*all times CST, Free to Students and Industry Professionals

The aim of the newly published standard practice for covered geomembrane electrical leak location testing is to locate all leaks in a lining system. Limitations and inadequacies of the previously used covered geomembrane standard practice (ASTM D7007) are all addressed and mitigated by the D8265 procedures. The new standard not only maximizes the sensitivity of the testing methods, but also forces the practitioner to report results in a way that is completely transparent. Therefore, mistakes and uncertainty cannot be hidden. This webinar will cover all aspects of the new standard practice, not only for practitioners, but also for anyone interested in reviewing testing results such as owners, design engineers, and contractors.
You will learn about:
1. How to properly prepare a site for a covered geomembrane survey
2. How ASTM D8265 prescribes the documentation of site conditions
3. Site response current and what this measurement means
4. Voltage mapping for the two different types of site conditions
5. Zero leak documentation
