Per Ag Order 4.0, ALL on-farm domestic wells must be sampled in March-May of 2022.  The samples must be analyzed by an ELAP-certified laboratory, and reported directly to GeoTracker.  Well owners/operators must also provide laboratory results to well users within 3 days of receipt.

Preservation, Inc. will assist our members with on-farm domestic well sampling in 2022.  We have negotiated group rates for sample collection, lab analysis, and GeoTracker reporting.  Please look for an email notification in January, 2022 to sign up for sampling. 

Per Ag Order 4.0, the primary irrigation well from EVERY ranch must be sampled in March-May of 2022.  The samples must be analyzed by an ELAP-certified laboratory, and reported directly to GeoTracker.

In 2022 and 2023, those growers required to submit TNA (Total Nitrogen Applied) reports must provide the nitrate concentration from their primary irrigation well.  Only growers required to report TNA under the previous Ag Order (3.0) are required to report TNA in 2022/2023.

Samples collected to meet the above “Irrigation Well Sampling Requirements” will also meet the TNA reporting requirement for the subsequent year.  However, since the 2022 TNA reporting deadline is March 1^st, growers must use a previously-collected well sample to complete this section of the TNA report in 2022.  Subsequently, growers can use the 2022 primary irrigation well sample to complete the TNA report that is due by March 1^st of 2023.
