<br />l\.) <br />CJ1 <br />w <br />~ <br /> <br />569, or other measures that reduce salinity in the lower <br /> <br />mainstem of the Colorado River, are presented in the <br /> <br />paragraphs that follow. <br /> <br />A complete description of the <br /> <br />projects can be found in the "1984 Review - Water Quality <br />Standards for Salinity - Colorado River System," May 1984. <br /> <br />Paradox Valley Unit (Reclamation) - On June 19, 1986, a <br /> <br />construction contract was awarded to Fenix and Scisson, Inc., <br /> <br />of Tulsa, Oklahoma to drill the 15,400 foot Injection Test <br /> <br />Well No.1, Paradox Valley. <br /> <br />The notice to proceed with <br /> <br />construction was given on July 9, 1986. The contractor is <br /> <br />building access roads and preparing the drill site and <br /> <br />anticipates the initiation of drilling by the end of the <br /> <br />calendar year. The total estimated value of the contract is <br /> <br />$16,300,000, slightly lower than Reclamation's estimate. <br />When completed, it will be one of the world's deepest brine <br /> <br />injection wells. A special, high corrosion resistant alloy, <br /> <br /> <br />brine injection tube will be used in the well. Monitoring of <br /> <br /> <br />flow and conductivity of the Dolores River and the ground <br /> <br />water continues, as do brine interface readings, and water <br /> <br />table measurements. <br /> <br />When positive test results are obtained, the original <br /> <br />Definite plan Report will be amended and the National <br />Environmental policy Act (NEPA) requirements will be <br />fulfilled. Construction of the permanent facilities will <br /> <br />then follow the approval of the amended plan. Construction <br /> <br /> <br />of the test well should be completed by 1989. <br /> <br />-7- <br />
