Here's is what I did:
Collect water samples from Farm Lane bridge (500 mL minimum)þ
Filter water samples using small mesh filter
Note: Weigh the dried filter before filtration!
Dry the filter in drying oven (~24 hours)þ
Weigh the filter after drying.
Day Initial Weight Final Weight
4-Apr 0.122 0.12
5-Apr 0.122 0.12
6-Apr 0.12 0.12
11-Apr 0.122 0.121
12-Apr 0.12 0.123
13-Apr 0.12 0.123
18-Apr 0.122 0.123
20-Apr 0.122 0.122
25-Apr 0.122 0.121
Do I measure turbidity using a before and after measurment of my water samples?

No, measuring turbidity requires using a turbidimeter or nephelometer to directly measure the scattering of light by suspended particles in the water sample. It cannot be measured by simply comparing the weight of a filter before and after drying.
