1. fishery
2. rocks pools
3. south darook
4. cliffs

SOIL
my soil was all quiet similar, it was brown in colour and quiet fine, moist and smelt like normal dirt. although the soil samples i gathered from the fisherys (#1) and darook cliffs (#4) were more sand based rather than pure soil.

SOIL PH - AVERAGE

1. 5.88
2. 6.38
3. 6.6
4. 6.68
WATER
TURBIDITY
darook beachs water is very clear and persumably clean, which resulted in my turbitity tests being 0. the tube filled all the way to the top and i could still see the lines at the bottom of the tube.

WATER
PH
1. 5. 2 - 8.34 - 7.02
2. 5. 34 - 8.45 - 6.57
3. 6.33 - 7.73 - 6.45
4. 5.45 - 7.9 - 6.62

WATER - when i looked at my water to search for visible signs of pollution, i saw no evidence of rubbish, only abit of sand.
Phosphate
1. 0 - 10 - 5
2. 0 - 25 - 0
3. 0 - 25 - 15
4. 0 - 25 - 5

before it rained i gathered my samples. all my results were 0 for phosphate, it had not rained in over a week, impliying there was no fertilizers/pollutents in the water.
after rain phosphate levels were fairly high for different areas. where there was more grass phosphate levels were higher from fertilizers.
a few days after rain the water was getting back to a more neutral level.
