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
2013-08-26 14:41:20

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 model sheds further light on the Grotthuss mechanism Protons, as positively charged hydrogen ions, move very rapidly in water from one water molecule to the next, which is why the conductivity of water is relatively high. The principle of proton conduction in water has been known for 200 years and is named the Grotthuss mechanism after its discoverer, Theodor Grotthuss. It is based on the assumption that it is not that a single specific proton moving from one molecule to another;...

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...

A pH meter, typically consisting of a special measuring probe connected to an electronic meter, is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid. The probe measures pH as the hydrogen ion activity that surrounds a thin-walled glass bulb at its tip. A small voltage is produce by the probe that measures and displays pH units by the meter. The meter circuit displays voltmeter in pH units instead of volts. The circuit of the pH meter consists of operational...
