High-Res Groundwater Monitoring Tracks its Success: Over 40 years ago, a former industrial site in the City of Guelph, Ontario, was contaminated by toluene; the chemical plume has since leached into the underlying fractured bedrock aquifer. Today, the site is home to a unique research project headed by the University of Guelph Morwick G360 Groundwater… Continue Reading »
Spectrasens exclusive distributor of Solinst in the Netherlands, proposed Solinst CMT Multilevel Monitoring Systems to help gather high-resolution groundwater data in the Botlek region. Continue Reading »
HydroTerra, exclusive distributor of Solinst products in Australia, was recently given the task of providing three CMT Multilevel Systems to an alumina refinery in Queensland, Australia. The groundwater monitoring program at the refinery includes monitoring one 7-channel and two 3-channel CMT Systems, and also biannually sampling 90 groundwater monitoring wells located in and around the… Continue Reading »
The answer is yes – especially if you use a Solinst CMT Multilevel Groundwater Monitoring System. CMT Systems are low cost, quickly installed, and are easily customized to suit your multilevel groundwater and soil gas monitoring needs. What is CMT? CMT stands for Continuous Multichannel Tubing. CMT is continuously extruded medium-density polyethylene (MDPE) tubing that… Continue Reading »
GZA GeoEnvironmental (GZA), a multi-disciplinary environmental consulting firm, designed and operates a pump and treat system at a large solid waste landfill in Rhode Island. GZA has been overseeing the system for the past ten years, and have successfully extracted and treated more than 10 million gallons of highly contaminated groundwater. The 230-acre… Continue Reading »
A facility in Pontypool, Wales, UK was once the location of a plastic forming plant. Over time, chemicals produced through the plastic forming processes were lost into the groundwater beneath the facility, creating a large contaminant plume. Years later it was determined that the plume is migrating off site. In order to intercept… Continue Reading »
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 »
SGD is hard to quantify, and site-specific field measurements are critical to accurately estimate rates of SGD. Universities, researchers and associations across North America have been teaming-up to try to understand this process, part of the broader understanding of groundwater-surface water interactions.

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 »
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 »
