Director's Orders 83 is the governing document that describes the Public Health Program expectations of Park Managers. The requirements outlined in DO 83 are in keeping with the requirements as set forth in the Management Policies of the National Park Service, GPRAct requirements and the NPS Strategic Plan(large file).

Reference Manual 83(A1) provides detailed guidance on compliance with the mandates of the Safe Drinking Water Act (SDWA). In addition to the federal mandates under the SWDA, there may be other state and local regulations that may impact drinking water system operation and park liability that should be considered. The National Park Service is committed to being a "good neighbor" within the respective states and compliance with these additional regulation is mandatory.

For further guidance on state and local regulatory requirements, contact your state drinking water representative.
