Hach's StablCal Turbidity Standard is designed for all turbidimeters and is USEPA accepted for calibration purposes. StablCal Stabilized Formazin Turbidity Standards are true Formazin dilutions developed for use in any turbidimeter. While Formazin primary standards can be prepared directly in the lab, the process is labor intensive and time consuming - and the diluted standards are not stable. StablCal is a stabilized version of Formazin - providing repeatable results, without the time and effort required for lab-prepared standards.

Two autonomous underwater vehicles launch in Lake Ontario

Two autonomous underwater vehicles are drifting through Lake Ontario, monitoring a slew of environmental metrics, according to a release from New York Sea Grant. The high-tech equipment is recording data on fish productivity, food web changes and algae levels. Each AUV weighs 42 pounds, is six and a half feet long and has a slew of sensors, including side scan sonar and 10-beam Doppler. Mapping capability complements collected parameters like temperature, turbidity, pH and levels of oxygen and phosphorus, among others. The research is made possible through the Cooperative Science Monitoring Initiative between the US and Canada called for under the Clean Water Act of 1972.

Sensors to help sort out Storm Lake's sediment issues in Iowa

Wind probably isn’t the first thing that people think of when considering causes of poor water quality, but sediment disturbances caused by the combination of shallow waters and high winds are threatening the health of Iowa’s Storm Lake. Although Storm Lake looks picturesque from a distance, the resuspension of sediment is affecting water clarity and exposing harmful nutrients in the water. Led by Clayton Williams and John Downing, professors in Iowa State University’s Department of Ecology, Evolution and Organismal Biology, a research team has begun monitoring the lake to determine the causes and potential solutions to the lake’s sediment issues.

Clemson studying construction site turbidity

Researchers at Clemson University will help the South Carolina Department of Transportation monitor pollutants discharged from construction sites, according to a release . The state agency wants to make sure it is ready for future federal pollution requirements. Turbidity monitoring near active SCDOT construction sites will judge the effectiveness of the agency’s stormwater runoff protocols. SCDOT will then design enhanced methods to better control runoff from construction sites. Heavy metals, toxic substances and biological pollutants are all associated with runoff from the sites. The study to find better ways to manage the pollutants is funded by a three-year grant from the federal government.
