Columbia Falls well closed after ‘forever chemicals’ found
The city of Columbia Falls has removed one of its three water wells from service after perfluorooctanic acid (PFAS) was detected above Environmental Protection Agency standards. The LP well sampled at 7.2 parts per trillion, exceeding the EPA maximum contaminant level of 4 parts per trillion, prompting its closure as a precaution on September 21, 2026. The city's two other wells are unaffected and can meet current demands, so no 'do not drink' order has been issued.
