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 »
Gary presented a time-line of key developments in groundwater monitoring technologies, from the introduction of conventional monitoring wells in the 1950’s, to the late 1970’s when the first multilevel groundwater monitoring systems were produced. Continue Reading »
Jessica’s presentation focused on the field work that she has completed at the site. The goal of her research was to use a high-resolution method of measuring head at depth-discrete zones in order to calculate vertical gradients across the site. These vertical gradients were used to delineate hydrogeologic units in the subsurface. Continue Reading »
At the close of the 2013 Solinst Symposium, a round-table was held with the attendees and guest speakers. A common theme in the discussions was education. Continue Reading »
Ryan Wilson used the SABRE project to base his discussion on treatment performance assessment (PA). According to Ryan, PA is about asking questions: Is the treatment working? Why or why not? Is risk reduced? When can treatment stop? Are processes sustainable? Is sufficient mass reduced? What do trends indicate? How can we optimize treatment? How… Continue Reading »
Jim Barker focused his discussion on how contaminants behave in the capillary fringe. The capillary fringe is the zone of soil immediately above the water table. Groundwater is pulled up from the water table by capillary action, filling the pores at the base of the zone. As a result, part of the capillary fringe can… Continue Reading »
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 »
