About this area's water

Did you know
- The entire supply for 26,822 people served directly - 42,742 including satellite systems - comes from a single radial collector ('Ranney') well: one shaft with horizontal arms reaching out into the Ohio River's buried…
- The well that supplies 'Belmont County' water isn't in the district's St. Clairsville home base at all - the wellfield sits inside the Village of Bellaire, and Ohio EPA found the district's protection area overlaps…
- In the 1990s Ohio EPA traced industrial solvent contamination in the wellfield to a source just south of the Ranney well, and ODOT later excavated the contaminated soil.
- Water and sewer rates rise 2.5% automatically every year under the adopted rate schedule, rather than going back to the county commissioners for a fresh vote each time.
- The district replaced a water plant built in the 1960s with a new 6 MGD plant costing roughly $27.7 million - and its 10-year plan already contemplates pushing that to 9 MGD with a new 3 MGD vertical well.

History6
- 1990sOhio EPA sampling finds VOCs in the district's water on 13 occasions: cis-1,2-dichloroethylene 11 times at 2.0-6.9 ug/L, 1,1,1-trichloroethane once at 0.6 ug/L, and cis-1,2-dichloroethene once at 1.3…
- 1997Ohio EPA leads a ground water investigation of the well field that identifies a source of VOC contamination south of the Ranney well, inside the one-year time of travel. Lawhan & Associates prepares…
- after 1997ODOT initiates a cleanup project that removes the contaminated soil. Ohio EPA's bibliography also cites IT Corporation's 1999 'Final PCE Source Identification and Contaminant Delineation Technical…
- 2000-2024No detections of 1,1,1-trichloroethane; 7 detections of cis-1,2-dichloroethylene, all below 2 ug/L - a clear decline from the 1990s.
- 2019Manganese detected once at 0.206 mg/L, above the 0.05 mg/L concentration of concern (an aesthetic secondary standard, not a health-based MCL).
- 2023A new 6 MGD water treatment plant, built with USDA financing on Guernsey Street in Bellaire and replacing a plant dating to the 1960s, is reported complete.

Treatment & pressure
How it is treated
One radial collector ('Ranney') well north of Bellaire draws from a sand-and-gravel water-rich zone in the Ohio River Buried Valley aquifer system. Ohio EPA's 2024 assessment modeled it at 4,349,000 gallons/day (the average daily rate in Ohio EPA files plus 15%); the district's own 2025 plan says…

Water pressure
Not published. Neither the 2025 Drinking Water Source Protection Plan nor the 2025 CCR gives system pressures, pressure zones or tank elevations.
What it costs
$7.69 per 1,000 gallons
Typical household bill about $58 a month for water.
Effective January 1, 2025: residential water minimum bill $26.92 with NO gallon allowance, plus $7.69 per 1,000 gallons; bulk users pay a flat $10.00 per 1,000 gallons. The $57.68…

Supply stress
Ohio EPA rates the source HIGH susceptibility to contamination, for five stated reasons: a relatively permeable layer of silty clay and fill overlying the aquifer; shallow aquifer depth (less than 20 feet below ground surface); past identification of VOC-contaminated soils within the one-year time of travel; significant potential…
