4. Water quality: other characteristics not for compliance assessment Water quality characteristics that are monitored but do not have a guideline value by the ADWG 2004 and 2011, such as Cryptosporidium, Giardia, and Cyanobacteria (North Richmond only) are reported in this section. These characteristics are not included for compliance assessment and have been agreed between Sydney Water and NSW Health. These characteristics are documented in the Annual Drinking Water Quality Monitoring Plan 2011-12. A summary of any exceptions for these characteristics can be seen in Tables 5, 6, 7, 8 and 9. 4.1 Evaluation of results on exception basis A summary of any exceptions for these characteristics is based on the following definition of an exception for non-compliance characteristics. An exception is considered to have occurred in a sample where: • Cryptosporidium – greater than zero oocysts in any sample volume. The exceptions for Cryptosporidium are reported for both IFA positive and DAPI confirmed positive results. • Giardia – greater than zero cysts in any sample volume. The exceptions for Giardia are reported for both IFA positive and DAPI confirmed positive results. • Cyanobacteria – The notification procedure is a two tiered framework, which includes an initial notification to NSW Health and an alert level for cell counts and biovolumes based on toxin produced by specific cyanobacteria. (see Table 9). The data reported in Tables 5, 6, 7, 8 and 9 are for the quarterly period from 1 April 2012 to 30 June 2012. . Page | 12

The SCA continue to investigate potential sources of Cryptosporidium in the Upper Canal. Also the results of the routine raw and treated water samples are being reviewed in consultation with Sydney Water and NSW Health. The Upper Canal at Prospect is analysed separately in response to either Cryptosporidium and/or Giardia detections in the Prospect raw water composite sample of the same date. Page | 13
