Water Quality Monitoring
Council regularly monitors the health of five (5) main creek systems within our catchment area. These five sites include:
- Terrys Creek
- Shrimptons Creek
- Porters Creek
- Buffalo Creek
- Archers Creek
Monitoring Water Quality
Water quality is monitored by testing for both biological factors and chemical elements in the water.
Biological factors or biological sampling indicate the number and diversity of aquatic macroinvertebrates (water bugs) present in our creeks. Samples that include aquatic macroinvertebrates sensitive to pollution suggests a healthier creek system.
Chemical monitoring involves measuring characteristics of the water in a creek using a probe (for example, the level of dissolved oxygen and turbidity), and taking water samples back to the laboratory to measure characteristics such as amounts of nitrogen and faecal coliforms in the creek.
Our Bushcare Volunteers have been busy using our new ‘Alert Kit’ to test the water quality in several key catchments: Buffalo Creek, Kittys Creek, Shrimptons Creek, Smalls Creek, Strangers Creek and Terrys Creek. Our Bushcare volunteers are providing useful data and are contributing to our understanding of catchment health. This complements the testing carried out by Sydney Water in spring and autumn and may help to detect pollution incidents.
If you would like to become involved, come along to one of the following Bushcare groups which include Streamwatch during their regular Bushcare activities: Darvall Park, Forsyth Park, Greenwood Park, Minga Reserve, Monash Rd, Kittys Creek and Strangers Creek. We test the dissolved oxygen, temperature, pH, electrical conductivity, phosphate, nitrate, tubidity etc on a monthly basis. For more information about these Bushcare groups, please visit our Bushcare webpage.
