Testing Omaru Creek turbidity

Testing Omaru Creek for -Turbidity

I am going to find out  about   turbidity of Omaru creek

I am going to test this by Measuring the water from Omaru creek

Resources and equipment The culvert  water make it to the bridge                                                

I predict that the water by the bridge has some rubber in it

I think this because:I think the bridgewater dirty

Results of my tests

Sea Water	9
Tap water	9
Omaru Creek water by culvert	9
Omaru Creek water by bridge	24

My conclusion (what I found out):

The bridgewater is drity

Why I think this is:because there are some rubber
