Invading seawater threatens to pollute or destroy scores of Australia´s coastal water supplies, water scientists have warned. And in many urban areas, thousands of bore owners pump groundwater unabated, leading to potential “tragedy of the commons” situations. In a recent report on the risk of seawater intrusion into coastal aquifers, researchers at the National Centre for Groundwater Research and Training (NCGRT) and Geoscience Australia for the National Water...

A portion of the groundwater in the upper Patapsco aquifer underlying Maryland is over a million years old. A new study suggests that this ancient groundwater, a vital source of freshwater supplies for the region east of Washington, D.C. and Baltimore, was recharged over periods of time much greater than human timescales. "Understanding the average age of groundwater allows scientists to estimate at what rate water is re-entering the aquifer to replace the water we are currently extracting...

University of Miami and US Geological Survey researchers team up to create a model to describe effects of weather and sea level rise on Florida's coastal landscape The key to understanding how future hurricanes and sea level rise may trigger changes to South Florida's native coastal forests lurks below the surface, according to a new model linking coastal forests to groundwater. Just inland from the familiar mangroves that line the coasts lie hardwood hammocks that are sensitive to...

It is a very muddy trek from the small boat to the field site along Raccoon Creek near Bridgeport, N.J. Villanova University marine scientist Nathaniel Weston and his team are all carrying ladders and equipment as they slosh through ankle deep mud toward their experiments. "The whole reason I got into this line of research is because I like being outside, I like coastal estuaries and marsh systems, I like getting muddy, so I have fun with it," says Weston enthusiastically. With support...

By Anonymous WATER ENGINEERING THE SECURITY AND QUALITY of the water supply is a major issue facing every South African community. From tiny dorps to big cities, the demands for potable and industrial or agricultural usage water are ever increasing. Some areas are fortunate to have either or both consistent rainfall and sufficient river and dam capacity, but many municipalities are subject to seasonally distorted rainfall patterns and some face radical demand spikes (for example...

By Anna Ferguson, The Brunswick News, Ga. Jul. 24--The conundrum of a fresh-water supply in Brunswick being contaminated by salt water may soon be resolved. The U.S. Geological Survey recently designed and installed a measurement system using satellite telemetry in a two-square mile area near the city, in an effort to monitor against fresh ground-water contamination. USGS engineers are hopeful that this high-tech equipment will show why the area is being infiltrated with saltwater,...

WASHINGTON, July 9 /PRNewswire/ -- A group representing state environmental regulators across the country today told a congressional panel that current rates of water use are unsustainable and are already leading to critical shortages in some areas. In their presentation to the Congressional Water Caucus, the Ground Water Protection Council (GWPC) called for greater national emphasis and better funding to study and protect underground sources of water. [To view today's report "Ground Water...

By Elaine De Valle, The Miami Herald Dec. 25--Not everyone who lives in Gables by the Sea is technically by the sea. About a quarter of the 360 homeowners in the affluent community do not have access to Biscayne Bay. And just as they have for the past three decades, some of those havenots are trying again to get to the sea. A group of residents west of a saltwater canal dam that keeps them and their boats from the bay have formed the Coral Bay Section Homeowners Association, a...

With the drought elevating a perpetual problem into a critical concern, state water managers are poised today to impose severe new restrictions to combat a seeping front of sea water that threatens the water supply for hundreds of thousands of coastal residents. All residents in Broward and Palm Beach counties would be ordered to slash lawn watering to once a week. Utilities in Hallandale Beach, Dania Beach, Lantana and Lake Worth could face shutting down wells where chloride readings, a red...

By Rotzoll, Kolja; El-Kadi, Aly I; Gingerich, Stephen B ABSTRACT: In recent years the ground-water demand of the population of the island of Maui, Hawaii, has significantly increased. To ensure prudent management of the ground-water resources, an improved understanding of ground-water flow systems is needed. At present, large-scale estimations of aquifer properties are lacking for Maui. Seven analytical methods using constant-rate and variable-rate withdrawals for single wells provide an...
