Science and Products
Evaluating chloride trends due to road-salt use and its impacts on water quality and aquatic organisms
Chloride, a key component of road salt, is soluble, highly mobile in water, and, at high concentrations, can be toxic to aquatic vegetation and wildlife. USGS scientists have been analyzing temporal, seasonal, and environmental trends in chloride concentrations across the U.S. to determine the effects that road salt may be having on water quality and aquatic organisms.
Beach health in Wisconsin
Beach water-quality (beach health) data are collected for both coastal and inland Wisconsin beaches. These data are collected and analyzed by multiple agencies throughout Wisconsin including local health departments, universities, state agencies, and federal agencies including the USGS.
Environmental factors and risk estimation for waterborne pathogens at three Great Lakes beaches
The goals of this study were to quantify pathogen concentrations in water at three Lake Michigan beaches, identify environmental factors that influence pathogen occurrence and variability, and to estimate health risks for recreational swimmers.
