Does your state have published limits for PFAS? If so, what are they for drinking water? Groundwater? Surface water? Soil? Which PFAS do you have standards for? PFOA/PFOS only? Others? Are you considering regulating additional PFAS in the future. If so, which ones? If not, what limits would you use and why? If you have limits, what are they based on? What is the toxicological endpoint? What study was used and why? If noncancer, what is the hazard index used in your state (e.g. 1 or 0.1)? If cancer, what is the risk level used in your state (e.g. 10-5 or 10-6 )? What is the assumed duration of exposure? Other factors? Is your state considering changes and if so, what’s likely? 12:15 Lunch (provided)
