How does Cushing Water Supply compare with other water systems in Woodbury County?
By EPA's size categories, Cushing Water Supply is a very small system (500 people or fewer). Woodbury County has 32 active public water systems. Its population served is well below the county average of 3,110 people per system, and accounts for 0.2% of the 99,514 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 Cushing 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 Cushing Water Supply?
EPA lists Cushing 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. 20 of the 32 active systems in Woodbury County (63%) are also owned by a local government.
Does Cushing 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 October 1999. The violations listed here began between September 1978 and October 1999. By type: 8 monitoring and reporting and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Nitrate (8 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.
