Its population served is well below the county average of 1,144 people per system, and accounts for 4.4% of the 5,721 people reported by systems filed under the county. Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active community water system reports serving 6,703 people, so Ripley is well below that figure.

Homes, apartments and mobile-home parks are served by these. Illinois has 1,773 active community water systems, 46% of the state's 3,872 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 348 Illinois systems (9%) list purchased groundwater as their primary source.
Who owns and regulates Ripley?

Does Ripley have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2018. The violations listed here began between April 2002 and August 2018. By type: 7 monitoring and reporting, 3 public notice, recordkeeping or other and 2 monitoring. The contaminant or rule involved most often is Chlorine (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.
