Florida City to inject treated sewage directly into underground aquifer
Florida’s Biscayne Aquifer has begun to run low and communities are exploring alternative sources of water as well as methods to stretch existing sources; the city of Pembroke Pines plans to inject treated sewage water 60 to 200 feet below ground directly into underground aquifers rather than use the existing practice of pumping treated water into nearby wetlands, lakes, or fields, where it will slowly trickle down into the aquifer over several months or years

Wastewater treatment lowers pathogen levels
New analysis shows that pathogens levels in municipal water have dropped since the implementation of federal regulations on treating sewage in 1993; these treatment guidelines have proven to be extremely effective with 94 percent to 99 percent of all pathogens in biosolids eliminated after wastewater treatment

China to step up efforts to control Mother Nature
China is facing increasingly sever water shortages; the Chinese government is expanding it activities to combat extreme weather such as droughts, exploring airborne water resources, bringing water from he sea inland, and other measures to secure stable water supplies for cities, industry and agriculture

Seaweed: the new trend in water purification
UConn biologist Charles Yarish is turning his enthusiasm for seaweed into a new system for cleaning up waterways; Yarish’s most recent endeavor will use seaweeds to clean up pollution from human sources, as well as waste from fish and even people; this approach, dubbed extractive aquaculture or bioextraction, promises to use the physiological properties of seaweeds and other organisms to clean up excess nutrients in polluted areas, making them healthier, more productive, and more economically viable

Freshwater sustainability challenges shared by Southwest and Southeast
Twenty-five years ago, environmentalist Marc Reisner published Cadillac Desert: The American West and Its Disappearing Water, which predicted that water resources in the West would be unable to support the growing demand of cities, agriculture, new research offers new support for most of Reisner’s conclusions, using data and methods unavailable to him in 1986

Desalinating water, producing hydrogen, treating wastewater -- simultaneously
Fresh water and reusable energy: humans are on a constant hunt for a sustainable supply of both; trouble is, water purification requires a lot of energy, while utility companies need large amounts of water for energy production; researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an answer

Haiti's escalating crises come down to lack of clean water
Haiti’s corrupt and indifferent government has done little to improve water and sanitation since a 12 January earthquake, making it likely that the cholera epidemic there will continue to spread; even before the quake, more than a third of Haitians lacked access to clean water; now, more than two-thirds of Haitians have no access to clean water; less than one-fifth of the population has access to a simple latrine or toilet

Nature's desalination: bacteria turn salty water fresh
The growing global shortage of water has led to a growing interest in desalination to produce fresh water from seas and estuaries; conventional desalination plants, however, consume large amounts of energy; the solution: a bug-powered desalination cell that takes salt out of seawater

One in five global businesses affected by growing water shortages
Experts say that by 2030 global water demand would outstrip supply by 40 percent; a new survey reveals that we do not have to wait that long: drought, shortages, flooding, and rising prices are already damaging companies in water-intensive industries

China to push sea water thousands of miles inland
Chinese officials say they have a found a solution to uninhabitable deserts of Xinjiang in west china: pump raw sea water thousands of miles from the coast to fill Xinjiang’s dried-up salt lakes and desert basins in the hope that it will evaporate and encourage rainfall over drought-stricken areas of northern and northwestern China; the sea water would be carried through a pipeline made of plastic and fiberglass; water experts have condemned the proposal

Crumbling water infrastructure needs investment boost
Water pipes and treatment systems in the United States are in a sorry state, but nearly two-thirds of voters and just over half of businesses would be willing to pay more for their water to ensure its quality and availability; the U.S. Environmental Protection Agency said that at the current rate of investment, the funding gap for water infrastructure could grow to as much as $224 billion by 2022

Large parts of the world are drying up
The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa, and South America, have been drying up in the past decade as a result of intensified “evapotranspiration” — the movement of water from the land to the atmosphere

Worldwide groundwater depletion rate accelerating
In recent decades, the rate at which humans worldwide are pumping dry the vast underground stores of water that billions depend on has more than doubled; if water was siphoned from the Great Lakes as rapidly as water is pumped out of underground reservoirs, the Great Lakes would go bone-dry in around 80 years

Coal waste has contaminated water in 34 states
Coal-waste disposal sites have contaminated drinking and surface water in 34 states; the sites released pollutants such as arsenic, selenium, lead and chromium into water sources on which both humans and farm animals depend; there could be a bigger problem yet: large coal ash-generating states like Alabama, Arizona, Georgia, Indiana, Ohio, Mississippi, Missouri, New Mexico, and Tennessee, require no monitoring by law at coal ash ponds, so the pollution of water by coal ash is not even monitored

California drought highlights the state’s economic divide
As much of Southern California enters into the spring and warmer temperatures, the effects of California’s historic drought begin to manifest themselves in the daily lives of residents, highlighting the economic inequality in the ways people cope. Following Governor Jerry Brown’s (D) unprecedented water rationing regulations,wealthier Californians weigh on which day of the week no longer to water their grass, while those less fortunate are now choosing which days they skip a bath.
Changing human behavior key to tackling California drought: Expert
California is experiencing a drought that has gone far beyond a “dry spell,” and the state has imposed the first water restriction in state history, aiming to cut back on water consumption by 25 percent. One expert says that strict water conservation measures are long overdue, and that “what is happening is a realization that you can’t simply transplant another ecosystem onto a California desert system or arid southwestern system. In a sense, California and much of the U.S. southwest are living beyond their ecological means. Certain lifestyles have been adopted and crops are being grown that are not endemic or sustainable for this particular bioregion.” He adds: “This is a moment for not just cutting off personal water use and turning the tap off when you’re brushing your teeth, as important as that is. This is a moment of reflection, invitation and, I hope, legislation that will cause people to think about water use in the industrial sector too. This is for the long-term prosperity of the state and sustainability of the ecosystem.”
