Is RIVERSIDE CSA #122-MESA VERDE required to publish a Consumer Confidence Report?

Yes. RIVERSIDE CSA #122-MESA VERDE 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 RIVERSIDE CSA #122-MESA VERDE’s next Consumer Confidence Report due?

RIVERSIDE CSA #122-MESA VERDE’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.

Consumer Confidence Report status

RIVERSIDE CSA #122-MESA VERDE 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 RIVERSIDE CSA #122-MESA VERDE.

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

System facts

System ID (PWSID): CA3310028
System type: Community Water System
Population served: 766
Service connections: 330
Ownership: local government
Water source: groundwater (wells)

RIVERSIDE CSA #122-MESA VERDE is one of 728 community water systems in California in the 501 to 3,300 people size category, serving 766 people from groundwater.

As of August 1, 2026, its federal record holds 123 entries between 1980 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.

Of the 123, 10 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 inorganic chemicals, the Total Coliform Rules, and the Lead and Copper Rule.

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.
