                            ARMCANZ (2000) for guidance on applying these levels to different ecosystem conditions.
                      B     Investigation levels are taken from the health values of the Australian Drinking Water
                            Guidelines (NHMRC 2011).
                      C     Figure may not protect key species from chronic toxicity, refer to ANZECC & ARMCANZ
                            (2000) for further guidance.
                      D     Chemical for which possible bioaccumulation and secondary poisoning effects should be
                            considered, refer to ANZECC & ARMCANZ (2000) for further guidance.
                      E     For changes in GIL with pH refer to ANZECC & ARMCANZ (2000) for further guidance.
                      H     Values have been calculated using a hardness of 30 mg/L CaCO3 refer to ANZECC &
                            ARMCANZ (2000) for further guidance on recalculating for site-specific hardness.
