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 »
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.

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 »
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 »
The 3-Channel CMT® Multilevel Monitoring System is ideal for direct push installations, as it is only 1.1″ (28 mm) in diameter. Often with these installations, the annulus available is too small to accurately place sand and bentonite layers for isolating the monitoring zones. Therefore, bentonite cartridges (spring and pre-formed) have been developed to give reliable seals between… Continue Reading »
