA has been monitoring PFAS across the state and identified industrial facilities in northeast Ohio – including polymer manufacturers and chrome plating operations – as potential PFAS sources. According to a 2024 Ohio EPA screening report, four community water systems in the Cleveland-Akron area reported PFAS detections above the agency's updated screening levels.
Cleveland's Lake Erie supply ranks in the middle among Ohio metros. Columbus's protected reservoirs test cleaner, while Cincinnati's Ohio River intake faces heavier upstream industrial contamination. Within the Great Lakes region, Cleveland faces similar challenges to Detroit (Lake Erie/Huron supply), though Michigan's stricter state standards mean Detroit-area water gets more scrutiny.
The Cuyahoga River cleanup – a multi-decade effort that has transformed the river from an environmental cautionary tale to an Area of Concern showing measurable recovery – demonstrates that improvement is possible, but legacy contamination in sediment and groundwater persists.

Cleveland and Akron residents face different contaminant profiles based on their water source. Lake Erie-sourced water carries more industrial and agricultural contaminant potential; Akron's reservoir water is more insulated.
