How does Summit Aviation compare with other water systems in New Castle County?

By EPA's size categories, Summit Aviation is a very small system (500 people or fewer). New Castle County has 76 active public water systems. Its population served is well below the county average of 7,119 people per system, and accounts for less than 0.1% of the 541,043 people reported by systems filed under the county. Across Delaware, the 494 active systems average 2,238 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Summit Aviation 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. Delaware has 82 active non-transient non-community water systems, 17% of the state's 494 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 459 Delaware systems (93%) list groundwater as their primary source.

Who owns and regulates Summit Aviation?

EPA lists Summit Aviation as privately owned. The DE state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 54 of the 76 active systems in New Castle County (71%) are also privately owned.

Does Summit Aviation have drinking water violations?

Of the 12 most recent violations in EPA's records, 11 are health-based, and the most recent began in July 2024. The violations listed here began between July 1994 and July 2024. By type: 9 contaminant level above the legal limit, 2 required treatment not met and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 of them). EPA lists 6 as resolved and 6 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.
