Irrigation Water Nitrate Analysis - Zone 5

Irrigation Water Nitrate Analysis - Zone 5

Wednesday, May 27, 2020
Operators within a management zone that has been designated a Phase III Management Zone must have their irrigation water tested for nitrates at least once every three years. Presently, Zone 5 is the only management area in Phase III Management. Zone 5 includes Waco, New York, Lockridge, Bradshaw, Beaver, and Leroy townships.

Irrigation wells in Zone 5 must be sampled again by April 1, 2023.

Note: The latest three-year cycle ended April 1, 2020. Operators who did not submit samples were given an extension, due to 2019 being a short irrigation season. Letters were mailed to those not in compliance with our rules and regulations. Failure to submit samples will result in a violation of the district’s rules and regulations.

Important things to remember:
  • All active wells in Zone 5 must be sampled
  • Commingled wells need to be sampled individually.
  • Follow sampling instructions, especially the time frame for delivery.
  • If there are multiple wells per quarter, be specific when labelling – sub-quarter or physical location description is helpful to assign results and therefore, comply with rules and regulations.

The Upper Big Blue NRD is now utilizing database software that will allow staff to better track reporting information, such as phase reports, sensor reports, and water samples. During this next three-year cycle, Zone 5 wells that have not been sampled by April 1, 2023, will be found in violation of district rules and regulations.
