Cottage Grove's 12 wells draw from the Jordan aquifer, and its 2025 water quality report lists hardness at 298 ppm, about 17 grains. The city's Low Zone treatment plant, which uses carbon filters for PFAS along with iron and manganese, has been running since June 2025, paid for by the 3M settlement.
