sec.18 Ambient monitoring

If the chief executive carries out a program of ambient monitoring of waters to assess the state of waters, the chief executive must— carry out the monitoring under— the document called ‘Monitoring and Sampling Manual 2018’, published on the department’s website; and the ‘Australian and New Zealand guidelines for fresh and marine water quality’, published in 2018; and publish the results of the monitoring on the department’s website; and prepare a report about the results of the monitoring. To the extent of any inconsistency between the documents mentioned in subsection (1) (a) , the document mentioned in subsection (1) (a) (i) prevails. If practicable, a comparison of ambient monitoring results with the water quality objectives for, and freshwater flows to, the water during the time of the monitoring must be included in the report. Subsection (5) applies if the measure of an indicator does not comply with a water quality objective because the noncompliance is caused by the natural properties of the water. For preparing the report, the measure of the indicator is taken to comply with the water quality objective if, at the time the indicator is measured, the measure of the indicator is within the natural background level, as determined under the monitoring program, for the indicator. If the results of monitoring show the water quality objectives for the water have not been met, the chief executive may investigate the reasons why the water fails to meet the water quality objectives. In this section— ambient monitoring , of water, includes assessing, analysing, examining, inspecting, measuring or reporting on the following— the quantity, quality and characteristics of water; the effectiveness of control, remedial or rehabilitation measures on the matters mentioned in paragraph (a) . s 18 amd 2020 SL No. 243 s 4 (sec.18-ssec.1) If the chief executive carries out a program of ambient monitoring of waters to assess the state of waters, the chief executive must— carry out the monitoring under— the document called ‘Monitoring and Sampling Manual 2018’, published on the department’s website; and the ‘Australian and New Zealand guidelines for fresh and marine water quality’, published in 2018; and publish the results of the monitoring on the department’s website; and prepare a report about the results of the monitoring.
