Regulations and End-Use Specifications Explorer (REUSExplorer)
This tool links to summaries of state water reuse regulations or guidelines and is searchable by source of water and end-use application. Results included in this tool were derived from the regulations, guidance, laws, or policy documents of each state and language from the state documents was preserved to the degree possible. These summaries are not legally binding and do not replace or modify any state or federal laws; please always refer to your state for the latest information. You can search the tool for the following reuse end-use applications: potable, onsite non-potable water reuse, centralized non-potable reuse, consumption by livestock, agriculture, landscaping, environmental restoration, industry, and impoundments. This tool was developed by EPA and partners as part of the Water Reuse Action Plan (Action 3.1). Content in the tool is current as of February 2024.
