Anyone conducting experiments with PFAS may have experienced the frustration of the many practical challenges they pose. 
In this new paper by Thomas James Oudega et al, we share lessons learned and recommendations for avoiding misleading and biased results from porous media column experiments.
Key Takeaways:

• Long-chain PFAS tend to accumulate at the air-water interface, resulting in a non-homogeneous distribution in the water column of the injection solution.
• The injection method, the material and shape of the injection container, the point in the water column to be sampled, and the frequency and interval of sampling must be carefully defined.
• Washing all materials in contact with PFAS with a solvent and measuring the concentration of PFAS in the resulting liquid can be critical to completing the balance of the experiments.
