How does Countryside Estates compare with other water systems in Kent County?

By EPA's size categories, Countryside Estates is a very small system (500 people or fewer). Kent County has 136 active public water systems. Its population served is well below the county average of 1,201 people per system, and accounts for less than 0.1% of the 163,362 people reported by systems filed under the county. Across Delaware, the 494 active systems average 2,238 people each. Nationally, the average active community water system reports serving 6,703 people, so Countryside Estates is well below that figure.

What does “community water system” mean?

A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Delaware has 219 active community water systems, 44% 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 Countryside Estates?

EPA lists Countryside Estates 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. 118 of the 136 active systems in Kent County (87%) are also privately owned.

Does Countryside Estates have drinking water violations?

Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in December 2024. The violations listed here began between July 2001 and December 2024. By type: 6 public notice, recordkeeping or other, 5 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Consumer Confidence Rule (6 of them). EPA lists 10 as resolved and 2 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.
