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.

As project managers we budget thousands of dollars for drilling and monitoring activities, we send field staff out with forms and field books to fill in, but do we really look at what they bring back to the office and do we have them collecting “valuable” field information. This talk looks at information and data that can be obtained during field activities at a site, this includes what data can or should be collected and how to make use of the data.

Soil Vapour Innovation and Evolution of the Conceptual Site Model – Learning from 20 Years of Data Collectionkeyboard_arrow_down
Data collection, observation and experience has been instrumental in understanding the significance of the vapor intrusion pathway and for informing guidance. This presentation will cover twenty years of data collection that provide insight on data correlations, attenuation factors, importance of fate and transport processes, and site factors.
