Here is what the EPA's own data shows about tap water in Blackfoot. According to EPA SDWIS data retrieved October 2026, Blackfoot is served by 13 active community water systems, together reported to serve about 14,504 people.
As of October 2026, EPA records show 215 violations across the community water system(s) serving Blackfoot, going back to the earliest EPA record. 9 of these are classified by the EPA as health-based (a contaminant recorded above the limit the EPA tracks); the rest are monitoring or reporting violations.

What this means
A health-based violation means a contaminant was recorded above the limit the EPA tracks for it. A monitoring or reporting violation means a required test or report was late or missed — not that a contaminant was measured above a limit. “Returned to compliance” means the EPA recorded the issue as resolved.
