Aesthetic measurements from Alpaugh Community Services District Consumer Confidence Report.
Aesthetic measurements are reported by the utility from its annual sampling. EPA Secondary MCLs are advisory thresholds — values outside them indicate aesthetic concerns such as taste or appearance, not health violations. Federal contaminant testing is shown in the sections above.
Notable events and violations
This section summarizes events the utility chose to disclose in its most recent Consumer Confidence Report, plus any federal compliance violations the utility recorded against itself. Both lists are utility-authored — ZipCheckup does not audit, judge, or reorder them.
Federal compliance violations on record
These entries are taken verbatim from the utility's CCR violations section. EPA defines four broad violation categories: Maximum Contaminant Level (MCL), Treatment Technique (TT), Monitoring & Reporting (M&R), and Public Notification (PN).
-
MCL · ArsenicDate not published
Our system does not meet the MCL for Arsenic. Some people who drink water containing arsenic in excess of the MCL over many years may experience skin damage or circulatory system problems, and may have an increased risk of getting cancer. We are looking into options to do away with the arsenic, one being to drill new wells or to locate other wells in the area that do not have the arsenic levels we do. The other options are systems that filter the arsenic out of the water.
-
MCL · ColorDate not published
Our system is over the MCL in color in water. The secondary standards cover the constituents in the water that affect the aesthetics of the water, in order to keep an acceptable quality. There is no health effects language for secondary standards.
