These are the policies, reports, and decisions to anticipate in 2014, organized chronologically, more or less. Great Lakes The government gets […]

Federal Water Tap, December 30: U.S. Geological Survey Data on Pesticides, Groundwater Baselines

Pesticide Use The U.S. Geological Survey updated its maps of pesticide use in the United States to include preliminary data from 2010 and 2011. The use of glyphosate jumped by roughly 13 percent between 2009 and 2011, according to the preliminary data. Glyphosate, an herbicide marketed by Monsanto under the name Roundup, is one of […]

Federal Water Tap, December 16: Climate Change and Water Supplies for Two Western U.S. River Basins

Dropping When It’s Hot The Santa Ana watershed, home to 6 million people in Southern California, faces a number of threats to its water supply because of climate change, according to a comprehensive Bureau of Reclamation study.

A National Research Council report argues that groundwater use today is leaving society poorly prepared for potential rapid climate changes in the future. It is no exaggeration to claim that aquifers, water-saturated layers of subterranean sediment, have allowed agriculture, and thus modern life in our house of 7 billion, to prosper. America’s Great Plains are […]

Federal Water Tap, December 2: Enough Salty Groundwater Beneath South-Central U.S. to Fill Great Lakes Twice, USGS Finds

Lots of Water Aquifers beneath parts of 17 states in the south-central United States hold more than enough salty water to fill the Great Lakes twice, according to a first-of-its-kind U.S. Geological Survey report. Freshwater aquifers in the region, including the famed Ogallala, which irrigates the Great Plains, are well-known, but the last general surveys […]
