EPA Water Technical Assistance (WaterTA) connects communities to experts who help assess and implement solutions for their drinking water, sewage, and stormwater needs. EPA's free water technical assistance initiatives help communities identify their water challenges, develop plans, build capacity, and develop their application materials to access federal funding. The Tackling Emerging Contaminants initiative builds on EPA's robust suite of technical assistance programs and includes diagnostic water quality sampling and analysis, source water assessment, preliminary treatment design and evaluations, operational and sampling training, and identifying solutions to address emerging contaminants and PFAS contamination including community engagement and outreach support.
