How does Nielsen Nissan compare with other water systems in Sussex County?
By EPA's size categories, Nielsen Nissan is a very small system (500 people or fewer). Sussex County has 476 active public water systems. Its population served is well below the county average of 425 people per system, and accounts for less than 0.1% of the 202,506 people reported by systems filed under the county. Across New Jersey, the 3,496 active systems average 2,750 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Nielsen Nissan is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. New Jersey has 637 active non-transient non-community water systems, 18% of the state's 3,496 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,313 New Jersey systems (95%) list groundwater as their primary source.
Who owns and regulates Nielsen Nissan?
EPA lists Nielsen Nissan as privately owned. The NJ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 372 of the 476 active systems in Sussex County (78%) are also privately owned.
Does Nielsen Nissan have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in September 2024. The violations listed here began between January 2017 and September 2024. By type: 8 monitoring and reporting, 3 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Lead and Copper Rule (8 of them). EPA lists 9 as resolved, 2 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
