The marine water quality in Port Phillip Bay is generally good and meets most of the State Environment Protection Policy objectives on most occasions. A summary of the recent water quality monitoring for some important parameters is shown in the table below.
Whilst the water quality is generally good, water samples sometimes fail SEPP objectives for turbidity (secci disc depth), chlorophyll and dissolved oxygen. Turbidity is an important parameter to monitor because high turbidity reduces light penetration and hampers the ability of seagrass and mangrove communities to flourish.
This assessment of the condition of marine water quality is used as the basis for setting targets for the future (Targets). Lead organisations are committed to achieving the targets (Leadership) and arrangements are in place to monitor and report on progress and success (Monitoring & Reporting).
