What the violations mean
Surface Water Treatment Rule
69 incidentsThe system did not complete a treatment step or action that the Surface Water Treatment Rule requires (a treatment technique violation).
The utility had to notify customers about each of these violations.
Revised Total Coliform Rule
20 incidentsThe system did not meet a requirement of the Revised Total Coliform Rule
Coliform and E. coli rules protect against bacteria in the distribution system
Stage 1 Disinfection Byproducts Rule
2 incidentsThe system did not meet a treatment requirement of the Stage 1 Disinfectants and Disinfection Byproducts Rule
Byproducts form when disinfectants react with natural material in water. Long-term exposure above federal limits may increase cancer risk
Where the water comes from
Grindstone Rancheria draws water from 1 surface water intake.
Annual water quality report
Grindstone Rancheria 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 Grindstone Rancheria 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 EPA Region 9.
