Testing Nitrates

On Tuesday, we tested the nitrate level in the stream. We tested in two spots, 1 spot right near the riffle and 1 spot right by one of the run off tubes coming from one of the houses. In both spots, the level of nitrates was approximately 13.6. 13.6 is a good number because we dont want too many nitrates in the water, but at the same time, we don't want very low levels.
