Part 2: Troubleshooting and Maintenance of Air-Powered Pumping Systems

In this two-part webinar series, David will discuss the criteria used for designing an air-powered pumping system for maximum performance and efficiency and how to maintain these systems for years of reliable operation. Everything from sizing the air system to troubleshooting and cleaning will be covered in these two one-hour webinars. In Part 2, David will discuss the principles of air-powered pump operation and common operational issues, tips on pump installation and removal, cleaning frequency and service life expectations, tools and tips for pump disassembly, and safety considerations during pump maintenance.

Trends in Groundwater Sampling: A Comparison of Groundwater Sampling Methods

Purging and sampling methods and protocols have evolved over the past thirty years, from 3 - 5 well volume purging to low-flow purging and sampling to "no-purge" and passive sampling approaches. This webinar provides an overview of these various groundwater sampling methods and technologies and examines the benefits and limitations of each. A selection matrix provides guidance on the suitability of various purging and sampling methods for differing hydrogeologic settings and monitoring program types.
