So here are the test results for the creek water and well water. Surprisingly the iron levels show the same (.5). Though I dont believe the numbers b/c i can clearly taste and smell the iron in the well water but not at all in the creek water. Yes I did taste the creek water, but then spit it out 
The first image is creek, the second is well
EDIT: Just called the pool store. I dont think I can really trust them or their numbers. They said the sheets my wife came home with were wrong on the iron numbers. They said the creek water has no iron in it, even though the sheet shows it, and they said the well has a little but its not too bad. Funny because I took the well water to a different pool store the other day to have it tested - they used the drops, and the water turned really pink. They said the iron levels were very high which coincided with what my nose and mouth were smelling/tasting. Anyways, this second place said we shouldnt use the creek water, but use the well. Makes me wonder though if they just want us to run into iron issues and come back and buy lots of chemicals.
