CRC CARE is a world leader in research into per- and poly-fluoroalkyl substances (PFAS). Our work has built a strong knowledge base of methods for analysing and remediating PFAS, as well as potential health impacts on the environement, animals and people. We have also registered and applied for a number of patents for methods and technologies for PFAS assessment and remediation.
