This webinar is a must to prepare for upcoming PFAS testing of biosolids; how to respond to regulators and the public when they have questions. Understanding and interpreting PFAS analytical lab reports is confusing. The webinar will explain PFAS chemistry, how to interpret qualifiers (flags), reporting limits, and how to address compliance and reporting. 

This webinar is geared toward management, laboratory staff, and consulting engineers.

Presentation Title: Interpreting & reporting PFAS results – A Utility perspective
 
Presentation Summary: PFAS lab reports can be confusing and complex. The need for accurate interpretation and reporting is amplified by public perception of PFAS risk and potential consequences of noncompliance with regulatory limits. This presentation will provide a Utilities perspective of lessons learned and highlight several key factors for consideration when reporting.
