Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,437 Colorado systems (65%) list groundwater as their primary source.
Who owns and regulates Bristol Wsd?
EPA lists Bristol Wsd as owned by a local government. The CO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 6 of the 10 active systems in Prowers County (60%) are also owned by a local government.
Does Bristol Wsd have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2026. The violations listed here began between October 2021 and January 2026. By type: 5 monitoring and reporting, 2 contaminant level above the legal limit, 2 required treatment not met, 2 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Combined Radium (-226 and -228) (5 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.
