## Description

Research aims - Trifluoroacetic acid \(TFA\) is an organofluorine compound\. There is current discussion around its classification as a pesticide metabolite, or a per- and polyfluoroalkyl substance \(PFAS\)\. For the purpose of this research project, TFA will not be classified and will be referenced as an organofluorine compound\. This project will demonstrate the prevalence of TFA in the environment, focussing on risks in drinking water catchments\. Furthermore, the study will provide a comparison between raw and treated water sources to give an indication on the effect of current water treatment processes on the removal or degradation of TFA and the potential risks of exposure to drinking water supplies\.
