How does Dowville Tract Association compare with other water systems in Fresno County?
By EPA's size categories, Dowville Tract Association is a very small system (500 people or fewer). Fresno County has 328 active public water systems. Its population served is well below the county average of 3,205 people per system, and accounts for less than 0.1% of the 1,051,276 people reported by systems filed under the county.

What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. California has 3,016 active transient non-community water systems, 40% of the state's 7,479 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 105 California systems (1.4%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Dowville Tract Association?
EPA lists Dowville Tract Association as privately owned. The CA 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 328 active systems in Fresno County (67%) are also privately owned.
Does Dowville Tract Association have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2021. The violations listed here began between July 2007 and August 2021. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 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.
