Branch of chemistry that deals with the elements and compounds in water.
Characterizing contaminant concentrations with depth by using the USGS well profiler in Oklahoma, 2003-9 [ More info] Use of specialized sampling equipment to study public water supply wells, with examples showing Arsenic in two aquifers.
Chloride control and monitoring program in the Wichita River Basin, Texas, 1996-2009 [ More info] Chloride concentrations in this river have historically been high due to natural saltwater springs and seeps from geologic formations. We monitor the water to help assess the progress of human efforts designed to mitigate this problematic salinity.
Evaluation of fecal contamination by human and ruminant sources in upper Fountain Creek, Colorado, 2007-2008, by using multiple lines of evidence: [ More info] Microbial source tracking analysis of water sampled supports the argument that birds are the primary source of fecal contamination during the warm season.
Framework for Assessing the Sustainability of Monitored Natural Attenuation [ More info] Research findings and examples of application to real problems--When can natural processes to reduce, or even destroy, contaminants at toxic waste sites be relied on?
Great Lakes Beach Health Initiative [ More info] Research and development efforts to improve our ability to provide scientific information needed by local beach managers faced with questions about environmental quality and possible beach closure or resource usage.
Ground-water flow and other computer simulations for Utah [ More info] Identifies computer models in USGS publications developed to study ground water for many areas of Utah.
Groundwater Quality in the Central Eastside San Joaquin Valley, California [ More info] Summary of a detailed study in this agricultural area.
Groundwater Quality in the Kern County Subbasin, California [ More info] Arsenic was the trace element most frequently present at high concentrations here. High concentrations of arsenic result from the interaction of groundwater with naturally occurring minerals.
Groundwater Quality in the Southeast San Joaquin Valley, California [ More info] Arsenic and nitrate are the constituents found most commonly at high concentrations in the primary aquifers. Arsenic comes from natural sources and is affected by pH and dissolved oxygen.
Groundwater quality in Coachella Valley, California [ More info] Five trace elements with human-health concerns were detected at high concentrations: arsenic, boron, fluoride, molybdenum, and strontium. Vanadium was present at moderate concentrations.
