How does Frito-Lay compare with other water systems in Windham County?

By EPA's size categories, Frito-Lay is a small system (501 to 3,300 people). Windham County has 254 active public water systems. Its population served is about 3.6 times the county average of 251 people per system, and accounts for 1.4% of the 63,868 people reported by systems filed under the county. Across Connecticut, the 2,363 active systems average 1,247 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Frito-Lay is about twice 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. Connecticut has 483 active non-transient non-community water systems, 20% of the state's 2,363 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,263 Connecticut systems (96%) list groundwater as their primary source.

Who owns and regulates Frito-Lay?

EPA lists Frito-Lay as privately owned. The CT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 220 of the 254 active systems in Windham County (87%) are also privately owned.

Does Frito-Lay have drinking water violations?

Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2025. The violations listed here began between January 2004 and January 2025. By type: 8 monitoring and reporting and 4 required treatment not met. The contaminant or rule involved most often is Groundwater Rule (4 of them). EPA lists 11 as resolved 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. 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.
