This Webinar is based on CANADIAN experience and law with a focus on British Columbia. The science, however, is universal and the laws and regulations tend to be similar.In BC, if groundwater at a site contains a substance that exceeds the applicable CSR standard, the Site is not a contaminated site if the substance concentration is less than background.Background concentrations for a Site can be established using either:
- Protocol #9 – Determining Background Groundwater Quality, or
- Technical Bulletin #3 – Regional Background Concentrations for Select Inorganic Substances
Global warming and sustainable development are vital issues for our world. Similar to other sectors, an important and emerging question facing the environmental remediation industry is how to integrate the principles of sustainable development. These principles are often summarized in relation to the triple bottom line, which encompass environmental, social and economic factors. This presentation will summarize ways in which sustainability can be incorporated in environmental projects through best management practices and by integrating sustainability indicators into the planning and decision-making processes as laid out in a new Toolkit of Remediation Technologies being developed for Contaminated Sites Approved Professional Society of British Columbia and Shell Global. A roadmap for sustainability evaluations is presented that includes consideration of technical feasibility together with the triple bottom line.

This presentation is devoted to one of the most basic, but also one of the most important, assignments of a hydrogeologist: estimation of the long-term capacity of a production well. Assessing the capacity of a well is not something a hydrogeologist wants to get wrong, but there are plenty of opportunities to do so. The presentation will begin with the distinction between the capacity and the sustainable yield of a production well. The discussion will then move on to a consideration of the two components of the capacity calculation, the allowable drawdown and the specific capacity. Simplified methods of estimating the specific capacity will be reviewed, followed by a more complete examination of the factors that control the drawdown in a well. The role and interpretation of step tests will be highlighted. The presentation will conclude with cautions regarding the extrapolation from short-term tests to predictions of long-term well performance. A set of detailed notes has been prepared to accompany the presentation.
Mr. Neville has over 15 years of experience as a groundwater hydrologist, with particular emphasis on quantitative analysis of groundwater flow and solute transport. He has experience in the synthesis of hydrogeologic data, the evaluation and protection of groundwater resources, and the analysis and design of remedial measures. Mr. Neville has extensive experience in the development of work plans for groundwater projects. He has developed and documented large-scale three-dimensional numerical models for industrial, mining, and government clients, and has reviewed numerous site-specific hydrogeologic analyses and groundwater modeling codes. He is responsible for the testing, documentation, and support of groundwater modeling software at S.S. Papadopulos & Associates, Inc. Mr. Neville has developed and taught professional short courses through S.S. Papadopulos & Associates, Inc. and the International Ground Water Modeling Center. Mr. Neville also assists in teaching graduate courses at the University of Waterloo in groundwater resources evaluation, solute transport, and analytical solutions.

Don’t Forget to Look Up…or Down! Some things to think about when assessing groundwater flowkeyboard_arrow_down
This presentation highlights the importance of assessing vertical groundwater flow in order to properly delineate groundwater contamination, effectively assess the fate and transport of dissolved contaminant plumes, evaluate applicable water use standards, and develop effective remediation plans. A description of characterization requirements and examples will be provided to highlight the importance and benefits of assessing vertical groundwater flow.

An Interactive Training System for Reduction in Cost and Complexity of Remediation and Long-Term Management of Contaminated Siteskeyboard_arrow_down
Site investigation, monitoring and management programs for complex sites are often cumbersome, over- or under-designed, and often contain unknown levels of uncertainty. In addition, the transition from active remediation to long term monitoring is a process of rationalizing and balancing cost, protection of human and ecological health, envelopes of uncertainty, and (often conflicting) stakeholder inputs. This ESTCP project was proposed as a follow-on to the SERDP-funded DIVER project (Data Information Value to Evaluate Remediation – ER-2313) which is developing technical guidance on the value of information for site investigation, remediation and monitoring programs to reduce life cycle costs for complex sites. Building upon DIVER, this ESTCP project developed a web-based interactive training tool for environmental monitoring and performance optimization (TEMPO – Training for Environmental Monitoring Performance Optimization) that incorporates training on the design and review of monitoring systems for performance assessment, site investigation approaches to optimize existing remedial systems, and monitoring programs for long term compliance.
