Find out about how the City of Stirling is working to combat the issue of declining water quality.Water quality refers to the current health of our rivers, streams and wetlands Australia-wide. Within the City of Stirling there are 37 wetland sites whose water quality is under threat due acid sulphate soils and stormwater drain pollution. May stormwater drains in residential areas carry water from local streets and verges into local wetlands. They thus transport hydrocarbons, pesticides, herbicides, fertilisers and other pollutants that are harmful to those ecosystems, and can impact on the health of aquatic plants, animals and birds. The City is working to combat the issue of declining water quality by installing pollutant traps which catch harmful substances before they enter important wetland systems. We also undertake bi-annual sampling and analysis to monitor changes in the wetlands. You can do your part by minimising your use of herbicides, insecticides and fertilisers around your home, and using environmentally-friendly products.Contact usFor further information please contact City's Environmental Officer Natural Areas via email firstname.lastname@example.org or on (08) 9205 8555.
