Legacy Of Acid Rain Threatens Eastern US Water Supplies
2013-08-27 06:39:58

Cary Institute of Ecosystem Studies Human activities are changing the water chemistry of many streams and rivers in the Eastern U.S., with consequences for water supplies and aquatic life, so reports a new study in the journal Environmental Science and Technology. In the first survey of its kind, researchers looked at long-term alkalinity trends in 97 streams and rivers from Florida to New Hampshire. Sites ranged from small headwater streams to some of the nation's largest rivers. Over...

Eastern US Water Supplies Affected By Changing River Chemistry

University of Maryland 25+ years of records show two-thirds of region's rivers are now alkaline -- a legacy of acid rain, researchers say Human activities are changing the basic chemistry of many rivers in the Eastern U.S. in ways that have potentially major consequences for urban water supplies and aquatic ecosystems, a University of Maryland-led study has found. In the first survey of its kind, a research team looked at long-term records of alkalinity trends in 97 rivers from...

New CO2 Removal Technique Produces Green Fuel, Offsets Ocean Acidification
2013-05-29 10:31:52

April Flowers for redOrbit.com - Your Universe Online A new technique to remove and store atmospheric carbon dioxide has been demonstrated by scientists at the Lawrence Livermore National Laboratory (LLNL). The new technique also generates carbon-negative hydrogen and produces alkalinity, which can be used to offset ocean acidification. At laboratory scale, the team demonstrated a system that uses the acidity normally produced in saline water electrolysis to accelerate silicate mineral...

How Sensitive US East Coast Regions May Be To Ocean Acidification Revealed By New Study
2013-03-01 12:17:31

Woods Hole Oceanographic Institution A continental-scale chemical survey in the waters of the eastern U.S. and Gulf of Mexico is helping researchers determine how distinct bodies of water will resist changes in acidity. The study, which measures varying levels of carbon dioxide (CO2) and other forms of carbon in the ocean, was conducted by scientists from 11 institutions across the U.S. and was published in the journal Limnology and Oceanography. “Before now, we haven't had a very...

COVINGTON, La., June 13, 2011 /PRNewswire/ -- With everyday expenses and stress on the rise, like gas prices and job pressures, Texans could use a helping hand. Today, Evamor Artesian National Water kicks off an Encounter Goodness movement to help relieve the day-to-day stresses of life. Whether is it the high grocery bill from this week's shopping trip or not being able to find a babysitter for a night out on the town, Evamor wants to pitch in to alleviate the pressure. To obtain relief...

Projects address concern for acidifying marine ecosystems With increasing levels of carbon dioxide accumulating in the atmosphere and moving into marine systems, the world's oceans are becoming more acidic, scientists have shown. To address the growing concern for acidifying marine systems, the National Science Foundation (NSF) has awarded 21 grants under the Ocean Acidification theme of its Climate Research Investment. The awards are supported and managed by NSF's Office of Polar Programs,...

U.S. marine scientists say they have discovered that rising levels of atmospheric carbon dioxide are threatening shellfish populations in many ecosystems. The researchers, led by ecologist Whitman Miller of the Smithsonian Environmental Research Center, said the increasing CO2 levels are contributing to the acidification of open ocean, coastal and estuarine waters. For shellfish and other organisms having calcium carbonate shells and structures, the problem begins when atmospheric CO2...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...
