How does Costa Farms compare with other water systems in Buncombe County?
By EPA's size categories, Costa Farms is a very small system (500 people or fewer). Buncombe County has 105 active public water systems. Its population served is well below the county average of 1,956 people per system, and accounts for less than 0.1% of the 205,425 people reported by systems filed under the county. Across North Carolina, the 5,087 active systems average 1,971 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Costa Farms is about half of 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. North Carolina has 311 active non-transient non-community water systems, 6.1% of the state's 5,087 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,566 North Carolina systems (90%) list groundwater as their primary source.
Who owns and regulates Costa Farms?
EPA lists Costa Farms as privately owned. The NC state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 96 of the 105 active systems in Buncombe County (91%) are also privately owned.
