How does Orovada Water District compare with other water systems in Humboldt County?
By EPA's size categories, Orovada Water District is a very small system (500 people or fewer). Humboldt County has 27 active public water systems. Its population served is about 61% below the county average of 511 people per system, and accounts for 1.4% of the 13,801 people reported by systems filed under the county. Across Nevada, the 643 active systems average 5,508 people each. Nationally, the average active community water system reports serving 6,703 people, so Orovada Water District is well below that figure.
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. 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 Orovada Water District?
EPA lists Orovada Water District as owned by a local 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. 7 of the 27 active systems in Humboldt County (26%) are also owned by a local government.
Does Orovada Water District have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in July 2017. The violations listed here began between January 2006 and July 2017. By type: 6 monitoring and reporting, 4 contaminant level above the legal limit and 2 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 4 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.
