HILLTOP MHP Water System
Consumer Confidence Report status
HILLTOP MHP 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 no open violations for HILLTOP MHP.
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.

HILLTOP MHP is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 125 people from groundwater.
As of August 1, 2026, its federal record holds 55 entries between 1993 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
All 55 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, inorganic chemicals, and the Lead and Copper Rule.

- Yes. HILLTOP MHP is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is HILLTOP MHP’s next Consumer Confidence Report due?
- HILLTOP MHP’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does HILLTOP MHP have any open drinking water violations on record?

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.
