The principal ground-water quality problems in the Santa Ana River basin, as determined from two samplings ( and ), are high concentrations of dissolved solids in general and nitrate-nitrogen in particular. The distribution of dissolved solids exceeding milligrams per liter was smaller in area in than in nitrate-nitrogen concentrations as water flows downstream or percolates to groundwater.
In the area of the Santa Ana River that overlies the Chino -South GMZ, the Regional Board has determined that 50% of the nitrogen measured at the surface is lost as the water seeps beneath the streambed and into the groundwater.

Ayers R.S. and Westcot D.W. Water quality for agriculture. Two numerical models, one for the vadose zone and the other for the aquifer system, are utilized to predict nitrate pollution potential in groundwater. Transport by dispersion and convection of mobile species of nitrogen, ammonium ion exchange, first order nitrogen transformations, and nitrogen plant uptake are included in the formulation for the vadose zone.

Existing regional budgest have been used both to study groundwater nitrate pollution and to help identify local ecosystems that are important on a land-use basis but that are poorly described biogeochemically.
Avoidable problems common to many budgets include inappropriate compartment components, inadequate documentation, and unjustified certainty.
Nitrate and perchlorate are inorganic chemicals with natural and anthropogenic sources, but in the Upper Santa Ana Watershed, both enter groundwater. Introduction Environmental setting. Groundwater is the main source of water supply in the Bunker Hill, Lytle, Rialto, and Colton groundwater subbasins of the Upper Santa Ana Valley Groundwater Basin (Duell and Schroeder,Woolfenden and Kadhim, ), and it is actively managed to control the concentrations of nitrate and total dissolved solids (TDS) (Danskin et al., ).
Bernardino area (Scott, ). San Bernardino is in the upper part of the Santa Ana River drainage basin, within the Inland Basin. Widespread irrigation began in (Scott, ) and by the s, large tracts of land were dedicated to citrus and other crops, and diversions from the Santa Ana River and other streams were common.
The Upper Santa Ana Watershed Study Unit. The Upper Santa Ana Watershed study unit covers approximately 1, square miles. Within this study unit, the San Jacinto and Elsinore groundwater basins each constituted a.
study area, and the nine subbasins of the Upper Santa Ana Valley groundwater basin were. Concentrations and temporal changes in concentrations of nitrate and total dissolved solids (TDS) in groundwater of the Bunker Hill, Lytle, Rialto, and Colton groundwater subbasins of the Upper Santa Ana Valley Groundwater Basin were evaluated to identify trends and factors that may be affecting trends.
One hundred, thirty-one public-supply wells were selected for analysis based on the. Nitrate pollution in groundwater is a widespread water quality problem that can pose serious health risks to pregnant women and infants if consumed at concentrations above the Maximum Contaminant Level (MCL) of 45 milligrams per liter (mg/L) nitrate as nitrate.
Nitrate contaminated groundwater can be found in many areas of California, but is a particularly significant concern in the Tulare Lake Basin. High concentrations of nitrate in groundwater are usually due to human activities, however, some nitrate (low mg/l) is naturally occurring in arid soils (Graham, et.
al., ). Large portions of aquifers within the Salt River Valley, areas in Glendale, Mesa, Chandler and Phoenix, contain groundwater with nitrate concentrations high enough to.

78 p.The discharge of the Santa Ana River, measured below Prado Dam located mi downstream of the study area, is about equal to the total flow from wastewater-treatment facilities upstream (Hamlin and others, ).
