I'm a volunteer scientist for the Grail at their site Grailville and I specialize in water quality work. Most of the work will be monitoring the O'Bannon Creek that runs through their land and dumps into the Little Miami River near Downtown Loveland, Ohio. There is a waste treatment plant upstream near the monitoring test.
Is there contamination coming downstream from the plant?
In order to answer the question, the plan is to test for ammonia, dissovled oxgyen, phosphate, and pH using the colorimetric methods provided by Hach's reagents, as they are already provided to me. I intend to do other experiments down the road.
All methods for the tests can be found on Hach's site.
