What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Nevada has 224 active community water systems, 35% of the state's 643 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 60 Nevada systems (9.3%) list purchased surface water as their primary source.
Who owns and regulates Nellis Air Force Base?
EPA lists Nellis Air Force Base as owned by the federal government. The NV state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 17 of the 141 active systems in Clark County (12%) are also owned by the federal government.
Does Nellis Air Force Base have drinking water violations?
Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in July 2025. The violations listed here began between July 1991 and July 2025. By type: 9 contaminant level above the legal limit, 1 required treatment not met, 1 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 10 as resolved and 2 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.
