H2O Test

I am preparing for the ph test on the Grand River water in Michigan. I have to do the ph test because i chose the new bus choices for our test. The carbon dioxide in the air and water come from vehicles burning gasoline and polluting our air and water. The ph of the water is how acidic the local river is. If the water is less than 5 then it is very acidic. If the water is 5 or above then it is a base. Hopefully our river looks good and the fish are not dieing!
