<br />Charlie Liu, Ph.D.
<br />Water Quality
<br />PROFESSIONAL SUMMARY
<br />Dr. Charlie Liu is in the Applied Research Group at Kennedy Jenks Consultants with a focus on water quality. He is well versed in
<br />groundwater treatment and has specific expertise in the treatment and analysis of PFAS. He has built, operated, and performed several
<br />pilot -scale demonstrations for both the separation and degradation of PFAS using advanced water treatment technologies including
<br />adsorbents, high-pressure membranes, and UV/sulfite. He is also experienced in water quality challenges associated with water reuse and
<br />the revised lead and copper rule.
<br />CONTRIBUTIONS, INNOVATIONS, AND ACHIEVEMENTS
<br />Dr. Liu has authored and co-authored several publications, including:
<br />• Removal of Per- and Polyfluoroalkyl Substances (PFASs) from Contaminated Groundwater using Granular Activated Carbon: A
<br />Pilot -Scale Study with Breakthrough Modeling. 2019. Liu, C., Werner, D., Bellona, C.
