Decoding the Mysteries of the Gulf Dead Zone
AUSTIN, Texas, October 18, 2007 (ENS) - Off the coast of Louisiana and Texas this summer, an area of deep water covering 7,900 square miles in the Gulf of Mexico was declared hypoxic. This area of low oxygen water called the dead zone was about the size of the state of New Jersey. It is the third largest Gulf of Mexico dead zone on record since measurements began in 1985. The largest dead zone ...

NASA satellite improves pollution monitoring
NASA scientists improved watershed pollution monitoring models by incorporating satellite and ground-based observations of precipitation. The NASA data replaces weather station observations, and will allow states to monitor non-point pollution and improve water quality. The research team, led by Joseph Nigro of Science Systems and Applications, Inc., incorporated two NASA products into a ...

Successfully installed BACTcontrol at the waste water treatment plant in Agon Coutainville
We successfully installed our BACTcontrol at the effluent of the waste water treatment plant in Agon Coutainville, France. Within the H2020 AquaNES project with the support of BRGM the water will be analysed for microbiological and chemical parameters. The Site 9 uses secondary effluent after reed bed and sand dune filtration for golf course sprying in a coastal area. The underlying aquifer is ...

Putting a price on water quality
One way to clean-up water pollution is to award 'credits' to facilities that reduce their emissions. These credits can then be traded with other facilities to compensate for pollution outputs. This controls overall pollutions levels, while creating an economic incentive to reduce emissions. Research using models that simulate water quality has been used to establish the value of these credits and ...

Choking coastal waters
WRI, together with Dr. Bob Diaz at the Virginia Marine Institute, has identified and mapped 415 eutrophic and hypoxic coastal systems worldwide through an extensive literature review. Of these, 169 are documented hypoxic areas, 233 are areas of concern and 13 are systems in recovery. Our findings highlight the dramatic growth of areas receiving the endflows of nitrogen and phosphorus created by ...
