Session 1: 7Habits of Effective Source Tracking
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous, including detectable amounts typically in the parts per trillion (ppt) range in wastewater effluent and parts per billion (ppb) range in solids. The US EPA plans to publish ambient water quality human-health-based criteria for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) by Fall 2024. The EPA also plans to finalize their risk assessment for PFOA and PFOS in biosolids by Winter 2024.
Tracking down and mitigating these sources would be the first step in proactively minimizing or eliminating these chemicals and complying with upcoming regulatory provisions. Source control would be more cost-effective and environmentally just approach than treatment. This talk will discuss the risks to treatment plants in having to mitigate and comply with PFAS standards and outlines guidance that was developed as part of the Water Research Foundation (WRF) Project #5082: Investigation of Alternative Management Strategies to Prevent PFAS from Entering Drinking Water Supplies and Wastewater to help utilities track PFAS sources.
In this webinar, attendees will learn the following:
Identify appropriate lab methods for PFAS sampling.
Build a PFAS monitoring and source control plan for their wastewater utility.
Session 2: The Next WW Utility Challenge
PFAS is a hot topic in the water and wastewater Industry. Presenters discuss the sources and types of PFAS chemicals, the fate of PFAS during wastewater treatment, occurrence of PFAS in wastewater effluent and biosolids, advanced treatment technologies for PFAS, and current State Water Resources Control Board activities.
Session 3: How PFAS Will Impact Your Pretreatment Plan
Often called “forever chemicals” because of their extreme persistence, PFAS are ubiquitous in the environment and are poorly removed by traditional drinking water and wastewater treatment trains. This presentation will provide an overview of PFAS and their relevance to the water industry. Topics will include why and how PFAS are used, human exposure pathways and environmental concerns, the regulatory landscape, and possibilities for source control.
Learning Objectives:
Name common consumer products in which PFAS may be used.
Explain the history of how PFAS became an important environmental issue.
Understand possible policy solutions to reduce harm from PFAS.
