The DEQ received notification of water quantity and quality issues on August 11, 2017 for two existing and two deeper, replacement private domestic wells located 18 miles northeast of the Town of Moorcroft, Wyoming. The two existing domestic wells which had previously produced a good quantity of water had gone dry and the two deeper replacement wells had identified low pH (< 4 s.u.) in them.
A public meeting was held on October 12, 2017 in the Town of Moorcroft to answer questions on the recent water quality/quantity issues. In addition, a survey was distributed to identify well owners that may have noted potential water quality issues and to solicit access to sample those wells.
The study area is shown on the “Study Area” figure at the link below. The study area encompasses the majority of private domestic and stock wells and several springs that DEQ identified for sampling.
DEQ mobilized water sampling crews to the study area on October 25, 2017. A total of 55 locations were sampled and analyzed for the analytes identified in the Gillette Madison Well Field Private Water Well Sampling List (Click here to view). Of the 55 locations, 32 were domestic wells, 12 were identified as domestic/stock wells, 10 were stock wells and one location was a spring. All private well owners were provided with their water quality results.
Based on Workgroup #3 meetings in April 2018 and after review of the data from the 2017 private water well sampling, a number of potential data gaps were identified by workgroup members and the consultant. To address these data gaps the DEQ collected additional samples from 13 previously sampled water wells and one spring, collected initial samples from 5 additional water wells in accordance with the October 2017 sampling list, collected 3 surface water samples (2 stream samples and one spring), and measured water levels in conjunction with the State Engineer’s Office on sampled water wells (if accessible).
The DEQ has released its final report into low pH and low water conditions reported in the vicinity of the City of Gillette’s Madison wellfield in Crook County.
