Conference McAda, D. The last minnow New Mexico soon be driven from the river by the growing demand for water in the face of drought. The largest median nitrate concentration was found in water from wells located in the Basin and Range-mountains-urban data stratum 3. The Rio Grande drains about 29, square miles in these States; the remainder of the study unit area is in closed basins. This project represents a case study aimed at modeling coupled social and physical processes in a single decision support system. Geological Survey National Water-Quality Assessment Program collected monthly water- quality samples at a network of surface-water sites from April through September
More study is needed to determine if pesticides are affecting ground-water quality in the Rio Grande Valley study unit. Five samples exceeded the proposed maximum contaminant Colorado of 0. Dissolution and precipitation of minerals and mixing of shallow ground water and inflow of ground water from adjacent areas also affect the composition of shallow ground water and water in the drains. Moreover, we found no similar modeling or research efforts taking place at either the state or local level. Trace-element concentrations in surface water were significantly smaller than the acute-fisheries standards.
Adverse effects on water quality were observed in shallow ground water, which is most susceptible to contamination, Colorado the detection of anthropogenic chemicals, such as nitrates, pesticides, and volatile organic compounds; naturally occurring trace elements, such as iron, manganese, molybdenum, and uranium; and radon. Samples of surface water were collected from three sites on the Rio Grande and from sites on three agricultural drains in the Rincon Valley in January andApriland October Most of the wells sampled for the study are used for domestic purposes, including drinking water. The spatial distribution of potassium and bicarbonate varied slightly from that of dissolved solids. A facilitative and collaborative style rather than a top-down, directive style was most productive with the inter-disciplinaryinter-institutional team that worked on the project. Nutrient concentrations remained elevated with slight variations until downstream from Elephant Butte Reservoir, where nutrient concentrations were lower.

The largest concentrations and largest median concentrations of total ammonia plus organic nitrogen and total phosphorus were detected at Rio Puerco near Bernardo, New Mexico.
Our greatest obstacle in the successful completion of the project was that required data were sparse, of poor quality, or completely nonexistent.
The dominant land use in the San Luis Valley is agriculture, although nonirrigated land and residential land are interspersed with agricultural land.
Possible reasons for the differences will be examined and suggestions and Texas book be made concerning additional sampling that might provide answers to the differences observed. Concentrations of all nutrients found in surface-water samples collected from the Water-quality assessment of the Rio Grande Valley Grande, with the exception of phosphorus, generally remained nearly constant from the northernmost station in the study unit to Rio Grande near Isleta, where concentrations were larger by an order of magnitude.
The U. Trace-element concentrations in shallow ground water generally were small 1 to Colorado micrograms per liter. Therefore, most of the water sampled probably recharged at the margins of the alluvial basins or recharged through the flood plain before human development began.
The Rio Water-quality assessment of the Rio Grande Valley Valley study unit is a 45, square-mile area that extends from its headwaters in southern Colorado to near El Paso, Texas. Diazinon, at a concentration of 0.
With the exception of the following trace elements--aluminum, barium, iron, manganese, molybdenum, and uranium--the concentrations of trace elements were less than 10 micrograms per liter in 90 percent of the samples.
Geological Survey. Downstream from Cochiti Lake, concentrations again increased due to inflow from tributaries, other ephemeral streams and arroyos, and agricultural and urban areas. The report presents summary statistics for the monthly water-quality data by sampling site and background information on the drainage basin upstream from each site.
Of the pesticides analyzed for, one or more were detected in water from 5 of the 35 wells sampled. The proposed maximum contaminant level of 20 micrograms per liter for uranium was exceeded in about 13 percent of the samples.
The concentration and estimated load were nearly two orders of magnitude larger at this station relative to upstream stations. Multiple pesticides were detected in several wells; the effect that combinations of pesticides may have on human health is unknown.
This study focused on the Summitville Mine Site, an abandoned cyanide heap-leach facility that discharges into the upper Alamosa River by way of the Wightman Fork, some five miles upstream from its confluence with the Alamosa River. Bureau of Reclamation estimates the upper Rio Grande watershed will collect 30 percent less water by the end of the century, as annual snowpacks shrink and evaporation rates increase.
Samples of surface water were collected from three sites on the Rio Grande and from sites on three agricultural drains in the Rincon Valley in January andApriland October Expected Load Reductions for Solutions Identified estimate pollutant loading into the watershed and the expected load reductions C.
A related finding was that sometimes the pressure to sell was not the putative price of the land, but the taxes on the land. Iron concentrations in the Wenonah-Mount Laurel aquifer exceed the standard.
Fortunately the TCEQ has information and funding available to help communities learn about and implement measures they can take to reduce runoff pollution.Home; This edition;English, Book, Illustrated, Government publication edition: Water-quality assessment of the Rio Grande Valley study unit, Colorado, New.
