Who owns and regulates Riverside Park?

Does Riverside Park have drinking water violations?

EPA's records list 9 violations for this system; 1 is health-based, and the most recent began in January 2024. The violations listed here began between January 2017 and January 2024. By type: 7 monitoring and reporting, 1 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Nitrate (4 of them). EPA lists 6 as resolved, 2 as archived and 1 as unaddressed. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
