Optimized Approaches Coupled with Interactive Mapping Application Provide a Tool to Visualize the Occurrence of Soil Pathogens

Scientists optimized existing methods to collect and identify microorganisms including Bacillus anthracis, a pathogenic microorganism, in 4,800 soil samples across the United States, and developed a geographic information system (GIS)-based application to visualize microorganism occurrence throughout the United States.

Comparison of Predicted and Measured Pharmaceutical Concentrations in Rivers

New study evaluated if predicted environmental concentrations (PECs) of pharmaceuticals (based on pharmaceutical usage data, degree of metabolism in humans, removal in wastewater treatment plants (WWTPs), and environmental dilution), reflect actual measured environmental concentrations (MECs) in two rivers of different sizes and demographics.

Sources of Contaminants to Congaree National Park—USGS and National Park Service Working Together

A National Park Service (NPS) and U.S. Geological Survey (USGS) study determined the concentrations, potential for degradation, and potential for aquatic and terrestrial animal exposure to organic contaminants in water and sediment within the flood-plain/aquatic environments of Congaree National Park which is located downstream from urban and agricultural areas.

Efficacy of Eggshell Analyses as a Nonlethal Method to Estimate Mercury Exposure in Bird Embryos

U.S. Geological Survey (USGS) scientists evaluated a nonlethal method to estimate mercury in the embryos of 23 bird species using mercury content in eggshells. This method was effective for a wide range of ages and species.

Commonly Used Chemicals Transported to Agricultural Field through Municipal Biosolids Application

Commonly used chemicals (including fragrances, detergents, fire retardants, plasticizers, and antibacterials) transferred to wastewater treatment plants were detected in municipal wastewater biosolids applied to agricultural field plots and subsequently detected in the runoff transported from the plots during precipitation events.
