Water Quality Report.

The primary purpose of this report is to provide citizen scientists and others across Sydney, with locally relevant, expected bandwidths of values for several water quality parameters, rather than a set of triggers as delineated in the more generic ANZECC Guidelines.This report was written using data collected by 32 Streamwatch groups across 63 monitoring sites in the Greater Sydney region. This data was derived from measurements taken between December 1990 and June 2016. In all, 32,125 recorded parameter values were utilised in the analysis.
