Abstract : In accordance with a directive from the Colorado Department of Health, the reinjection water at the north boundary of the Rocky Mountain Arsenal will be subject to drinking water standards as established by the U. S. Environmental Protection Agency and the Colorado Department of Health (see Appendix H). In addition to organic limitations for which purpose the granular activated carbon system was installed, there is also a specific limit of 2.4 mg/l of fluoride. This directive is consistent with similar actions presently underway in many states including Arizona, California, Texas relating to fluoride in potable ground water supplies. The purpose of this study was to determine the techno-economic feasibility of the activated alumina process to remove excess fluoride from the carbon treated water. The study included data on pH and fluoride levels of the raw and treated water through two (2) exhaustion cycles of the alumina and two chemical regeneration cycles. Preliminary chemical usage, operating and capital costs are presented along with the test analytical results. (jg) Page 1
