A custom automated pathogen sampler and schematic illustration.
A photograph of U.S. Geological Survey (USGS) custom automated pathogen sampler (top) and schematic illustrating the remote-unattended-automated pathogen sampler (bottom). Sample collection proceeds over the course of a runoff-event or low-flow period for up to a maximum of 5 days before a site visit by personnel is needed to collect the samples.

Edge-of-field: runoff before and after conservation practice install
These photos, taken before and after a grassed-waterway conservation practice was installed, show a change in the water clarity of agricultural runoff at an edge-of-field surface monitoring site in Wisconsin.

Edge-of-field: sites and installations
These photos show various edge-of-field monitoring surface and subsurface monitoring sites, installation efforts, and runoff events across the Great Lakes basin.
