Water quality in Oklahoma

Ada's water systems (four community systems serving roughly 32,000 people in the area) have recorded EPA violations including a Total Coliform Rule issue and a Lead and Copper Rule Revisions compliance violation, though all currently carry A/B safety grades with no active health-based violations as of the latest EPA compliance quarter. No lawsuits or specific contaminant exceedances beyond these procedural violations were found.

Afton is a small town in Ottawa County in Oklahoma's northeast corner, within the same county as the Tar Creek Superfund site — one of the most heavily contaminated former lead-zinc mining districts in the country. No EPA violation or lawsuit record specific to Afton's own water utility was found, but the town's location in this historically mined region supports a moderately elevated baseline risk estimate for heavy-metal groundwater contamination, distinct from Tar Creek's confirmed epicenter communities like Picher and Cardin.

Achille's water utility is listed by tap-water monitoring databases as having one contaminant detected above EPA health-based guidelines, though the specific substance was not identified in available records, and the utility was in compliance with federal legal limits as of the most recent EPA quarterly assessment. No lawsuits or major pollution sources were found.

No contamination finding specific to the town of Adair was confirmed (a documented E. coli boil order in early 2024 applied to Adair County Rural Water District #2, a countywide district that may or may not overlap this town's supply, and that system had returned to compliance by mid-2024). Given the ambiguity, a modest regional Oklahoma baseline is used rather than attributing the county-level incident directly to the town.

Addington is a small rural community near the Red River in southern Oklahoma. No specific EPA or state violations, lawsuits, or contamination incidents were found in research. The area's agricultural land use gives it a modest baseline risk typical of rural Oklahoma groundwater systems.

Adams is a very small, sparsely documented rural Oklahoma community with no specific EPA or state drinking-water violations found in public records searches. Oklahoma has statewide PFAS detections in 39 public water systems (9 exceeding EPA limits), but nothing ties Adams itself to a documented incident. Given typical rural-groundwater risk and no confirmed local issue, the community is scored at a modest baseline.

Adamson is served by Adamson Rural Water District #8, which was reported in full compliance with federal health-based drinking water standards as of the most recent EPA-assessed quarter. No violations, lawsuits, or specific contamination incidents were found in research. The town sits in southeastern Oklahoma outside the state's higher-risk Ogallala Aquifer and oil-field brine regions, supporting a low baseline risk estimate.
