Description:
Environmental health concerns over PFAS and other emerging contaminants are spurring state investment in, and adoption of, non-targeted analysis (NTA) methods. States are using NTA in conjunction with targeted methods to evaluate PFAS occurrence beyond the few dozen chemicals for which targeted methods exist. This is important since the chemical class is known to number in the thousands and broader contamination is suspected. States are motivated to provide a more comprehensive assessment of PFAS to inform public health protection strategies related to source attribution, exposure estimation, risk assessment, and risk management. However, there are significant barriers to state adoption of NTA including instrument cost, analytical expertise, and availability of data processing workflows and tools. Working toward a vision of “making non-targeted the new targeted”, EPA/ORD has been anticipating these barriers and working to develop methods, tools, databases, and data processing workflows to enable NTA adoption. To better assess barriers and evaluate developed tools, EPA/ORD and regional offices (3,5,9) partnered with three states (MD, MN, and CA) leading efforts to deploy NTA to address differing scenarios of environmental health concern. This presentation will provide an overview of lessons learned through this collaboration, state motivation toward NTA, study plans, barriers to implementation, and strategies for overcoming those barriers. Together, this will provide a roadmap and best practices for EPA engagement as other states and regions develop an interest in pursuing NTA.
