This video is meant for educational purposes; it presents simple PFAS fingerprinting scenarios; One involves two rivers and a fire training facility as a potential PFAS source. The goal is to identify the origin of PFAS detected in downstream surface water samples. A second scenario shows groundwater concentrations in monitoring wells, initially suggesting multiple sources.

So why are the pies different? Click here to find out.

For purposes of clarity, these explanation only consider up to 3 PFAS chemicals. In reality, mixtures contain many more PFAS chemicals, but the concepts still hold.
