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.
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.
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.
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.
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.
Recent study indicating nitrate and perchlorate are the primary inorganic constituents of interest here, coming from human activities such as agriculture.
Research findings and examples of application to real problems--biosolids have high concentrations of household contaminants compared to treated liquid wastewater effluent.
