HARPER CO RWD #1 Water System
Consumer Confidence Report status
HARPER CO RWD #1 must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show 1 item for HARPER CO RWD #1 that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Oklahoma’s official records. Always confirm current status with Oklahoma before making decisions based on this information.

HARPER CO RWD #1 is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 198 people from groundwater.
As of August 1, 2026, its federal record holds 71 entries between 2001 and 2026, of which 1 remains open; none are health-based.
Of the 71, 68 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, the Total Coliform Rules, and inorganic chemicals.

- As of August 1, 2026, EPA's federal records show 1 item for HARPER CO RWD #1 that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.
What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
