Details

Monitoring combustible or toxic gases in areas with condensing levels of moisture often results in premature sensor failure. Water condensing on sensor surfaces or within the sensor flame arrestor can be difficult to avoid due to widely variable ambient conditions.
 
ATI has developed a solution to this problem with a gas sampling system that also conditions the sample by removing water vapor. The Dri-Gas sampling system draws gas samples from high humidity vent stacks, ducts, wet wells, or other humid locations. The system removes water vapor from the gas sample by contact with a cold plate that condenses moisture and delivers a dehumidified gas sample suitable for toxic and combustible gas monitoring equipment. Excess condensate is pumped to a drain fitting on the bottom of the enclosure and can be collected if necessary.
 
Dri-Gas systems contain a diaphragm sampling pump with brushless DC motor providing operational life in excess of 10,000 hours. The pump is capable of pulling inlet line vacuum of up to 10” Hg. making it suitable for sampling duct system with negative pressures. The outlet of the pump is controlled by an adjustable rotameter allowing system sample flow to be set to the normal rate of 500 cc/min.
 
A differential pressure switch across the pump provides an alarm should the inlet line or outlet lines become blocked. An alarm lamp on the door provides local alarm indication and a SPDT alarm contact is available for remote alarm indication.
 
An optional inlet filter assembly is available for applications where gas streams may contain dust or debris that might cause problems in the air pump. A replaceable filter element on the end of the inlet assembly can be easily changed when necessary. A plugged inlet filter will be indicated by a fault indication. A package of filter elements are supplied with the inlet assembly.

Mining Waste Cleanup Reveals Interesting Lake Dynamics

For the past decade or so, Dr. Bernard Laval , a civil engineer with the University of Northern BC in Canada, has been researching Quesnel Lake , a large, deep lake with unusual water dynamics. This allowed him an unusually high level of insight into much of what makes the lake tick—and when Mount Polley Mine (MPM) experienced a breach in 2014, causing materials to be deposited into Quesnel Lake, he already had a sense of what the lake's waters looked like. “Our work was inspired by a desire to improve holistic understanding of lake function to help with fisheries management by BC Ministry of Environment (BC MOE) and Fisheries and Ocean Canada (DFO),” explains Dr. Laval.

Narragansett Nature: Remote NERR is a leader in salt marsh stressor studies, crab studies and contributions to Rhode Island environmental policies

Unique among the 29 National Estuarine Research Reserves (NERRS), Narragansett Bay National Estuarine Research Reserve (NBNERR ) is made up of four islands: Prudence, Patience, Hope and Dyer. Protecting about 4,400 acres of land and water, NBNERR is a great place to see a variety of coastal habitats. There are upland maritime forests, coastal pine barrens, sandy beaches, cobble shorelines, salt marshes and open grasslands. NBNERR also has excellent hiking, fishing, clamming and bird watching. “If you want to see us, though, you’ll need to hop on a ferry,” says Bob Stankelis , NBNERR Reserve Manager. “Or you’ll have to take a boat. We’re not that easy to get to. But to be honest, that’s one of the big things residents here like about it: its remoteness.

Acid Rain Data Helping Scientists Tackle Water Quality Issues

Since the 1980s, scientists from the Vermont Department of Environmental Conservation (VT DEC) have been sampling water from acid-impaired ponds and lakes and tracking data related to acidity. The line of inquiry began in response to concerns about acid rain, but DEC scientists now find that the long-term monitoring is not only proving the efficacy of the Clean Air Act but also improving local water quality. Guarding the environment in Vermont Rebecca Harvey is a VT DEC scientist, and monitoring the state's waterways for acidity and other problems falls in part to her. Dr. Harvey corresponded with EM about this work.
