    Estimating the Long-Term Capacity of a Production Wellkeyboard_arrow_down

    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.

    CBN Survey on 15 years of progress on Brownfields since National Round Table on the Environment and Economy’s report on Canadian brownfields (NTREE)keyboard_arrow_down

    The CBN is a knowledge-based national network of passionate, multi-disciplinary industry professionals, focused on uncovering, understanding and sharing brownfield barriers and solutions. The CBN is conducting a national brownfield survey in honour of the 15th year anniversary of the National Round Table on the Environment and Economy’s report on Canadian brownfields. Join Reanne Ridsdale, graduate student from Ryerson University as she explains how to participate and why you should participate. Use your voice to tell us how Canada is doing!

    Phytoremediation of HEPH Contaminated Soils: Land Farm in Northeastern BCkeyboard_arrow_down

    The talk highlights the use of phytoremediation in Northeastern BC to remediate heavier end petroleum hydrocarbons (i.e., more recalcitrant compounds). An overview of site conditions (location, soils), regulatory requirements and client needs will be discussed along with the remedial option selection process. Several different plant species were planted to determine if one or more species was better suited to the contaminants and the climate. One of the projects goals was to use the information gathered from this project to determine if phytoremediation would be an effective remediation technology at similar land farms owned by the client.

    Innovative Investigation Techniques below the Fraser River at a Former Wood Treatment Facilitykeyboard_arrow_down

    This talk will give an overview of innovative investigation techniques that were used in the intertidal and subtidal zones of the Fraser River in support of a monitored natural attenuation remedial option at a former wood treatment facility. In order to characterize the groundwater quality below the Fraser River, multi-level monitoring wells were installed below the high water mark. The groundwater discharge zone was identified and characterized in partnership with a research program at UBC by means of offshore profiling from a boat. Multiple rounds of sampling were conducted to delineate fresh and saline groundwater, helping to establish inferred groundwater flow paths and discharge zones to the Fraser River.

    The Importance & Value of Conducting Detailed Habitat Assessments to Support Ecological Risk Assessments and Remediationkeyboard_arrow_down

    This talk is intended to provide an overview of applicable legislation relating to wildlife, species-at-risk and fish/fish habitat protection and the importance of conducting a thorough evaluation of habitats and habitats supporting fish and wildlife as it relates to information supporting ecological risk assessments and remediation activities. Proper habitat assessments are integral in confirming receptor groups, species interactions, species utilization by resident and seasonal / migratory species, potential impacts and project limitations as well as timing windows and constraints for species occupying sites and surrounding areas.

    The Permeable Reactive Barrierkeyboard_arrow_down

    Since everyone seems to be including PRBs in their remedial options assessments (usually by asking an innocent, guileless contractor to do a free "budgetary" estimate), let's take 20 minutes to review how they work, how you build them, and what drives the costs.
