The goal of any environmental sampling program is to answer a specific set of questions. The good news is that environmental sampling approaches and technology have improved significantly over the last 40 years, which has led to increased confidence in the data collected. However, the data is still only as good as the thought and planning that went into its collection. In this webinar, August Mack will provide an overview of tools necessary to develop an effective sampling program, so that decisions regarding a site can be made with confidence. Specific items discussed will include the development of Conceptual Site Models, QA/QC protocols, execution of the field activities, and interpretation of the collected data.
