The International Atomic Energy Agency (IAEA), in collaboration with the University of Massachusetts, has developed an innovative method for tracing the origin of nitrogen … [more…]
Public water systems serving more than 5.6 million Americans contain concentrations of nitrate at levels found to cause health problems, including cancer and birth defects, according to a new study published in the journal Environmental Health. Systems serving Hispanic populations tended to have the highest levels of nitrate in drinking water.
Nitrate in water originates from various sources, including fertilizers, sewage treatment systems, and … [more…]
Study shows complex connection between meltwater discharge and nutrient input — ScienceDaily
Summary: The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which … [more…]
In one of the first studies to examine the potential for using municipal wastewater as a feedstock for algae-based biofuels, Rice University scientists found they could easily grow high-value strains of oil-rich algae while simultaneously removing more than 90 percent of nitrates and more than 50 percent of phosphorus from wastewater.
The findings, which are based on a five-month study at a wastewater treatment facility in Houston, are available online … [more…]
The vast majority of Californians are fortunate enough to take access to clean drinking water for granted. However, the fact that some Californians in small, rural communities do not have this access is a travesty in this modern day and age. It can and must be fixed as an urgent state priority.
Resolving this unacceptable situation will come at … [more…]
