The waterproof, battery-operated Thermo Orion Star A321 portable pH meter stands up to the most demanding field applications to deliver the most advanced performance of any portable meter. Four AA batteries, included with purchase of the A321, provide over 800 hours of continuous operation so the instrument is ready when it's needed, where it's needed. The meter displays reliable pH, mV, RmV and temperature readings on a large, backlit LCD screen and automatically locks in stable readings.
Thermo Orion Star A320 series portable meters provide the largest storage capacity available for time-stamped data points, which can be conveniently uploaded to a PC through the meter's USB and RS-232 ports. Automatic or 1 to 5 point manual calibration makes instrument setup simple, while icons provide quick updates on battery life, electrode status and calibration information. The simple button layout and on-screen messages also assist with calibration and explain setup menu choices.

Snowmelt, Stormwater and Contamination in Saskatoon
In Saskatoon, Saskatchewan, pollution and runoff from storms and snowmelt are getting the close look they deserve, and there’s much more to examine. Weather, from heavy spring storms to long months of snow and freezing temperatures, makes the polluting potential of runoff and snowmelt greater than and different from warmer climate cities, said Garry Codling in an email. In Saskatoon, potentially harmful elements in runoff can exceed the guidelines for runoff set by the Canadian government.

Appalachian streams show long, slow recovery from mining’s lingering effects
Appalachia may be as closely associated with mining as it is to anything else. That close relationship will leave its mark on the area’s streams long after the last mine closes. A nine-year study recently published in Science of the Total Environment shows that long after mining activity stops and the land is left to heal, streams and stream life are slow to recover. “We could be really fine point and say that some of them seem to be recovering very, very slowly,” said Carl Zipper, professor emeritus of environmental science at Virginia Tech University . Most of the streams studied didn’t show signs of recovery.

Dissecting the Algae Blooms of Montana’s “Unique Gem” the Smith River
An unusual nuisance is slowly growing into an inexplicable problem for researchers at Montana’s Department of Environmental Quality . For the last five years, a native species of algae called Cladophora has covered large portions of the Smith River, one of the state’s most popular waterways for boating, fishing and recreating. And scientists don’t know why. “It’s just unusual. I don’t know if it’s extreme for the state of Montana as other systems have had Cladophora problems as well. But it’s most unusual due to the lack of land use changes,” said Chace Bell, a water quality assessment specialist with the Montana DEQ.
