How does Harvel compare with other water systems in Montgomery County?

What does “community water system” mean?

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. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.
Who owns and regulates Harvel?
EPA lists Harvel as owned by a local government. The IL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 16 of the 24 active systems in Montgomery County (67%) are also owned by a local government.
Does Harvel have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in July 2023. The violations listed here began between July 1998 and July 2023. By type: 5 monitoring and reporting, 3 public notice, recordkeeping or other, 3 required treatment not met and 1 contaminant level above the legal limit. 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.
