1 Forward This is a data report to summarise the receiving water quality of Sydney’s Inland and Coastal Waterways. The data upstream and downstream of Sydney Water’s Inland Sewage Treatment Plants (STPs) are presented to satisfy Condition M10 of Sydney Water's Environmental Protection Licences. Sydney’s coastal waterways data are also presented to describe general ambient conditions. The report presents the summary of last year’s data (July 2006 to June 2007) in dry weather and wet weather categories. It also included last ten years trend plots for key water quality indices.
The data set used in this report is collected by the Performance Assessment Monitoring Program (PAM). This program is comprised of a number of discrete components, one of which involves sampling upstream and downstream of Sydney Water STPs to assess STP impact on receiving waters. The water quality component of the program involves monthly routine sampling of sites throughout Sydney’s waterways (Hawkesbury-Nepean and tributaries, Port Jackson, Georges River, Cooks River, Port Hacking and Coastal Lagoons) and 3 wet-weather sampling events where rainfall across the catchment exceeds 25mm in a 24 hours period. This report separates dry and wet weather samples based on rainfall data, and provides information on receiving water quality.

2 Approach and Methodology
2.1 Sampling Sites and Method All water quality sampling sites for various waterways are listed in Table 1 and Table 2. The location of all sampling sites are shown in Figure 1 to Figure 6. All sampling (regular monthly and wet weather response sampling) comprised collecting replicates from each site. Water samples were collected from 0.5m depth where depth of the waterway was sufficient. Field measurements were taken and samples were analysed for the selected water quality variables listed in Table 4.
2.2 Data Analysis The data for the period between July 2006 and June 2007 was used for analysis. Receiving water quality data were separated into dry and wet weather category using catchment weighted rainfalls. Water quality at all these locations is affected by wet weather, either due to runoff from the catchment or input of pollutants from sewer overflows. Wet weather was defined as a day when greater than 15mm of rain had fallen in the previous 72 hours. All other days were dry weather. Relevant rainfall stations used for each site and different section of the river and catchment are shown in Table 3. List of abbreviations used in summary statistics tables are shown in Table 4 and Table 5.
In summary statistics tables, means are geometric means for faecal coliform and enterococci data. In yearly trend plots, the range of data for a year was plotted and the mean of each year connected with a line to show year-to-year changes in the mean. For temperature, the data was plotted as a time series to show seasonal patterns. This data was not separated into wet and dry weather.
