Groundwater quality in the Mojave area, California [More info]
Six elements with human-health concerns were detected at high concentrations: arsenic, boron, fluoride, molybdenum, strontium, and vanadium. Lead was present at moderate concentrations.
Groundwater quality in the Monterey Bay and Salinas Valley groundwater basins, 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 Northern Sacramento Valley, California [More info]
Results of a survey of contaminants in untreated groundwater in this area, separating inorganic from organic constituents.
Groundwater quality in the Northern San Joaquin Valley, California [More info]
Arsenic and boron were the trace elements that most frequently occurred at high concentrations. Fumigants (pesticides) were detected at high concentrations in 3% of the primary aquifers. Herbicides and insecticides were detected at low concentrations.
Groundwater quality in the Owens Valley, California [More info]
Trace elements boron, arsenic, and molybdenum were found at high concentrations in 15% of primary aquifers in this area.
Groundwater quality in the San Diego Drainages Hydrogeologic Province, California [More info]
Vanadium and boron were detected at high and moderate concentrations in this area. High concentrations for these constituents were detected almost exclusively in samples collected in the Temecula Valley study area.
Groundwater quality in the San Fernando--San Gabriel groundwater basins, California [More info]
Organic solvents are the chief concern in this area, which has given rise to a systematic program of monitoring and water treatment. This study shows relatively recent results.
Groundwater quality in the San Francisco Bay groundwater basins, California [More info]
The constituent present at high concentrations in the greatest proportion of the primary aquifer system was TDS, which is an indicator of salinity. Perchlorate was also present at moderate concentration in 42% of samples.
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 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.
