Invertebrate sampling - sieving
After collection, invertebrates are washed through a series of sieves where large debris can be removed before being placed in the sample bottle.

Invertebrate sampling closeup
Close up-view of defined area of the stream bottom where attached invertebrates are removed with a brush and washed into the Surber net; where possible, a hand rake is also used to dislodge organisms from shallow depths.

Algal sampling after removal of subsample
Close-up view of defined area of a rock cobble (middle) where attached algae and other material were removed with a brush. Rocks from multiple locations at a site are composited into a single sample representing the stream site.

Invertebrate sampling
USGS scientist collecting one of five subsamples of aquatic invertebrates from a stream riffle by removing invertebrates from a defined area and collecting them with a Surber net. Each subsample is transferred to a bucket for compositing into a single sample for the site.

Ultrafilters and bottles
Ultrafilters are used to concentrate pathogens from large-volume surface water samples. Plastic autoclaved bottles used for human-associated indicator bacteria analysis. Glass bottle used for DOC, simultaneous fluorescence and absorbance, and pharmaceutical compound analysis.
