Treatment & pressure
How it is treated
Seven production wells in a shallow sand-and-gravel aquifer along the Ohio/Muskingum River valley feed a plant that is staffed 24 hours a day, seven days a week and runs more than 600 water samples a month. Treatment is lime softening plus sodium hexametaphosphate for corrosion control, which EPA…

Supply stress
High. Ohio EPA's September 2015 source assessment rates the shallow (<30 ft) sand-and-gravel aquifer HIGH susceptibility to contamination, and the aquifer already hosts a PCE plume that has been actively contained since 1986. Since 2019 it has also faced brine migration from Class II oil and gas injection wells: ODNR confirmed waste from…
