Ag Order 4.0 requires that the Primary Irrigation Well for each enrolled ranch be sampled between March 1 and May 31 of 2022.  The Ag Order also requires that every Domestic Well located on an enrolled ranch be sampled during this time.  After completing the registration form below, the individual(s) you designate will be contacted by one of our samplers to confirm timing, access, and other details.  Upon successful sample collection, you will need to make a payment as follows:

Primary Irrigation Wells – $160 per well
