When I was reading about you going to the river to take samples of the water I was curious how you do this and what you are looking for when you are taking water samples. Were you looking for any abnormal things in the water samples or anything in perticular? Also, when you take water samples how far apart do you have to go to get a different sample from the river? Does the water in rivers up where you were have a lot of different things than rivers where we are? Also, do you take water samples from the top of the river or closer to the bottom, and does it matter?
