Pictures of detection units for sample #3 (a,b) collected at Pellicer Creek (P1, P2, P3 in for three sample replicates) and sample #4 (c and d) collected at Whitney Lab Docks (W1, W2, W3), and comparison between unfiltered (top row) and filtered (labeled with f, bottom row) samples, along with a positive control (left, in a tube), and a no-template control (right). Pictures in (a) and (c) were taken under room light while pictures in (b) and (d) were taken under a blue LED flashlight with a yellow plastic filter.
