After spending the majority of our time collecting samples and doing water chemistry on site, we are all back in our lab ready to do DNA extractions and PCR galore.

After about an hour of stressing and improvising, we were able to get a usable amount of supernatant…or so we hope. We will find out after we do our PCR.
