Nutrients in Dust from the Sahara Desert cause Microbial Blooms on the East Coast of the United States
Saharan dust nutrients, particularly iron, deposited episodically in tropical marine waters stimulate marine microbial bloom growth and change microbial community structure.
Bacterial Pathogen Genes in Streams related to Animal Type and Hydrologic Conditions
A U.S. Geological Survey (USGS) study elucidates the influence of animal type and environmental variables on bacterial pathogen occurrence in streams under typical watershed conditions.
Importance of Lake Sediments in Removal of Cyanobacteria, Viruses, and Dissolved Organic Carbon
U.S. Geological Survey (USGS) scientists determined that the colmation layer (top 25 centimeters of lake sediments) was highly effective in removing cyanobacteria, viruses, and dissolved organic carbon during water passage through the lake bottom to aquifer sediments.
Potential Exposure to Bacteria and Viruses Weeks after Swine Manure Spill
Manure spills may be an underappreciated pathway for livestock-derived contaminants to enter streams. Scientists from the U.S. Geological Survey (USGS) and Johns Hopkins Bloomberg School of Public Health studied an Iowa stream after the release of a large volume of swine manure (a manure spill). The scientists observed an increase in viruses and bacteria, which have the potential to cause human or...
