Deep Groundwater & Dissolved Gas Sampling With Double Valve Pumps

Download Newsletter Sampling groundwater from deep wells is a challenge on its own, but add to that the need for accurate dissolved gas analysis, and the task gets that much harder. Low Flow, Deep Groundwater Sampling HydroTerra, a leading Australian company, and exclusive distributor of Solinst products, provides environmental monitoring solutions. They have developed a… Continue Reading »

High-Resolution Site Characterization With Multilevel Systems

Within the last few years, the U.S. EPA added a new focus area on high-resolution site characterization (HRSC) to their Contaminated Site Clean-Up Information (CLU-IN) website. The U.S. EPA’s definition of HRSC is: “High-resolution site characterization (HRSC) strategies and techniques use scale-appropriate measurement and sample density to define contaminant distributions, and the physical context in… Continue Reading »

Solinst Bladder Pumps Simplify Groundwater Sampling At Ontario Landfill

An environmental monitoring program is an essential part of any successful landfill operation. Monitoring ensures that a landfill is functioning as it should, and that wastes do not migrate off-site or pose potential risks to nearby receptors. Regular environmental reporting ensures that operators comply with the regulations and approvals that govern them. Landfill Technicians Brad… Continue Reading »

No-Purge Discrete Zone Sampling

No-Purge Discrete Zone Sampling

The Model 425 Discrete Interval Sampler is a no-purge instrument that allows groundwater sampling from specific depths, without mixing of water from different levels. The stainless steel sampler is pressurized before being lowered to prevent water from entering until the desired zone is reached, pressure is released and the sampler fills with water from the discrete zone.

High Resolution Multi-level Monitoring For Bedrock Aquifers

Beth Parker provided attendees with a glimpse of the extensive research she has been spearheading for the past 20 years. Her work is focused on developing the “Discrete Fracture Network (DFN) Field Approach for Investigating Contaminated Sites in Fractured Sedimentary Rock”. Understanding how groundwater flows and chemicals migrate in these networks requires a unique approach… Continue Reading »

Bladder Pumps Exceed Sampling Criteria

A nuclear power facility in England has an extensive groundwater monitoring well network that requires regular sampling. Golder Associates, the project team who developed the network, wished to update their sampling equipment and protocols to improve efficiency, while maintaining accuracy and high safety standards. A set of objectives was defined to help determine the ideal… Continue Reading »
