Understanding trends in ground water contaminant concentrations is complicated by the fact that ground water quality presents complex three-dimensional trends over multiple spatial scales. To address this issue we have developed a method to jointly display three-dimensional ground water quality and topographic data. This approach allows the user to: 1) identify local areas of elevated contamina...

Emerging contaminant in drinking water has created concerns among public, water supplier and government. Pharmaceutical in water and food even in low concentration have shown potential risks to human. Acetaminophen and ibuprofen are among a set of the most prescribed drugs in the world. In this study raw water and treated drinking water from Latyan drinking water treatment facilities were analy...

Approximately 4.5 million people in the United States who rely on well water are exposed to nitrate-N concentrations exceeding the 10 mg/l standard. In this study in the Southern Willamette Valley in Oregon we reassessed nitrate-N in rural wells sampled in 2000-2001, compared nitrate-N concentrations among geological units, and surveyed residents about their perceptions of well water quality. N...

in this paper, the results of surface and ground water quality monitoring during drilling of three deep exploratory wells in geothermal project in north west of sabalan in meshkinshahr are analyzed. the region has been investigated by various researchers to generate electricity using geothermal energy. drilling in deep geothermal projects, a variety of materials such as cement, bentonite, barit...
