Quick Answer
Is lead in drinking water a real concern in Ohio?
Yes — Ohio's older industrial cities have significant lead service line inventories and aging household plumbing.
Is this mostly a public-water issue, a private-well issue, or both?
Primarily public water service lines and older household plumbing; Cleveland, Toledo, Akron, and Columbus have documented aging infrastructure.
What is the main reason residents should care?
Ohio's older industrial cities were built when lead was a standard plumbing material. Ohio EPA enforces the Lead and Copper Rule and requires utilities to complete lead service line inventories under federal LCRR requirements.
Key Facts
| Federal Lead Action Level | 15 µg/L — zero is the CDC-recognized safe threshold |
| Federal MCLG | Zero |
| Older housing risk | Homes built before 1986 most likely to contain lead solder or fittings |
| Regulatory framework | Ohio EPA enforces Lead and Copper Rule Revisions |
| State oversight | Ohio Environmental Protection Agency (Ohio EPA) |
Why This Matters in Ohio
Ohio's legacy industrial cities — Cleveland, Toledo, Akron, Youngstown, and Canton — have drinking water infrastructure built over the past century, much of it using materials that are now understood to be a lead risk. Cleveland has been working on systematic lead service line replacement for more than a decade. Ohio EPA enforces the Lead and Copper Rule and adopted the revised requirements. Like neighboring Michigan, Ohio saw increased attention to lead in water following the Flint crisis, prompting more aggressive monitoring and replacement programs.

How Lead Gets Into Drinking Water
Lead service lines
The pipe connecting a home to the water main may be made of lead, especially in pre-1986 construction. Water sitting in these lines can accumulate lead before it reaches the tap.
Lead solder
Lead solder at pipe joints was banned for potable water systems in 1986. Homes built before that date — including significant portions of older Ohio cities — may still have lead solder throughout their plumbing.
Older brass fixtures
Faucets, valves, and fixtures with high lead content were common before the 2014 revision of 'lead-free' standards. Replacing older fixtures at kitchen and drinking taps can meaningfully reduce exposure.
Corrosive water chemistry
Soft, acidic, or low-alkalinity water dissolves lead from plumbing more readily. Utilities use orthophosphate and other corrosion control treatments, but household plumbing after the meter is not within their control.
Who Should Pay Closest Attention
Residents in older neighborhoods of Cleveland, Toledo, and Akron are at greatest risk, particularly those in pre-1978 housing. Families with children under six and pregnant residents should consider testing and a certified NSF/ANSI 53 or 58 filter.
Families with children under six
Pregnant residents
Households in homes built before 1986
Renters who cannot inspect building plumbing
Residents on a confirmed lead service line
Households that had plumbing work done recently (disturbances dislodge protective scale)
How to Check Your Situation in Ohio
- 1
Identify your water utility. Use the ZIP lookup below or browse the Ohio utility directory on this site.
- 2
Read your utility's page on this site to see its current risk level and any open lead violations.
- 3
Contact your utility and ask for your address-level service line material status. Under the federal Lead and Copper Rule Revisions (LCRR), utilities must maintain and provide this information.
- 4
Review your utility's most recent Consumer Confidence Report (CCR) — mailed annually or available on the utility's website.
- 5
Consider testing your tap water at a Ohio Environmental Protection Agency (Ohio EPA)-certified lab. Your state health department or Ohio Environmental Protection Agency (Ohio EPA) maintains a list of certified labs.
- 6
If you have young children or are pregnant, install a certified NSF/ANSI 53 or 58 filter at the kitchen tap as a precautionary measure.
Treatment Options
Boiling does not remove lead. Use a certified filter for drinking and cooking water.
NSF/ANSI Standard 53 — Activated Carbon Block
Under-sink or pitcher filters certified to Standard 53 are independently verified to reduce lead. Replace filters on the manufacturer's schedule — an overdue filter may not perform as certified.
NSF/ANSI Standard 58 — Reverse Osmosis
RO systems certified to Standard 58 remove 95–99% of lead and a broad range of contaminants. Requires under-sink installation. More comprehensive than Standard 53 for households with multiple contaminant concerns.
Flushing — temporary mitigation only
EPA recommends flushing the cold tap for 30 seconds to 2 minutes if water has sat in pipes for 6+ hours. Not a substitute for certified filtration or service line replacement.
