California has 3,016 active transient non-community water systems, 40% of the state's 7,479 active systems.

Who owns and regulates Snowline?

Does Snowline have drinking water violations?

EPA's records list 9 violations for this system; 1 is health-based, and the most recent began in October 2019. The violations listed here began between August 1984 and October 2019. By type: 7 monitoring and reporting, 1 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 8 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
