"Per- and Poly-fluoroalkyl Substances (PFAS) in Nevada - 

Occurrence and Update on Regulatory Framework"

By:  Ben Moan, P.E.,

Supervisor, Nevada Division of Environmental Protection,

Bureau of Corrective Actions


Per- and poly-fluoroalkyl substances (PFAS) are anthropogenic chemicals used in the manufacturing of many common products, including food packaging, water resistant materials, stain resistant materials, firefighting foams, cosmetics, and more. PFAS are very resistant to biochemical breakdown and can accumulate in organic tissue. For these reasons they are sometimes referred to as “forever chemicals.” Evidence to date indicates that specific PFAS can cause adverse health effects, even at relatively low levels, particularly when ingested. Extensive research into the health effects of PFAS exposure and the extent of PFAS contamination in the environment is ongoing nationally, and within Nevada. In 2021, Nevada Assembly Bill (AB) 97 passed, directing NDEP to establish a working group to create a state action plan for assessing risk and exposure to PFAS in Nevada. Simultaneously, the US Environmental Protection Agency (EPA) is working to finalize new rules and guidance regarding PFAS as related to the Safe Drinking Water Act, Clean Air Act, Resource Conservation and Recovery Act (RCRA), and other regulations. The talk will provide an update on recent Nevada PFAS working group activities and discuss the current state of PFAS regulations and state and national roadmaps that outline timeframes for setting drinking water standards and eventual cleanup levels. 


Ben Moan is a supervisor in the Nevada Division of Environmental Protection (NDEP) Bureau of Corrective Actions (BCA) Las Vegas office. BCA oversees remediation of hazardous materials and petroleum hydrocarbons released to soil and groundwater. Most of the releases occur from leaking underground storage tanks (USTs), dry cleaning operations, and vehicle accidents. Ben earned a BS in Geology (2003) and an ME in Environmental Engineering (2014) from Northern Arizona University. Ben worked for 10 years in an environmental analytical chemistry lab before moving to Las Vegas in 2015. He worked at TIMET in Henderson as a process engineer and environmental compliance engineer for two-and-a-half years prior to joining NDEP in 2017. At NDEP, Ben worked as a case officer overseeing approximately 40 remediation cases before becoming a supervisor in December of 2019. Ben is licensed as a Professional Engineer in Nevada.
