New York has 704 active non-transient non-community water systems, 8.6% of the state's 8,167 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 7,096 New York systems (87%) list groundwater as their primary source.

Who owns and regulates Casella Waste Services?

The NY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 183 of the 229 active systems in St. Lawrence County (80%) are also privately owned.

Does Casella Waste Services have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2023. The violations listed here began between April 2018 and July 2023. By type: 11 monitoring and reporting and 1 monitoring. The contaminants or rules involved are Revised Total Coliform Rule, Lead and Copper Rule, 2,4,5-TP (Silvex) and Endrin. EPA lists 10 as archived 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. 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.
