Summary Abstract: Elevated chloride concentrations (>250 mg/l) were reported to the Ohio State Environmental Protection Agency in the early 2000s by a rural resident using groundwater for domestic consumption from a private water well. An adjacent commercial oil and gas pipe yard had spread relatively small volumes of oilfield brines from 1998 through 2000 to control dust during summers and to de-ice on the property driveways; county and state agencies used halite and other brines on surrounding rural county and state highways during the winter. There are multiple sources in the immediate area that might have contributed to local groundwater by varying degrees, resulting in elevated chloride concentrations reported in the samples from the […]
