How does Cayuga Shoreline compare with other water systems in Seneca County?
By EPA's size categories, Cayuga Shoreline is a very small system (500 people or fewer). Seneca County has 87 active public water systems. Its population served is well below the county average of 319 people per system, and accounts for less than 0.1% of the 27,760 people reported by systems filed under the county. Across New York, the 8,167 active systems average 2,374 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Cayuga Shoreline is well below that figure.
What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. New York has 5,182 active transient non-community water systems, 63% of the state's 8,167 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 241 New York systems (3%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Cayuga Shoreline?
EPA lists Cayuga Shoreline as privately owned. 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. 61 of the 87 active systems in Seneca County (70%) are also privately owned.
Does Cayuga Shoreline have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2023. The violations listed here began between August 2011 and December 2023. By type: 4 monitoring, 4 monitoring and reporting and 4 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 9 as resolved and 3 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.
