​​​​​​​​​​​​Tasmania is an island State with abundant marine and freshwater resources used by a wide variety of industries and the community, so water quality that is safe and meets environmental requirements is a critical concern of the EPA. The EPA’s aim is to achieve sustainable development and management of water quality by implementing EMPCA and the State Policy on Water Quality Management 1997.

This section provides information on principal water policy and related strategies and guidelines for protecting or enhancing water quality and sustainably managing Tasmania's surface and groundwater resources.​
