“…Analytical results indicated that the quality of the springflow varied considerably throughout the middle Snake reach (Table 1). These results corroborate the findings from previous sampling efforts (Mann, 1989;Brockway and Robison, 1992;Mann and Low, 1995). Dissolved-solids concentrations in the springs ranged from 195 to 424 milligrams per liter (mgIL), and dissolved nitrate concentrations ranged from 0.83 to 2.8 mg/L as N. Other nitrogenous species and total phosphorus concentrations in the spring water were near or below the analytical detection level.…”

“…Because of the magnitude, location, and consistency of this recharge, the springs are a valuable economic resource for domestic, hydropower, irrigation, aquaculture, and recreational uses. Water-quality data collected from springs in the reach have shown distinct differences in the chemistry of individual springs (Mann, 1989;Brockway and Robison, 1992;Mann and Low, 1995). Mann and Low (1995) determined that the differences in chemistry between the springs in the reach were attributable to variati6ns in land and water use on the north side of the Snake River. This article describes the spatial variability in the chemical characteristics of selected springs in the middle Snake reach and evaluates the overall contribution of selected constituent loads from the springs to the loads transported in the Snake River.…”

The 150‐kilometer middle reach of the Snake River (middle Snake) in south‐central Idaho receives large quantities of water from springs discharging along the north side of the river from the regional Snake River Plain aquifer. Water‐quality samples collected from nine north‐side springs in April 1994 indicated that springs in the upstream part of the reach had larger concentrations of dissolved solids, dissolved nitrate, total nitrogen, tritium, and heavy isotopes of hydrogen and oxygen than to springs in the downstream part of the reach. Because the spring chemistry varies in the reach, discharge from the springs resulted in a degradation in water quality in some parts of the middle Snake and improvements in water quality in other parts. Depending on the annual discharge in the Snake River, the contribution from the north‐side springs represented 33 to 66 percent of the discharge, 32 to 57 percent of the dissolved solids, 26 to 50 percent of the total nitrogen, and 7 to 14 percent of the total phosphorus transported annually from the middle Snake. Synoptic sampling showed that the north‐side springs contributed 84 percent of the discharge and 35, 40, and 10 percent of the dissolved solids, total nitrogen, and total phosphorus load, respectively, to the Snake River during the peak of the irrigation season in 1994.

“…Atmospheric thermonuclear weapons testing from 1952 to the mid-1960's introduced a large amount of tritium to the atmosphere that was incorporated directly into water molecules of precipitation. Mann and Low (1994, fig. 2) calculated concentrations in precipitation at the Idaho National Engineering and Environmental Laboratory as high as 4,000 pCi/L in 1963; concentrations in precipitation have been decreasing since that time because of the short half-life of tritium and because most atmospheric thermonuclear weapons testing has been discontinued.…”

“…The distribution of stable isotope ratios and tritium concentrations in the Jerome/Gooding study area correlates well with those in springs on the southern and western margins of the area that drain the eastern Snake River Plain aquifer. Mann and Low (1994) and Clark and Ott (1996) attributed the concentrations in these springs to recharge from irrigation water upgradient from the springs. Long-term (1980-96) NO 2 +NO 3 -N data are available for two areas in the basin Blue Lakes, Briggs.…”

FOREWORDThe mission of the U.S. Geological Survey (USGS) is to assess the quantity and quality of the earth resources of the Nation and to provide information that will assist resource managers and policymakers at Federal, State, and local levels in making sound decisions. Assessment of water-quality conditions and trends is an important part of this overall mission.One of the greatest challenges faced by waterresources scientists is acquiring reliable information that will guide the use and protection of the Nation's water resources. That challenge is being addressed by Federal, State, interstate, and local water-resource agencies and by many academic institutions. These organizations are collecting water-quality data for a host of purposes that include: compliance with permits and water-supply standards; development of remediation plans for a specific contamination problem; operational decisions on industrial, wastewater, or watersupply facilities; and research on factors that affect water quality. An additional need for water-quality information is to provide a basis on which regional and national-level policy decisions can be based. Wise decisions must be based on sound information. As a society we need to know whether certain types of water-quality problems are isolated or ubiquitous, whether there are significant differences in conditions among regions, whether the conditions are changing over time, and why these conditions change from place to place and over time. The information can be used to help determine the efficacy of existing water-quality policies and to help analysts determine the need for and likely consequence of new policies.To address these needs, the Congress appropriated funds in 1986 for the USGS to begin a pilot program in seven project areas to develop and refine the National Water-Quality Assessment (NAWQA) Program. In 1991, the USGS began full implementation of the program. The NAWQA Program builds upon an existing base of water-quality studies of the USGS, as well as those of other Federal, State, and local agencies. The objectives of the NAWQA Program are to:Describe current water-quality conditions for a large part of the Nation's freshwater streams, rivers, and aquifers. Describe how water quality is changing over time.Improve understanding of the primary natural and human factors that affect water-quality conditions. This information will help support the development and evaluation of management, regulatory, and monitoring decisions by other Federal, State, and local agencies to protect, use, and enhance water resources.The goals of the NAWQA Program are being achieved through ongoing and proposed investigations of 60 of the Nation's most important river basins and aquifer systems, which are referred to as study units. These study units are distributed throughout the Nation and cover a diversity of hydrogeologic settings. More than two-thirds of the Nation's freshwater use occurs within the 60 study units and more than two-thirds of the people served by public water-supply system...

“…Concentrations of NO2+NO3 in preirrigation samples at SP6 do not indicate an increase. Numerous studies have reported distinct differences in the chemistry of individual springs discharging to the middle Snake (Mann, 1989;Brockway and Robison, 1992;Mann and Low, 1995;Clark and Ott, 1996). The differences result from differences in the source water for the spring and spatial variations in land and water use on lands under which contributing water flows.…”
