The test pumping and data collec- tio~ ~nd analysis will continue through 1981 or until adequate information is collected to dete~,~ne the pumping effects on the river and operational procedures. ~ study to investigate deep well i~jection disposal of the bri~e ~as been initiated. The stu~y ~ill be done by a private consultant and will cover techni- cel, e~vironmental, political, ane econa::::.: areas. An actual testi:)!; pro!,",,,:.

Several deep wells i~ Paradox Valley, drilled and aba~ldoned by oil companies, ~ill be strongly considered for possi21e locations of injecting. ~he proposed Radium Evaporatic~ Pend ~c~:d be located approxireate2y eight :::i:es southwest of Naturitc, C02..01"2::C' on ttvo intemittent tyi~.'..:- taries 0: Dr~ Creek.

The removal of hydrogen sulfide gas fro~ the brine is required for he31t~, safety, and operational reasons. Removal processes have been determined and are being tested. The hydrogen sulfide pilot s~ripping plant testing is approxi~ately 70 percent completed. Tl1is s~culd be completed during the oirst paY~ of 1982. Initial sizing o~ the ~ajor facilities has been oa~ec ::" 2. pumping rate of 5 cis ..... : ':2 :,rine well field. The . design data collection program will provide information for more accurately determining the pumping rate required for reducing brine inflow to the Dolores River. Hith this pumping rate, preconstruction design of all required facilities will be done. Also with the results of the deep well injection study and additional Radium Reservoir investigations, decisions will be made as to the most suitable disposal metllo~. Flood protection was provided 2lo~g the river channel throughout the valley. A rock jetty was removed and several hundred feet 0: "jackst! were built and installed to protec~ the wel~ field facilities IroD flooc damage. h1aterfowl studies to determine the impacts an evaporation pond woul~ have on waterfowl have been done by Colorado State University and Service personnel.
