Nevada Desert Springs Tandem Filtration 16S rRNA gene reads
16S rRNA gene reads sequenced from filtered water from Nevada Desert Springs, "Cave Spring", "Kiup Spring", and "Grapevine Spring". Filter pore sizes were 1 micron, 0.45 micron and 0.2 micron, arrayed in series so that water flowed through them sequentially. DNA was sequenced from each of the 0.45 micron and 0.2 micron filters.
