This team used the LaMotte Water Quality Farmland Test Kit for water temp, pH, Dissolved Oxygen, Iron, Nitrates, and Chl orides. This is a new testing site that allows us easy access to the creek. The cre ek at this site takes a 90 degree bend so there are a lot of rocks deposited at the bend for us to walk on during normal flow. Otherwise it would have been extremely muddy. There is a steep b ank but graded steps down the side.
Footing is especially difficult af ter a rain.
The river floods and it has been nearly impossible to safely acquire test data. Th is time, we used a steel calorimeter cylinder from Chemistry class and tied a lot of heavy duty co tton cord to it. We'll mark the cord before next month's testing so we can determine the water l evel from the bridge to the surface and gauge water depth. This technique proved very successful and we look forward to using it again. Dissolved oxygen bottles were submerged in the sample and the water remaining in the bucket was brought back to the school for testing the ne xt day by the general class of 9th grade students.
