Regional nitrate and pesticide trends in ground water in the eastern San Joaquin Valley, California.
Protection of ground water for present and future use requires monitoring and understanding of the mechanisms controlling long-term quality of ground water. In this study, spatial and temporal trends in concentrations of nitrate and pesticides in ground water in the eastern San Joaquin Valley, California, were evaluated to determine the long-term effects of agricultural and urban development on...
متن کاملSocial Disparities in Nitrate-Contaminated Drinking Water in California’s San Joaquin Valley
BACKGROUND Research on drinking water in the United States has rarely examined disproportionate exposures to contaminants faced by low-income and minority communities. This study analyzes the relationship between nitrate concentrations in community water systems (CWSs) and the racial/ethnic and socioeconomic characteristics of customers. OBJECTIVES We hypothesized that CWSs in California's Sa...
متن کاملAnalysis of ozone in the San Joaquin Valley of California
The dynamics of ozone in the San Joaquin Valley of central California are studied by systematic diagnostic runs of the three-dimensional SARMAP Air Quality Model. Air quality in the San Joaquin Valley is the result of a complex combination of local and transported emissions. Simulations show that relatively brisk winds at points of in#ow to the Valley produce a strong dependence of ozone in the...
متن کاملSustainability of irrigated agriculture in the San Joaquin Valley, California.
The sustainability of irrigated agriculture in many arid and semiarid areas of the world is at risk because of a combination of several interrelated factors, including lack of fresh water, lack of drainage, the presence of high water tables, and salinization of soil and groundwater resources. Nowhere in the United States are these issues more apparent than in the San Joaquin Valley of Californi...
متن کاملGroundwater salinity in the southern San Joaquin Valley
Water salinity in the San Joaquin Valley is a function of depth, location, and stratigraphy. This paper presents a reconnaissance study of water salinity within Kern County, California, using chemical analyses from oil field produced water and water wells as well as geophysical logs. Log analysis indicates that the base of underground sources of drinking water (USDWs) (<10,000 mg/L) slopes from...
