Groundwater Recharge

February 16, 2014--14 reservoirs in Southern California near record lows (San Gabriel Valley Tribune)

Less than 1 percent of the capacity of the 14 dams spread across Los Angeles County is available for release, according to data from the Department of Public Works. Of the 183,000 acre-feet possible, the county has about 759 acre-feet it can release to replenish sinking aquifers -- a 22-year low.


January 19, 2014--Arizona is overdue to discuss its No. 1 problem: water (Arizona Daily Star)

Here’s why water must be Arizona’s top public-policy debate: Back in 1980, the Legislature finally responded to the rapid drop in groundwater levels caused by population growth and farming. It set a goal for the Phoenix, Tucson and Prescott areas to balance our groundwater withdrawals with natural and artificial recharge by 2025.


November 12, 2012--Water supply in a warming world (New York Times)

More than anything else, climate change is a water problem. Scientists expect more coastal flooding and possibly more inland flooding. They expect higher temperatures and greater evaporation to deplete water resources, creating risks for the food supply. They believe sea-level rise will eventually render some regions uninhabitable.


October 23, 2011--Evaporating water supplies (Washington Post)

As the global population reaches 7 billion, ecological distortions are becoming widespread. Among the changes are a drop in fresh water supply in more than two dozen of the largest African nations and a net loss of forest in South America and Australia. Nations with stable or declining populations, such as the United States, have seen a rise in acreage and density of temperate forests.


October 15, 2009--California passes bill to encourage stormwater reuse (Los Angeles Times)

During the wet season, the city of L.A. sends 100 million gallons of stormwater into the Pacific each day. That water had, for many years, been handled as pollution, since the water produced in rainstorms picks up various effluents that then flush into the ocean.


April 17, 2008--Planet-friendly paving lets water seep through (Washington Post)

Paved sidewalks and driveways keep shoes clean and cars out of the mud. But environmentally speaking, too much paving is a disaster, blanketing the ground and preventing rainwater from soaking in. Runoff, especially after strong storms, erodes soil and carries oily residue into streams and eventually into sensitive estuaries. Pervious paving, though, is friendlier.
