Cronulla Beach- Waste Management- Rebecca O'Farrell
The aim of this fieldwork is to observe how pollution occurs and affects Cronulla Beach.
Questions:
1. What species of animals are affected by the rubbish pollution at Cronulla?'
2. When was rubbish pollution at Cronulla first a big issue?
3. What is the main issue caused by pollution at Cronulla?
4. What causes the rubbish pollution at Cronulla Beach?

This is a record of all the different areas visited while doing the field work at Cronulla:
1.Humans a greatly affected by bacterial pollution.

But all organisms are vulnerable to human pollution.
Fish are sensitive to high levels of sediment in water and they find it hard to hunt for food when the water is murky. High levels of metal are associated with sediments.
Sea grasses are also vulnerable to high levels of sediment and the nutrient in water as photosynthesis can be reduced and nutrients increased, algal blooms can be the result of this.
Turtles are also affected badly. Floating plastic bags or other rubbish could be mistaken for food.
Bethnic organisms are affected by boats and sewage treatment plants and desalination plants.
2. Rubbish pollution has always been a big issue at Cronulla. Many items wash up on the beach but the most common items would be cigarette butts, plastic water bottles and other drinks.

3. Cronulla's beaches are low in bacteria compared to other Sydney Beaches. The Boat Harbour at Cronulla has an onsite sewage treatment system which contributes greatly to the bacteria in Cronulla.

The councils monitor water quality from the storm water drain. Results are at this link:

The causes of pollution at Cronulla Beach are:
Rubbish not being disposed of in bins
Illegal dumping
Overflowing of bins
Dumping of rubbish from boats including sewage
Using storm water drains as disposal systems
BEACHWATCH
Beachwatch started in 1989 in response to a public concern over the rising level of pollution at Sydney's beaches. At that time, more than 1 billion liters of sewage was put into Sydney's waters each day and visual indicators of the pollution like sewage grease and condom rings were regularly washed onto beach shores.
Water quality at Sydney's beaches today, is 98% cleaner. Deep ocean outfalls were put in place and service to Sydney's main coastal sewage treatment plants was put into place by Beach Watch. The impacts of storm water pollution and sewage overflows means that poor water quality can still be measure after rainfall.
