ARROYO CENTER, Monterey County — October 2026. The Arroyo Center Water Company 2025 Consumer Confidence Report, dated May 28, 2026 and published through the California Public Utilities Commission’s report directory, gives local households access to actual drinking-water test results. The company identifies the system as CA2701658, with wells off Arroyo Seco Road near Greenfield.
Which 2025 results stand out?
For E. coli, the annual report shows zero detections and zero months in violation. Its 2025 listed values include fluoride at 0.20 parts per million (ppm), compared with a maximum contaminant level of 2 ppm; haloacetic acids at 13 parts per billion (ppb), compared with 60 ppb; and total trihalomethanes at 18 ppb, compared with 80 ppb. Those values are below the limits shown in the table. A 2025 summary does not constitute a real-time water advisory or an independent test of any particular home.
Why are the lead numbers older?
The same report displays the most recent lead-and-copper tap samples from August 2023, rather than claiming fresh 2025 lead sampling. Five customer sampling locations were listed; none exceeded the lead action level in that sampling set. The reported 90th-percentile lead result was zero ppb. Plumbing inside an individual property can affect lead at its tap, so households concerned about their own fixtures may request appropriate testing.
Other figures also come from earlier years: sodium and hardness samples are dated 2024, while several secondary-constituent results date to 2022. Readers should compare testing dates before treating any listed number as a 2025 measurement.
How to ask about the current supply
The report lists the water operator as Central Coast Water Operations, LLC at (831) 521-5221. Residents can ask for the latest notice, current sampling information and the required lead service-line inventory, which the report says was completed in 2024. The presence of a published annual drinking-water report is independent of CPUC’s separate financial reporting review; the two should not be conflated.
