Abstract : In accordance with a directive from the Colorado Department of Health, the reinjection water at the North Boundary of RMA will be subject to EPA and CDH drinking water standards. In response to this directive, Rubel and Hager was engaged by RMA to perform a feasibility study during September 1978. The study documented that using the activated alumina treatment method, the excess fluoride can be removed from the carbon treated water at the reinjection site. At the conclusion of the feasibility study, it was determined that further pilot testing would be necessary to optimize the caustic regeneration procedure for maximum long-term economy. Therefore, this pilot test program was established. The fluoride removal pilot test runs have demonstrated that a full scale fluoride removal water treatment plant, with raw water pH adjustment, can reliably remove 1700 grains of fluoride per cubic foot of activated alumina. Operating treatment cost projection for the full scale plant is 15/1000 gallons. Capital cost estimate for the 1000 gpm treatment system is $270,000. -BKA
