Shallow Ground Water in the Whitney Area, Southeastern Las Vegas Valley, ClarkCounty, Nevada. Part 2. Assessment of a Proposed Strategy to Reduce the Contribution of Salts to Las Vegas Wash

摘要

A continuing increase in the contribution of dissolved solids to Las Vegas Washfrom various sources, including ground-water seepage, has resulted in the proposal of several salt-reduction strategies. One such strategy is the construction of an impoundment, or detention basin, consisting of a dike structure above ground and a slurry wall beneath the dike that would extend to the base of the shallow alluvial aquifer. The report describes the results of a study made to determine whether the proposed slurry wall could be effective in inhibiting saline ground water from seeping to the wash under various possible
