Bypass systems in the <br /> <br />wash have a potential salt loading reduction of 79,000 tons <br /> <br />per year based on current flows in the wash. <br /> <br />The bypass channel has been viewed by some local <br /> <br />entities as being in conflict with nutrient control and <br /> <br />wildlife habitat improvement objectives. A planning group <br /> <br />representing various local entities, is to coordinate <br /> <br />several different waste water management activities into a <br /> <br />comprehensive plan. <br /> <br />During the time the state endeavors to set new limita- <br /> <br />tions and standards, Reclamation will continue to work with <br /> <br />the state of Nevada, the Environmental Protection Agency and <br /> <br />the local entities to resolve the issues surrounding the Wash <br /> <br />which will permit implementation of the salinity control plan <br /> <br />in concert with other alternatives for Las Vegas Wash. <br /> <br />A continuing ground water monitoring program in the <br /> <br />lower Las Vegas Valley has been augmented by the addition of <br /> <br />about 50 new wells in the Pittman area. These wells are <br /> <br />being used to verify changes in ground water levels and <br /> <br />quality before and after the abandonment of unlined waste <br /> <br />water ditches in the area. The waste water is expected to be <br /> <br />diverted to a Pittman bypass pipeline by Gctobel' 1983. The <br />curtailment of seepage from the unlined ditches is expected <br /> <br />to cause a rapid drop in ground water levels in the Pittman <br /> <br />area, resulting in reduced saline ground water inflow to Las <br /> <br />Vegas Wash.
