About this area's water Ross County Water Co. Inc

Did you know
- The company draws from the Teays River Aquifer, which its CCR calls one of the three major underground aquifers in the state of Ohio - the buried channel of a pre-glacial river.
- A single eight-well field feeds two treatment plants, North and South, each rated at 3.5 million gallons per day.
- It is a nonprofit, member-owned utility run by five trustees and 42 employees, serving about 15,000 customers across Ross, Pike, Pickaway, Vinton, Hocking and Jackson counties.
- Finished water leaves the plants at 120-140 mg/L hardness (7-8 grains per gallon) with unusually high alkalinity of 240-280 mg/L.
History4
- 1980IRS grants Ross County Water Company tax-exempt status as a 501(c)(12) member-owned mutual utility, effective September 1980.
- 2024Company reports no MCL or action-level violations across bacteriological, radioactive, disinfection-byproduct, lead/copper and PFAS monitoring.
- 2024Participates in EPA's fifth Unregulated Contaminant Monitoring Rule round; of 29 PFAS compounds plus lithium, only PFPeA is detected, at the South plant.
- 2024A system-wide water rate increase takes effect with July 2024 billing.
Treatment & pressure
How it is treated
Eight wells in the buried Teays Valley aquifer feed two 3.5 MGD plants (North and South). The CCR does not publish the treatment train; finished water is chlorinated (1.21 ppm) and fluoridated (0.90 ppm), leaving at 120-140 mg/L hardness and 240-280 mg/L alkalinity.
Water pressure
not published - no system-wide psi figure appears in the 2024 CCR or on the company's website; water is delivered from two plants across a rural six-county network.
What it costs
$9.68 per 1,000 gallons
Effective with July 2024 billing, 5/8" meter: $26.54 minimum for the first 1,500 gal, then $9.68/1,000 gal for the next 8,500, $7.82 for the next 40,000, $5.04 above 50,000.…

Supply stress
Ohio EPA's source water susceptibility analysis rates the aquifer at this well field HIGH susceptibility to contamination, because of the aquifer's sensitivity and several potential contaminant sources inside the protection zone - though no contamination has been detected. Growth pressure comes from continued rural expansion needing new…
