The Office of Water (OW) is responsible for implementing the Clean Water Act and Safe Drinking Water Act, and portions of the Coastal Zone Act Reauthorization Amendments Act of 1990, Resource Conservation and Recovery Act, Ocean Dumping Ban Act, Marine Protection, Research and Sanctuaries Act, Shore Protection Act, marine Plastics Pollution Research and Control Act, London Dumping Convention, the International Convention for the Prevention of Pollution from Ships and several other statutes. OW's activities are targeted to prevent pollution wherever possible and to reduce risk for people and ecosystems in the most cost-effective ways possible. The job is much too big to accomplish alone, OW staff depend on many others, including ten EPA Regions, other federal agencies, state and local governments, Indian tribes, the regulated community, organized professional and interest groups, land owners and managers, and the public-at-large. OW often provides guidance, specifies scientific methods and data collection requirements, performs oversight and facilitates communication among those involved.
