Groundwater means the system draws its water from wells or springs fed by underground aquifers. 585 Wyoming systems (75%) list groundwater as their primary source.

Who owns and regulates Lazy L and B Ranch?

Does Lazy L and B Ranch have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in June 2024. The violations listed here began between July 1991 and June 2024. By type: 9 monitoring and reporting, 1 monitoring, 1 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 8 as archived and 4 as resolved. 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. 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.
