The Hach ammonia pocket colorimeter II is a true go-anywhere instrument. It is lightweight, battery operated, and suitable for extended field work or quick, on-the-spot process monitoring. It allows user calibrations, offering the capability for creating user-defined calibration curves or performing a standard adjust.

The instrument comes factory programmed, and no manual calibration is ever required. Simply zero the instrument with a blank, insert the reacted sample, and read the result. The Range Indicator icon on the display indicates either the instrument range or the parameter being tested. Record the ten most recent data points with time stamp - no need to record results manually.

The Pocket Colorimeter II offers accuracy and reproducibility comparable to expensive lab instruments, but is designed for a long working life in harsh conditions. A long-lasting LED is used as the light source, and low power requirements assure long battery life.

300,000-gallon sewage spill has surprisingly minor impacts in Maryland's Mill Creek

On May 28, 2014, an Anne Arundel Community College student stopped on the banks of Mill Creek in Arnold, Maryland, for an ongoing weekly water quality sampling effort there. This week, someone from the county health department was standing on the other bank. "Are you here sampling because of the spill?'" the county worker said, according Sally Hornor, biology professor at the college. "And he says, 'What spill?'" The night before, the Mill Creek Pumping Station lost power and spilled 312,000 gallons of sewage into the headwater of the creek — a tidal tributary to the Magothy River, which flows into Chesapeake Bay.

Study of Texas' Trinity River shows 40 years of improved water quality and fish diversity

Texas' Trinity River is in much better shape than it was a century ago, according to a recent study of decades of fish and water quality data. That's good news for this river, which flows from the Dallas-Fort Worth area to the Gulf of Mexico and supplies the greater Houston area with drinking water along the way. Prior to cleanup initiatives launched in the '70s, it has been degraded "as long as we could tell," according to Joshua Perkin, the study's lead author. "The Texas Department of Health in 1925 described the Trinity River as a 'mythological river of death,'" Perkin said. "And these people work for the health department, so they don't have a sense of humor.

In Sierra Nevada streams, researchers on the lookout for drought-threatened fish

In the parched hills of the Sierra Nevada, researchers are surveying drought-weakened streams to see what effects long-term dryness is having on fish populations in the region. Their findings so far have been less than stellar, with sparse numbers of fish being counted. Still, as data collection is progressing, the researchers, who work out of the University of California, Davis’ Center for Watershed Sciences, are gathering insights that could aid in conservation efforts that are expected to grapple with coming climate changes. The purposes of the investigation are two-fold. “If we ever get rain again, we want to see how well these areas are recovering from drought,” said Rebecca Quinones, a postdoctoral researcher at the center and leader of the project.
