HRS has particular experience investigating and characterizing the fate and transport of per- and polyfluoroalkyl substances (PFAS) in groundwater at numerous sites.

We have written and implemented PFAS site investigation work plans, PFAS monitoring plans, and standard operating procedures (SOPs) for sampling PFAS in monitoring wells and water wells. We have also created mathematical models that simulate the fate and transport of PFAS in groundwater in alluvial aquifers and fractured bedrock environments.

Colorado’s Authority on PFAS

Dr. Lipson performed basic research on the fate and transport of PFAS in groundwater in a fractured rock aquifer at a fuel depot near Heathrow Airport, and published the results in scientific proceedings. In addition, Dr. Lipson was a principal author of NGWA’s 2017 PFAS best practice document titled “Groundwater and PFAS: State of the Knowledge and Practice.” Dr. Lipson has also given several public presentations on the topic of fate and transport of PFAS in groundwater and most recently gave a presentation on PFAS at the Water Quality Association’s 2018 Annual Convention and Exposition.
