Abstract : In summary, it was concluded that: Fluoride concentrations for 15 out of 18 360 deg monitoring wells in the vicinity of the north boundary, northwest boundary, and north side of Basin F at RMA are averaging above the State of Colorado standard of 2.4 mg/1. The evaluation of this data has resulted in a range of levels between 0.763 and 7.462 mg/1. At the north boundary in the vicinity of the pilot containment/treatment system, fluoride levels average approximately 3.5 mg/1. Evaluation of the data for seasonal trends over a two-year period 75127 (1 Jun 75) to 77003 (1 Jan 77) yielded inconclusive results. Limited success was realized in the determination of temporal trends. Several wells in the vicinity of Basin F show consistent decrease of fluoride concentration with time (approximately 0.5 mg/1 per year).
