Treatment & pressure

How it is treated

Groundwater from 10 wells in Gallipolis and Addison Townships, drawing on the Ohio River Valley Aquifer, is treated at an Ohio EPA Class II water treatment plant that runs 24 hours a day, 7 days a week, 365 days a year. The CCR does not itemize the process train, but chlorine and fluoride are both…

Water pressure

Not published. No CCR, engineering report or pressure-zone map giving a psi figure was found.

What it costs

$9.70 per 1,000 gallons

Typical household bill about $46 a month for water.

Declining-block schedule published by the association. On a 5/8-inch meter the minimum bill is $27.00, covering the first 2,000 gallons ($13.50 per 1,000). Above that: $9.70 per…

Supply stress

Ohio EPA rates the aquifer supplying Well Field #1 as HIGH susceptibility to contamination, on the strength of a documented ground water contamination by volatile organic chemicals in the raw water in the early 1990s. Well Field #2 is rated MODERATE, because of the aquifer's sensitivity and several potential contaminant sources inside…
