MT TERRACE MHP Water System

Consumer Confidence Report status

MT TERRACE 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 MT TERRACE 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 Oregon’s official records. Always confirm current status with Oregon before making decisions based on this information.

MT TERRACE MHP is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 60 people from groundwater.

As of August 1, 2026, its federal record holds 291 entries between 1993 and 2026, all of which EPA lists as closed.

Of the 291, 270 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 the Total Coliform Rules, synthetic organic chemicals, and volatile organic chemicals.
