        7.2.1.      SURFACE WATER WQOS
                    EPP Mary River lowland freshwaters Water Quality Objectives (WQO) to protect aquatic ecosystems are
                    presented below for defined parameters:
                    Table 15 EPP Mary River Lowland Freshwaters WQO’s for defined parameters




                    For toxicants in water and sediment, the EPP Mary River adopts guidance within the Australian and New
                    Zealand guidelines for fresh and marine water quality, October 2000 (AWQG 2000) (Section 3.4 water
                    quality guidelines for toxicants). The management intent (level of protection) ecological trigger values to
                    be applied are for slightly–moderately disturbed systems as noted by the values in grey shading within
                    AWQG 2000 Table 3.4.1.
                    Where required, human health criteria should be adopted from NHMRC, NRMMC (2011 as updated
                    2022) Australian Drinking Water Guidelines Paper 6 National Water Quality Management Strategy,
                    National Health and Medical Research Council, National Resource Management Ministerial Council,
                    Commonwealth of Australia.
                    If required and in the absence of other criteria, the adopted site criteria for surface water shall be the
                    lower of the above ecological or human health criteria for each relevant analyte.

        7.2.2.      GROUNDWATER WQOS
                    The management intent for water quality objectives for groundwater presented in EPP Mary River are to
                    protect the aquatic ecosystem – high ecological value, with the EPP stating:

                    •    Where ground waters interact with surface waters, groundwater quality should not compromise
                         identified Evs and WQOs for those waters.
