How does Tripp compare with other water systems in Hutchinson County?
By EPA's size categories, Tripp is a small system (501 to 3,300 people). Hutchinson County has 4 active public water systems, and Tripp is the 4th-largest of them by population served. Its population served is about 44% below the county average of 1,021 people per system, and accounts for 14% of the 4,085 people reported by systems filed under the county. Across South Dakota, the 699 active systems average 1,387 people each. Nationally, the average active community water system reports serving 6,703 people, so Tripp 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. South Dakota has 510 active community water systems, 73% of the state's 699 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 431 South Dakota systems (62%) list groundwater as their primary source.
Who owns and regulates Tripp?
EPA lists Tripp as owned by a local government. The SD state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 4 of the 4 active systems in Hutchinson County (100%) are also owned by a local government.
Does Tripp have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2006. The violations listed here began between August 1996 and January 2006. By type: 8 monitoring and reporting, 3 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 6 as resolved and 6 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.
