How does Big Bend compare with other water systems in Nevada?
By EPA's size categories, Big Bend is a very small system (500 people or fewer). Across Nevada, the 643 active systems average 5,508 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Big Bend is about 65% below that figure.
What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Nevada has 258 active transient non-community water systems, 40% of the state's 643 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 557 Nevada systems (87%) list groundwater as their primary source.
Who owns and regulates Big Bend?
EPA lists Big Bend as Native American-owned. The EPA Region 09 is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act.
Does Big Bend have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between December 2023 and October 2025. By type: 5 monitoring, 5 public notice, recordkeeping or other and 2 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 5 as resolved, 5 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
