Branch of chemistry that deals with the elements and compounds in water.
Groundwater quality in the Santa Clara River Valley, California [ More info] This study of untreated groundwater indicates the number of samples in which inorganic or organic constituents occur in high or moderate in concentration. The study does not indicate significant problems in groundwater quality here.
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 the Southern Sacramento Valley, California [ More info] Results of a survey of contaminants in untreated groundwater in this area. Arsenic and boron were the trace elements occurring most frequently at high concentrations.
Groundwater quality in the Southern Sierra Nevada, California [ More info] Recent study indicating inorganic constituents as the primary items of concern in this area. Chemical and mineralogical compositions of the aquifer rocks probably explain variation among localities here.
Groundwater quality in the Tahoe and Martis Basins, California [ More info] Recent study encountered occasional high values of radioactive trace elements, but the water quality in this area as monitored compares favorably to more urban areas studied by the same group.
Groundwater quality in the Upper Santa Ana Watershed study unit, California [ More info] Recent study indicating nitrate and perchlorate are the primary inorganic constituents of interest here, coming from human activities such as agriculture.
Groundwater quality of southeastern Wyoming [ More info] Explains how we assess groundwater quality here, what characteristics are important, and how they hurt or, in some cases, help use use the water.
Household Chemicals and Drugs Found in Biosolids from Wastewater Treatment Plants [ More info] Research findings and examples of application to real problems--biosolids have high concentrations of household contaminants compared to treated liquid wastewater effluent.
Maps of the distribution and occurrence of ground water quality constituents and early 1970's land use in New Jersey [ More info] Links to maps of New Jersey showing nitrate levels, pesticides, Total Volatile Organic Compounds (VOCs), and radium in wells and land use of the 1970s.
