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 »
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 »
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 »
The symposium continued with a presentation by Murray Einarson, with AMEC Geomatrix. His presentation was a great follow-up to Dave Rudolph’s, as it presented methods to obtain the valuable data required, particularly in groundwater assessments. Murray provided an overview of the types and scales of measurements that are important during subsurface assessments and new approaches and technologies… Continue Reading »
