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.

New federal guidance documents on risk assessments: Amphibians, Birds, and Wildlifekeyboard_arrow_down
The Federal Contaminated Sites Action Plan is publishing 2 new guidance documents: one in support of amphibian ecological risk assessment and the other on default TRVs for mammals and birds. In this talk, Erin Shankie and Elissa Liu from Environment and Climate Change Canada will highlight the intent of these guidance documents and how they can potentially help guide ecological risk assessments.
