Nitrogen and phosphorus hydrochemistry in Las Vegas Wash by Alan Schmidt Download PDF EPUB FB2

In Las Vegas, effluents from wastewater treatment plants are discharged into Lake Mead via Las Vegas Wash (Wash). Nutrients contained in these effluents, especially nitrate and phosphate, are a concern because they could promote algal growth in Lake Mead, the region’s primary water supply.

To minimize this potential problem, several constructed wetlands have been established in various segments of the Wash. separate document “Las Vegas Wash Monitoring and Characterization Study: Results for Mercury and Selenium”. The SNWA monitored selenium and mercury, as well as traditional water quality parameters in the Las Vegas Wash mainstream and its tributaries.

The results of this study will be.

Nitrogen: Phosphorus: Nitrogen becomes available from decomposing soil organic matter. Phosphorus becomes available from decomposing soil organic matter and minerals. N is mostly available to plants as nitrate (NO 3)—a form that is very mobile in soils.

This exciting conference brings together various waste stream industries, regulators, researchers, process engineers and commercial managers, to develop a broad-based, intersectional understanding and joint projects for phosphorus and nitrogen recovery from wastewater streams, as well as reuse.

The Colorado River provides 98% of the inflow to Lake Mead, but Las Vegas Wash contributes a substantial input of total dissolved solids (TDS) and phosphorus into Las Vegas Bay, a large embayment of the Lower Basin. The TDS in Las Vegas Wash exceeds that in Lake Mead, and the inflow forms a density current in Las Vegas Bay that is detectable by conductivity by: 7.

AVAILABLE WATER SUPPLY OF THE LAS VEGAS GROUND-WATER BASIN, NEVADA By GLENN T. MALMBEBG ABSTRACT The Las Vegas ground-water basin as described in this report includes the southern part of Indian Spring Valley, Three Lakes Valley, the northern half of Ivanpah Valley, and Las Vegas Cited by: Dissolved organic nitrogen (DON) concentration was calculated by subtraction of NH 4 +-N and NO 3 −-N from the total dissolved nitrogen.

Dissolved phosphorus (DP) and total phosphorus (TP) were analyzed according to Wu et al. The E2 concentration in the sediments was measured as described by Wang et al. (a).Cited by: 5. The morphometry and hydrodynamics of Lake Mead are such that the Las Vegas Wash inflow is confined to the Lower Basin where historically it has elevated phytoplankton productivity.

However, high phosphorus loading and productivity have resulted in decreases in nitrate concentrations, and the Las Vegas Bay and parts of Boulder Basin have become nitrogen limited since Cited by: 8.

Phosphorus loads were decreased due to reductions in suspended sediment inputs. Lake Powell now retains 70% of the dissolved phosphorus and 96% of the total phosphorus inputs that once flowed into Lake Mead. The Colorado River still provides 85% of the inorganic nitrogen to Lake Mead, but Las Vegas Wash now contributes 60% of the phosphorus : Richard T.

Prentki and Larry J. Paulson. The Las Vegas Wash is the primary channel through which the Las Vegas Valley's excess water returns to Lake Mead. Contributing approximately 2 percent of the water in Lake Mead, the water flowing through the Wash consists of urban runoff, shallow groundwater, storm water and releases from the valley's four water reclamation facilities.

is the case with phosphorus. Some clay minerals may tie up small amounts of nitrogen in the ammonium form (clay fixation) but not in the same magnitude as phosphorus. Organic Nitrogen Soil organic matter is the major storehouse of many plant nutrients in soils, including nitrogen, phosphorus, sulfur, calcium and magnesium.
