Overview
The Solinst Model 408 stainless steel double valve pump (DVP) is a pneumatic drive pump that allows consistent, high-quality samples. No bladder replacement is required, and the Double Valve Pump provides higher pumping rates than the Solinst Integra Bladder Pump. There is a selection of sizes and materials, variable flow rates, and it is field serviceable.

Applications
The DVP is suitable for low-flow or regular-flow sampling. The stainless steel pumps can operate to depths of 500 ft (150 m), and the PVC Double-Valve Pump can operate to depths of 100 ft (30 m). Everything is easily accessible, replaceable, and interchangeable. All components can be cleaned with mild detergent or non-phosphate soap. Pumps are not damaged by operation in sediment-laden water or dry pumping conditions.

Mechanics
Flow rates vary with the pump's depth below the surface, the depth below water level, the size of the drive and sample tubing, the drive and vent cycle times, the gas pressure applied, the aquifer recharge, and the size of the pump body.

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.

Monitoring Habitat Suitability and Water Quality in Northwest Arkansas Springs

Northwest Arkansas has seen an economic, industrial, and population boom in recent years as a result of expanding businesses, which have created thousands of jobs in the region and the mass migration of employees and construction companies. However, with this growth has come rapid urbanization and the degradation of the natural landscape, specifically the freshwater springs that can be found throughout the region. These springs are critical habitat centers for native wildlife, home to threatened and endangered fish, and those that have yet to be listed. Zach Moran, Assistant Professor of Fisheries Science at Arkansas Technical University, is working to help monitor these habitats and provide key data that will hopefully inform future development in the region.

Three Decades of Research at Acton Lake

A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.
