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…

Water pressure
Not published in any source located — no CCR, engineering report, or council record with pressure-zone or tank-elevation data was found.
What it costs
No metered rate schedule was found in a published ordinance. A March 2026 village Facebook video referenced usage-based billing (roughly $3.50 per unit of gallons above a base…

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…
