How to Ensure Safety and Efficiency in Stormwater Sampling
This document discusses key tools and techniques for effective stormwater sampling projects. It emphasizes the importance of planning, preparing properly, and maintaining sample integrity. The presentation covers determining sampling requirements, selecting laboratories, using proper sampling equipment and techniques, managing samples, reviewing results, and documenting the process. The overall goal is to help project managers and field staff successfully plan, execute, and learn from their stormwater sampling efforts.
