Database provides information on petroleum reservoirs, type and abundance of constituents dissolved in produced water, geochemical reactions between the water and rock, hydrology and geologic, spatial distribution of petroleum production areas.
Report on the use of regression equations from measurements made by water quality monitors and analytical results of manually collected samples estimating nutrient, bacteria, and other constituent concentrations to study streams in Kansas.
Summarizes measurements of ground-water chemistry that affect the vulnerability of aquifers to contamination. Data are from aquifers throughout the conterminous US and Alaska.
Sulfate deposition to high-elevation areas has decreased here as a result of reductions in SO2 emissions. Nitrate deposition did not change, whereas ammonium deposition increased, particularly at sites near urban and agricultural areas.
Site on the Chlorofluorocarbon Laboratory and its analytical services for CFCs, sulfur hexafluoride, dissolved gases including nitrogen, argon, methane, carbon dioxide, oxygen, and helium, and tritium/helium-3 dating.
Short descriptions of the research and monitoring activities we are carrying out to assist state, local, and Federal agencies dealing with water resource issues in the southern part of the state.
Characterize the quality of selected rivers and aquifers used as a source of supply to community water systems in the United States to determine the occurrence of about 280 primary unregulated anthropogenic organic compounds.
