How does Johns Manville compare with other water systems in Camden County?

By EPA's size categories, Johns Manville is a very small system (500 people or fewer). Camden County has 101 active public water systems. Its population served is well below the county average of 2,795 people per system, and accounts for less than 0.1% of the 282,295 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 Johns Manville is about half of 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 Johns Manville?

Does Johns Manville have drinking water violations?

Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in October 2019. The violations listed here began between October 2007 and October 2019. By type: 7 contaminant level above the legal limit and 5 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 of them). EPA lists 7 as resolved and 5 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.
