Final answer:
A No Discharge Zone (NDZ) prohibits the discharge of sewage from boats into the water. It is implemented to protect water quality and prevent pollution.
Step-by-step explanation:
A No Discharge Zone or NDZ refers to an area where the discharge of sewage from boats is illegal.
This means that boaters are not allowed to release untreated or partially treated sewage into the water.
NDZs are implemented to protect water quality and prevent pollution in water bodies such as lakes, rivers, and coastal areas.
For example, in the United States, the Clean Water Act established NDZs in certain waters to reduce pollution and promote clean boating practices.
Boaters in these areas must use onboard holding tanks or pump-out stations to dispose of sewage.
