About this area's water

Did you know
  • The village is named for John McGuffey, who traded land for a railroad depot in exchange for having the town named after him in 1890.
  • Its own three wells produce the lowest disinfection-byproduct levels of the three small systems examined in this batch.
  • A post office at the site predates the village's own 1890 founding by seven years.
  • The 2024 lead service-line inventory found zero confirmed lead pipes among 274 service lines, with just 8 of unknown material.
  • In April 2026 the village council convened specifically to discuss repairs needed on the aging municipal water tower.

Treatment & pressure

How it is treated

McGuffey draws on three groundwater wells and disinfects with chlorine; the resulting disinfection byproducts (TTHM 10.7 ppb, HAA5 0.717 ppb, both well under the 80/60 ppb limits, per EWG's EPA-sourced data) are consistent with simple chlorination rather than membrane filtration or other advanced…

Supply stress

Own three-well groundwater supply is generally more drought-resilient than a surface source, and disinfection-byproduct levels are the lowest of the three systems in this batch, consistent with less chlorination demand and less organic precursor material. Fluoride at 2.09 ppm exceeds EPA's non-enforceable secondary (cosmetic) guideline…

Sewers

Sanitary

Confirmed village-operated: an October 2023 special council meeting adopted ordinances waiving fees/penalties on unpaid 'water and sewer' bills tied to vacant properties (wktn.com), confirming the Village of McGuffey runs its own sanitary sewer utility alongside its water system. No treatment-plant name, capacity, or receiving stream was…

What the records show about Mcguffey Village

Who runs it

EPA's record describes Mcguffey Village as owned by a local government. It has 215 service connections and serves 710 people.

EPA classes it as a community water system, one that serves the same residents all year.

EPA's record says it has substantially implemented source water protection under Ohio's program, dating the program from 2025. Its office telephone on EPA's record is 419-757-2292.

How the water is treated

EPA's treatment table registers these steps for Mcguffey Village: aeration, chlorine disinfection, and sand or media filtration.

The list is what each system registered with EPA for treatment plants EPA still shows as active, and it can lag a plant upgrade.

Violations

EPA counts 1 health-based violation for Mcguffey Village since 2015. Health-based means a contaminant above its legal limit or a required treatment step not carried out. It falls into 1 separate problem (one contaminant or rule in one year); the table lists it.

EPA logs 6 violations of any kind since 2020: 1 for required testing that was missed or reported late; 4 for a report, record or notice that was missing, late or incomplete (the yearly water quality report, a public notice, lead line records); 1 health-based.

Lead and copper at the tap

In the sampling period ending December 2025, the 90th-percentile lead result at Mcguffey Village was 0 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027. A result of 0 means at least nine in ten of the homes sampled had no lead detected.

The highest result on file is 1.2 ppb, in the period ending December 2023.

EPA has 9 sampling periods on file for Mcguffey Village since 2016, the first ending in 2017; no period was above 10 ppb.

Every water system has to inventory its service lines, the pipes from the main to each building. In the inventory Mcguffey Village sent EPA, 274 lines are counted.

Service lines in the inventory
MaterialLines
Lead0
Galvanized, needing replacement0
Unknown material8
Not lead266
All lines274

Systems sample taps in the homes most likely to have lead pipes or solder. The 90th-percentile result is the level nine in ten of the sampled homes were at or below. Lead comes mostly from service lines and house plumbing, not the source water, so a low result for the system does not clear an old house.

EPA's dashboard status for this inventory: reported all required service line types.

PFAS

Ohio EPA's own statewide sampling tested 1 plant of Mcguffey Village (latest sample September 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.

Ohio EPA's current sampling status map lists 1 plant of Mcguffey Village as sampled, most recently July 2026.

PFAS are the 'forever chemicals' from firefighting foam, plating shops and non-stick coatings. Results are for water leaving the plant, not your tap.

Disinfection byproducts

Chlorine that disinfects water also reacts with organic matter to form byproducts. Two groups have federal limits: total trihalomethanes (TTHM, 80 µg/L) and five haloacetic acids (HAA5, 60 µg/L), judged on running yearly averages at each sampling site.

For TTHM, the average of Mcguffey Village's samples in 2019, the last year it was sampled, was 8.3 µg/L. The worst yearly average was 31.7 µg/L and the highest single sample was 37.8 µg/L, from 14 samples taken from 2012 to 2019.

For HAA5, the average in the last year sampled was 0 µg/L. The worst yearly average was 4.9 µg/L and the highest single sample was 9.8 µg/L, from 14 samples.

A yearly average of 0 means nothing was detected in that year's samples. EPA's file stops at 2019; Ohio EPA's Drinking Water Watch has newer results.

Nitrate, arsenic and radioactivity

Nitrate: the highest of 9 samples was 0.28 mg/L (as nitrogen) in 2014; in 2019, the last year sampled, the highest was 0.16 mg/L. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.

Arsenic was not detected in 3 samples (limit 10 µg/L).

Solvents and fuels

EPA's file holds results for all six solvent and fuel compounds it checked. Benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, and vinyl chloride were not detected in 3 samples each.

Farm chemicals and metals

EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: barium in 3 of 3 samples, highest 18 µg/L (limit 2,000). Not detected: atrazine, alachlor, chromium, cadmium, mercury, selenium, and thallium, in 3 samples each.

Bacteria in the pipes

From 2012 to 2019, 0 of 127 routine total coliform samples taken in the distribution system at Mcguffey Village tested positive (0%); in 2019, the last year on file, 0 of 12 did.

A positive coliform test is a warning sign, not a violation by itself. E. coli is a sign that human or animal waste may have reached the water. Coliform counts are routine samples only; E. coli counts include repeat samples.

Fluoride

The Ohio Department of Health's report to the CDC (My Water's Fluoride) says Mcguffey Village has fluoride from natural sources at a level higher than what is needed to prevent tooth decay. The level it reports is 2.09 mg/L.

EPA's treatment table lists no fluoridation step at Mcguffey Village.

Measured fluoride: 2.25 mg/L on average at the plant's entry points in 2018 (high enough that children under 9 can get mottled teeth); samples ran from 2.04 to 2.25 mg/L across 3 samples in 2012 to 2019.

The recommended level for preventing tooth decay is 0.7 mg/L; the federal limit is 4 mg/L. The treatment list is what each system registered with EPA and can lag a plant upgrade.

How well the service area is mapped

EPA estimated the service area of Mcguffey Village with a computer model rather than drawing it from the utility's map, so its edges are approximate.
