What the violations mean
Nitrate
29 incidentsNitrate exceeded the federal limit
High nitrate is especially dangerous for infants under 6 months and can cause blue baby syndrome
Selenium
12 incidentsTest results for Selenium were above the federal limit (a maximum contaminant level violation).
The utility had to notify customers about each of these violations.
Haloacetic Acids (HAA5)
6 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Long Term 2 Enhanced Surface Water Treatment Rule
1 incidentThe system failed required surface water treatment or filtration standards
Untreated or inadequately treated surface water can contain bacteria and viruses
Interim Enhanced Surface Water Treatment Rule
1 incidentThe system did not meet a filtration or treatment requirement for surface water
Inadequate treatment of surface water can let pathogens such as Cryptosporidium and Giardia through
Where the water comes from
Pauma Valley Water Company draws water from 8 wells.
Annual water quality report
Pauma Valley Water Company must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.
Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Pauma Valley Water Company for a copy.
Find a posted report with EPA's Consumer Confidence Report search
Testing your own water
To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by California.
