Sulfides can be found naturally in well water and can build up in wastewater collection systems due to anaerobic conditions frequently found there.  In addition, sulfides are used in mercury removal processes and are frequently found in tanning wastes.  In drinking water systems, sulfides cause taste and odor problems.  In wastewater systems, sulfides cause damage to concrete structures in collection systems and contribute to odor problems in treatment facilities.
 
Measurement of dissolved sulfide concentrations has been done primarily by the use of analyzers employing ion selective electrodes (ISE) for sensing. While providing adequate sensitivity, ISE based systems require frequent zero and span adjustments to maintain measurement accuracy.  Because of this, most ISE based monitoring systems are relatively expensive and require frequent service.

Assessing Cumulative Risk From Water Pollutants

New research from scientists at the Environmental Working Group (EWG) shows that an approach that assesses cumulative risk from water contaminants could save lives. EWG senior scientist Tasha Stoiber spoke with EM about how the team developed the innovative new approach . “Our organization has worked extensively on tap water over the years, and an updated version of our tap water database was just released in 2017,” explains Dr. Stoiber. “We've been thinking about new ways to analyze that data.” Right now, the risk from contaminants in water quality is assessed one at a time—but that really doesn't comport with reality.

Custom ROV Helps Protect Rockfish in Puget Sound

Washington Department of Fish and Wildlife (WDFW ) scientists are using a customized underwater robotic vehicle (remotely operated vehicle or ROV) called the Saab Seaeye Falcon on a critical conservation study of threatened and imperiled rockfish. Dr. Dayv Lowry , a Senior Marine Fish Research Scientist, spoke to EM about using the ROV to facilitate rockfish conservation and recovery in the Puget Sound. “In the Pacific Northwest, the Washington and Oregon coast, several species of Rockfish have been fished for decades, with up- and downswings in abundance,” explains Dr. Lowry. “When fishing pressure decreases, and the stocks start to recover, we have gone back to fishing—the pendulum has swung over the years.

Monitoring Wilson Lake All Year Long from Underwater

Since the summer of 2018, Wilson Lake in Maine hosted a data buoy that contains a set of long-term environmental data loggers. The rugged buoy was specially designed for year-round use, monitoring dissolved oxygen and temperature even when it's locked in ice. University of Maine, Farmington biology professor Dr. Rachel Hovel spoke to EM about the Wilson Lake buoy and her team's work with its data. “The ability to generate a long-term data set and collect these data over the entire year is really useful, both in the classroom and for asking questions about what's happening in this lake,” comments Dr. Hovel. Although the Wilson Lake buoy has been deployed for just over a year, these kinds of deployments have the potential to be very long-standing. Dr.
