Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 128 New Jersey systems (3.7%) list purchased surface water as their primary source.

Does Ridgewood Water 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 2025. The violations listed here began between June 2023 and August 2025. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Groundwater Rule (5 of them). EPA lists 8 as archived, 2 as unaddressed and 2 as resolved. 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. 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.
