Groundwater Plume Analytics for Assessing Remediation Effectiveness
Joe A. Ricker Bio Abstract

Groundwater Plume Analytics for Assessing Remediation Effectiveness

Remediation effectiveness may be evaluated using a variety of techniques that oftentimes focuses on the performance of engineered remedial systems (e.g., flow rate, energy use, mass recovered, etc.). Rather than focusing on engineered systems, this session will focus on the evaluation of remediation effectiveness by evaluating the groundwater plume dynamics resulting from either anthropogenic or intrinsic remediation systems.
Groundwater plume analytics refers to the use of innovative evaluation techniques and methods to reliably and effectively communication meaningful patterns in environmental data. Analytics relies primarily on graphical displays to communicate insight. Outputs from the Ricker Method® plume stability analysis can be used to further dissect and evaluate dissolved plumes allowing the Ricker Method® to be a powerful tool in plume analytics. Various case studies demonstrating the use of plume analytics tools to evaluate remediation effectiveness will be presented.
Multiple plume analytics tools derived from the Ricker Method® will be presented, with a focus on chlorinated volatile organic compounds (cVOCs) and evaluation of data on a molar basis. This can be important for evaluating and detecting potential new, separate, and/or episodic release sources within a plume.
The Ricker Method® has been successfully used as part of long-term risk management strategies to help stakeholders analyze unique groundwater plume characteristics including area, average concentration, and mass indicator, and describe the behavior of that plume as decreasing, increasing, or stable. Further, the evaluation on a molar basis for chlorinated plumes has been successfully used for the cessation of remediation systems, identification of commingled plumes, identification of potential unrealized source areas, defining specific molar based signatures (biological or abiotic degradation), and providing additional lines of evidence for natural attenuation; examples of which will be presented.

Optimizing In-Situ Bioremediation of Chlorinated Ethenes in BC’s Groundwater

Cleanup of perchloroethene (PCE) and trichloroethene (TCE) in groundwater through enhanced in situ bioremediation (EISB) includes the addition of electron donors (biostimulation) and the addition of beneficial dechlorinating microorganisms (bioaugmentation). EISB is a proven and cost effective remedial approach which is now being widely implemented at Canadian chlorinated solvent sites due to:
• The availability of bioaugmentation cultures and related testing;
• Federal and provincial regulatory approvals for bioaugmentation culture;
• Demonstrated success of bioremediation at Canadian sites; and,
• Novel approaches for amendment distribution in low permeability matrices.
A Canadian bioaugmentation culture (KB-1®) containing Dehalococcoides (Dhc) can be used to enhance bioremediation at sites where these dechlorinating microorganisms are absent or poorly distributed. The KB-1® culture has been available for use in Canada since 2008 upon receiving regulatory approvals obtained through Environment Canada’s New Substances Notification program. As a result, bioaugmentation culture is being applied in Canada including sites in British Columbia. A case study highlighting a successful KB-1® application in the Lower Mainland will be presented.
Geologies where EISB is being implemented include fractured rock as well as low permeability clay and glacial till. Low permeability strata are common in some of the most highly industrialized areas in Canada. Originally conceived as an oil and gas extraction technology, hydraulic fracturing can be used to improve distribution of bioremediation amendments, thereby improving bioremediation outcomes. Electrokinetic (EK) bioremediation is a novel approach that uses an electrical current to move amendments in the subsurface. Examples of successful implementation of hydraulic fracturing and EK-enhanced bioremediation to improve amendment distribution in clay strata will also be presented.

In Situ Stabilization and the Emerging World of In-Situ 3-D Environmental Construction

Stabilisation/solidification (S/S) comprises the amendment of a natural material with reagents, typically cementitious agents, to create higher strength result. It has been used for thousands of years in civil works such as road construction. In the twentieth century, it was extended to applications on contaminated sites, where the mobility and/or bioavailability of contaminants can controlled by, e.g., formation of insoluble compounds, reduction of permeability, control of pore space pH, sorption and micro-encapsulation. S/S has seen extensive application, from the Sydney Tar Ponds, to hundreds of U.S. Superfund sites.
Recent B.C. experience stabilizing tidally-influenced, saturated mixed fill containing rubble, cables and debris demonstrates that new mixing equipment and techniques are effective, even under adverse conditions. The experience also illustrates the potential of 3-D GPS-based machine control with mixing system data acquisition.
The case study includes design, pilot study and full scale in situ S/S data for a shallow (< 3 m) large-scale application in Esquimalt, British Columbia. Redevelopment of the site entailed management of a relatively large area of metals and hydrocarbon contaminated fill. Excavation, transport, and disposal of the 12,000 metric tons of contaminated fill at a licensed waste facility was initially considered; however, the cost was estimated at over $11 million, with significant uncertainty around the management of tidally-influenced seepage into the 4 to 5 metre deep excavation. In situ stabilization solved the problem at less than half the cost. The system reclaimed recyclable/reusable materials and homogenized the residue. Novel depth-specific sample collection equipment was also developed and deployed to provide depth-specific quality assurance sample collection capacity.
Based on the success of the method, a new mixing head was developed which is effective to 8 metres below grade. It is expected machine control advances in the next two to five years will allow the in-situ "printing" of honeycomb containment walls capped with mass-stabilization rafts while maintaining excellent control of both position and mix properties. Such "wall-and-cap" structures can cost-effectively contain contaminated materials while supporting large infrastructure.
