2018 RPIC Federal Contaminated Sites National Workshop, 13-15 June, Toronto, ON. 21 slides, 2018

In Canada, the Environmental Sciences Group (ESG) partnered with several other groups to conduct a high-resolution site characterization (HSRC) investigation at Sable Island National Park Reserve, a remote and ecologically sensitive barrier island located 175 km offshore of eastern Canada. The unique surficial geology of the assessment location consisted of well-sorted homogenous sand. To realize the use of HRSC technology at the site, a unique low-impact mobile drill rig (LIMB DRIG), was designed and tested through a research grant. The LIMB DRIG was designed to be hand assembled, weigh <150 lbs, fit into a hockey bag, and deliver at least three tonnes of push force. The equipment surpassed all design parameters, allowing for the navigation of site terrain and transport on a small aircraft. The LIMB DRIG was also capable of delivering a laser-induced fluorescence probe for in situ assessment of petroleum hydrocarbons in soil and groundwater using a hand-operated gear drive system in combination with a dynamic hammer. The application of this lightweight delivery system with the HRSC technology in an eco-sensitive and remote site was highly effective, producing a high volume of representative, diverse data in one mobilization.
