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 »
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.

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 »
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 »
In a town in the Piedmont physiographic province, in the mid Atlantic, a proposed water supply well was contaminated with methyl tert butyl ether (MTBE). The well is located down gradient of several gas service stations with multiple known sources of MTBE. As such, a remedial effort was required by Virginia Department of Environmental Quality… Continue Reading »
Model 464 Easy-to-Use Electronic Pump Control Unit The New Model 464 Pump Control Unit is designed to work with Solinst Pneumatic Pumps to provide high quality groundwater samples. Very easy to operate 125 psi output Pre-set flow rates Saves up to 99 user-created flow rates Uses 4 AA alkaline batteries, that last for 40,000 drive/vent cycles (100… Continue Reading »
Low flow purging and sampling involves extracting groundwater at rates comparable to ambient groundwater flow (typically less than 500 ml/min), so that the drawdown of the water level is minimized, and the mixing of stagnant water with water from the screened intake area in a well is reduced. Solinst Bladder Pumps are able to provide flow rates… Continue Reading »
Solinst provides high quality groundwater instruments that can be used in every phase of a contaminated site clean-up. From the initial site investigation, to further characterization, and finally site remediation, a combination of sampling and monitoring tools are available for each stage of the process. Our Drive-Point Piezometers provide an easy, minimal disturbance approach to the… Continue Reading »
Solinst CMT® Multilevel Systems provide a cost effective solution for identifying and monitoring leaking underground storage tank (LUST) sites. They monitor multiple depth-discrete zones in a single borehole, providing complete data sets that quickly identify sites that pose a threat to down-gradient receptors, and those that can be closed with no further action. With strong political… Continue Reading »
Solinst provides a special “Freeze Protection Assembly” for anyone wishing to dedicate Bladder Pumps in conditions where there is a risk of the sample line freezing. The assembly is simple to install in the field and may be retrofitted with ease to existing Pumps. The assembly can be used with 1.66″ and 1″ Pumps, PVC or… Continue Reading »
