Source water assessment from TOWN OF OXFORD Consumer Confidence Report:

The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants.

ZipCheckup note: this paragraph is the utility's own description of land uses and natural conditions in the watershed or aquifer feeding this system. It identifies potential contamination sources upstream of treatment. Routine treatment, federal monitoring, and the contaminant testing shown in the section above are what determine whether your tap water meets safety standards — not the assessment itself.

Treatment regime

How this utility classifies its treatment process and what each reported treatment chemical does.
