Evidence of pollution:

Sample 1:

After collecting this sample i examined the pollution as the water was clear, but the water in the harbor was polluted in terms of rubbish lying in the water, this shows that there is minimal pollution.

Sample 2:

sample 2 was polluted as when i went down to collect the water i had to be careful because there was broken glass that looked like broken beer bottles. There was a lot of glass lying around on the sound i would say the sand was 25% glass. There was a few pieces of rubbish in the harbor.

Sample 3:


I took this sample from the main pond in the botanicals gardens it was very polluted as released the gas called rotten egg gas and my bottle contained floating particles of algae and other particles due to plant life in the pond. The bottle was a medium green colour which shows high levels of pollution.

Sample 4:

This was the most polluted out of all the samples areas due to the strong odor called rotten egg gas as it was the stronger than the last one. There also was more particles floating around like dirt and algae in the bottle. After taking the sample the bottle was green and look like lime cordial. The bottle was stained after releasing the water.
