How does Rutland Water Supply compare with other water systems in Humboldt County?
By EPA's size categories, Rutland Water Supply is a very small system (500 people or fewer). Humboldt County has 13 active public water systems. Its population served is well below the county average of 550 people per system, and accounts for 1.6% of the 7,145 people reported by systems filed under the county. Across Iowa, the 1,828 active systems average 1,718 people each. Nationally, the average active community water system reports serving 6,703 people, so Rutland Water Supply 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. Iowa has 1,084 active community water systems, 59% of the state's 1,828 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,502 Iowa systems (82%) list groundwater as their primary source.
Who owns and regulates Rutland Water Supply?
EPA lists Rutland Water Supply as owned by a local government. The IA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 11 of the 13 active systems in Humboldt County (85%) are also owned by a local government.
Does Rutland Water Supply have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in May 2017. The violations listed here began between July 1988 and May 2017. By type: 6 monitoring and reporting, 4 contaminant level above the legal limit, 1 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 9 as resolved and 3 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.
