Studies Look at Scope and Solutions for Litter of Waterbodies

On Oct. 29, the University of California, Los Angeles released a report on marine litter. According to the report, 18 million Mg (20 million tons) of plastic is blown, washed, or dumped into the ocean each year. This trash concentrates in five gyres, propelled by ocean currents. Litter may seem relatively benign, but it is [...]

Reducing Nitrogen in Waterbodies May Take Longer than Previously Thought, Studies Show

Nitrogen has been the subject of several studies over the last month. On Nov. 12, the U.S. Geological Survey (USGS) released a study showing that efforts to reduce nutrient and sediment delivery to the Chesapeake Bay may be delayed due to the slow speeds at which groundwater moves. This particular study focuses on nitrogen from [...]

Model Predicts Regions with Groundwater High in Arsenic

According to a paper recently published in Science, 19.6 million people in China could be at risk from arsenic found in groundwater. Researchers with the Swiss Federal Institute of Aquatic Science and Technology and China Medical University in Shenyang developed a tool that helps to predict areas where groundwater could be high in arsenic. According [...]
