The theme of the 2013 Solinst Symposium was “High Resolution, Depth-Discrete Groundwater Monitoring – Benefits and Importance”. A common topic of discussion was the need for high resolution, depth-discrete data sets in order to better characterize and develop conceptual models for contaminated sites. Continue Reading »
Kent’s presentation focused on a small scale (~10 m x 10 m plot) study in which he developed three distinct site conceptual models for a fractured bedrock site, using different depth-discrete hydraulic and tracer transport measurements. 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 »
While completing his Ph.D. at the University of Waterloo, Patryk designed packer testing equipment to be used for conducting hydraulic tests in fractured rock, for contaminant transport studies. 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 »
On November 7, 2013, we held our fourth “Solinst Symposium” here at our facility in Georgetown, Ontario, Canada. The Symposium theme was “High Resolution, Depth-Discrete Groundwater Monitoring – Benefits & Importance”. Continue Reading »
Contaminant mass flux is the measurement of the concentration and flow of contaminants from a source area, represented as mass per unit area per unit time. Contaminant flux measurements show how much, how fast, and where a contaminant is moving – more than you can get from traditional groundwater grab samples. Kirk started his presentation… Continue Reading »
To begin his presentation, Rick discussed the current trends in groundwater remediation. Over the past decade, in situ methods have greatly increased in popularity. Although the use of these approaches is growing, Rick pointed out some limitations. Geological heterogeneity is a limitation to determining hydrogeological aspects of a contaminated site, and how a reagent will… 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 »
