Consultants urge measured approach to replacing surface irrigation; warn on groundwater limits
Summary
Jones & DeMille consultants recommended short‑term well rehabilitation, sediment diversions and a phased booster‑station plan rather than wholesale conversion to groundwater, noting some wells have radionuclide test results above EPA limits.
Consultants presented options for Beaver City's secondary (pressurized irrigation) system after surface water was compromised by fire‑related debris. They recommended prioritizing river diversion and sediment handling structures and temporarily rehabbing existing wells before considering large‑scale groundwater drilling.
The consultants warned against over‑reliance on groundwater: "the Center Street well had exceeded the the maximum contamination level for radionuclides set by the EPA," one presenter said, explaining why some wells remain out of the culinary system and why groundwater substitution carries quality and sustainability risks. The consultants suggested a mix of sediment handling, temporary well rehabilitation to provide limited additional flow, and designing any future wells to culinary standards where feasible.
Council discussed the tradeoffs between acting quickly this season and conducting measured planning to avoid long‑term water‑quality and aquifer‑sustainability problems. Staff will pursue eligible funding pools and coordinate next steps with FEMA, NRCS, USDA, and state drinking water programs.
