Drinking Water Well Sampling Guidelines:
After three years of consecutive samples...
If all results are less than 8mg/L, sampling is reduced to every five years;
If sample results are between 8mg/L - 10mg/L, continue to sample annually;
If the sample exceeds 10mg/L, notification is required to the user and Regional Board, then no further sampling is required.
(Safe drinking levels are 10mg/L or less, nitrate + nitrite as nitrogen.)

ILRP-Irrigated Lands Regulatory Program
Drinking Water Well Monitoring Program
The Drinking Water Well Monitoring Program started in January 2022 in the Sac-Valley making the first drinking water well samples due by December 31, 2022. This program is administered by the Regional Water Quality Control Board. Landowners with parcels enrolled in the ILRP that have drinking water wells actively used for drinking and cooking have this requirement. The Regional Board sent postcards in August of 2023 to remind landowners to complete their well water sampling. The second sample is due by December 31, 2023. If you did not test the first go around, please do it now.
If you have any questions about this program, please contact the Regional Board at (916) 464-4611 or email@example.com
