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. 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 Roark Estates Water Assoc?

Does Roark Estates Water Assoc have drinking water violations?
Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in September 2025. The violations listed here began between July 2016 and September 2025. By type: 7 required treatment not met, 2 reporting, 2 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Groundwater Rule (6 of them). EPA lists 11 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.
