PFAS Symposium

ESAA PFAS Symposium

calgary fairmont 2
7:15 am to 5:00 pm
December 6th, 2023

Fairmont Palliser, Calgary



Event Sponsored by:

ALS NEW 2022

PFAS, PFOS and other forever chemicals are widely used, long lasting chemicals, components of which break down very slowly over time.  These chemicals are now everywhere in the environment (soil, water and blood streams of people and animals).  Remediation and management of PFAS-contaminated sites are very challenging and complex, and the removal of PFAS from the broader environment is not currently possible.

This one day symposium will feature 5 panel discussions each focussing on a different aspect of this growing issue: Science,  Legal, Testing, Risk Management and Treatment.
