“Field School” is designed to address key elements of field methods and protocols for contaminated sites investigations following latest guidance and best practices. The collection of environmental field data is a fundamental and critical aspect of contaminated site investigation, as this data is relied upon to characterize contaminated sites and to provide recommendations for future site management. The methodology used to collect field samples must conform to best practices and regulatory guidance so as to reduce the risk of collecting unusable or invalid data. There are also often multiple methods or ways to collect samples that may depend on project and data objectives and site-specific conditions. There continue to be advances in site investigation and environment data collection, including refinement to sampling methods in best practice and guidance, or ways to optimize or improve the investigation and sampling process. In this course, we bring that information together, in a highly practical and digestible format where we will cover a number of sampling methods, describe how to collect field data and samples while providing examples and tips based on our experiences, describe key quality assurance and quality control metrics, and test knowledge using interactive discussion. The learning process will be enhanced through video demonstrations and step-by-step procedures with class discussion and exercises.
