How does The Nature Conservancy compare with other water systems in Cochise County?
By EPA's size categories, The Nature Conservancy is a very small system (500 people or fewer). Cochise County has 104 active public water systems. Its population served is well below the county average of 1,253 people per system, and accounts for less than 0.1% of the 130,277 people reported by systems filed under the county. Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active transient non-community water system reports serving 144 people, so The Nature Conservancy is well below that figure.
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. Arizona has 601 active transient non-community water systems, 34% of the state's 1,769 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,612 Arizona systems (91%) list groundwater as their primary source.
Who owns and regulates The Nature Conservancy?
EPA lists The Nature Conservancy as under public/private ownership. The AZ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 28 of the 104 active systems in Cochise County (27%) are also under public/private ownership.
