The Discrete Interval Sampler can also be used to profile open bodies of water, boreholes, and to collect samples from distinct levels or points of inflow. The Discrete Interval Sampler is a passive sampler that is pressurized when lowered and upon retrieval, to prevent water mixing at different levels. Designed to give zero purge samples.

Solinst groundwater samplers: Versatile options for a variety of applications
Groundwater sampling can be a challenging task that requires different tools for different applications. Solinst groundwater samplers offer the capability to obtain commonly needed representative samples of groundwater using different approaches of water withdrawal. Solinst’s 425 Discrete Interval Sampler uses passive sampling to grab water from a specific depth. The 407 Bladder Pump enables continuous airtight low flow sampling. The 408 Double Valve Pump can continuously sample at variable rates. “One sampler isn’t necessarily going to be for every site,” said Randy Blackburn, Solinst product manager. Each has different means of fluid sampling. The 425 sampler relies on a manual air pump that pressurizes the sampler based on the water depth.

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.
