Well vulnerability results from the young age of groundwater. Karst features permit contaminants to move into the aquifer easily, leading to a well mixed aquifer; geochemical processes do not degrade contaminants quickly.
Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
Estimates of uranium resources affected by land withdrawal, effects of previous breccia-pipe mining, water-chemistry data for streams and springs, and potential biological pathways of exposure to uranium and associated contaminants.
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.
