H2S Timing Test

[wilsonsj100]

We ran some samples to check how long the sulfide numbers remain constant, let's analyze this and see what we find. We can put it in the H2S folder under protocols or make a new folder called methods testing or tests

@wilsonsj100 I looked at the sulfide data from this timing test. It looks like we only ran 3 samples from July during our September analyses, and one of them ended up above the curve and would have needed to be diluted so it wasn't accurate. Thus, we only have two samples to compare. It does look like the sulfide is higher in these two samples in the September run compared to the July run. I'd be curious how long it takes for the samples to start increasing in sulfide, and I'm also not sure I fully understand why the sulfide would increase and not decrease/turn into sulfate.
