How does Stockport Water Supply compare with other water systems in Van Buren County?
By EPA's size categories, Stockport Water Supply is a very small system (500 people or fewer). Van Buren County has 7 active public water systems, and Stockport Water Supply is the 6th-largest of them by population served. Its population served is about 40% below the county average of 456 people per system, and accounts for 8.5% of the 3,195 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 Stockport 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. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 119 Iowa systems (6.5%) list purchased surface water as their primary source.
Who owns and regulates Stockport Water Supply?
EPA lists Stockport 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. 7 of the 7 active systems in Van Buren County (100%) are also owned by a local government.
Does Stockport Water Supply have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 2020. The violations listed here began between October 1985 and December 2020. By type: 7 monitoring and reporting, 3 monitoring, 1 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (3 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.
