matter;
            (c) elevated levels of nutrients, including phosphorous and nitrogen;
            (d) elevated cyanobacteria cell counts or biovolume, toxins and odour compounds;
            (e) water temperature outside natural ranges;
            (f) dissolved oxygen outside natural ranges;
            (g) elevated levels of pesticides, heavy metals and other toxic contaminants;
            (h) pH outside natural ranges;

        Part 3—Water quality objectives for Basin water resources

9.03 Outline of this Part
This Part sets out the following water quality objectives for Basin water resources:
            (a) objectives for:
                (i) declared Ramsar wetlands; and
                (ii) other water‑dependent ecosystems;
            (b) objectives for raw water for treatment for human consumption;
            (c) the objective for irrigation water;
            (d) the objective for recreational water quality;
            (e) the objective of maintaining good levels of water quality;
            (f) the salt export objective.

9.04 Objectives for water‑dependent ecosystems
(1) The water quality objective for declared Ramsar wetlands is that the quality of water is sufficient to maintain the ecological character of those wetlands.
Note: See paragraph 21(3)(c) of the Act.
(2) The water quality objective for water‑dependent ecosystems other than declared Ramsar wetlands is that the quality of water is sufficient:
            (a) to protect and restore the ecosystems; and
            (b) to protect and restore the ecosystem functions of the ecosystems; and
            (c) to ensure that the ecosystems are resilient to climate change and other risks and threats.
Note: See the overall environmental objectives of the environmental watering plan in section 8.04.

9.05 Objectives for raw water for treatment for human consumption
The water quality objectives for raw water for treatment for human consumption are:
            (a) to minimise the risk that the quality of raw water taken for treatment for human consumption results in adverse human health effects; and
            (b) to maintain the palatability rating of water taken for treatment for human consumption at the level of good as set out in the ADWG; and
Note:  See section 1.07 for the meaning of ADWG.
            (c) to minimise the risk that the quality of raw water taken for treatment for human consumption results in the odour of drinking water being offensive to consumers.

9.06 Objective for irrigation water
The water quality objective for irrigation water is that the quality of surface water or groundwater, when used in accordance with the best irrigation and crop management practices and principles of ecologically sustainable development, does not result in crop yield loss or soil degradation.
Note: See section 1.07 for the meaning of soil degradation.

9.07 Objective for recreational water quality
The water quality objective for recreational water quality is to achieve a low risk to human health from water
