Data Center Description
The Office of Science and Technology (OST) is one of five water offices at EPA. We set national environmental baselines for the quality of the Nation's waters. We help ensure the latest water pollution science and best available control technologies to support Office of Water program goals to keep water safe and clean.
Every year under the Clean Water Act and Safe Drinking Water Act, OST produces regulations, guidelines, methods, standards, science-based criteria, and studies that are critical components of national programs that protect people and the aquatic environment.
