(NCC) received your letter dated March 10, 2025 for the Notice of <br /> Citizen Complaint, CT-4. <br /> We have reviewed the information provided and are providing information on the existing groundwater <br /> monitoring wells showing the readings over the last couple months in 2025 and the last quarter of 2024 <br /> where groundwater levels have come down several feet below last years levels at this time so the <br /> groundwater is not causing the surface soils to be saturated. The last reading on March 4, 2025 <br /> showed the groundwater level at 5 feet or more below the surface in monitor wells Z-1 and Z-2 which <br /> are located on the property the tenant farmer is leasing. <br /> We have also provided soil tests for the topsoil in this area for the NCCI Pit #1 from 2015 and the <br /> Bennett Pit which is north of this location from 2019, 2021, and 2022 where alkali and high salts have <br /> been present and are still present in the soils along the South Platte River and Little Dry Creek. The <br /> high salts did not just occur but have been part of the topsoil in this area for years. <br /> We appreciate your consideration of this response. <br /> Please feel free to contact me with any questions or comments. <br /> Sincerely, <br /> , e. <br /> J.C.
