Bakken Shale unconventional oil and gas production has not caused widespread hydrocarbon contamination to date in groundwater used for water supply

Our surface water, groundwater, and aquatic ecosystems are priceless resources, used by people across the Nation for drinking, irrigation, industry, and recreation. The National Water-Quality Assessment (NAWQA) Project is a leading source of scientific data and knowledge for development of science-based policies and management strategies to improve and protect our water resources.

Surface-water nutrient and sediment mappers are now available

SPARROW mappers are interactive tools that allow users to evaluate streamflow and nutrient and sediment conditions as well as the importance of different sources of contaminants in a selected river basin. Data can be visualized at different scales using maps and interactive graphs and tables. SPARROW (SPAtially Referenced Regression On Watershed attributes) models estimate the amount …

Assessment of Mercury Bioaccumulation in US National Parks Using Citizen Science

Mercury is a globally distributed pollutant that threatens human and ecosystem health. Even protected areas, such as national parks, are subjected to mercury contamination because it is delivered through atmospheric deposition, often after long-range transport. In aquatic ecosystems, certain environmental conditions can promote microbial processes that convert inorganic mercury to an organic form Source link
