20--eDNA Autosampler

The U.S. Geological Survey is conducting market research for a sources sought effort to identify qualified businesses that can provide an eDNA autosampling platform. The requirement is for an autonomous water sampling system that can collect, filter, and preserve 30 or more eDNA water samples, with supporting metadata logging and design features that reduce contamination risk and simplify field service. The platform must be land-based and deployable from shore, use a UV-based system to minimize biofouling, support various 47-mm filter types and preservation solutions, achieve at least 95% water volume accuracy for samples up to 2 L, operate on a swappable battery pack, and be compact enough for 1-2 people to carry. This is only a sources sought notice and not a request for quote, and responses must be submitted by email to elizabeth_adam@ios.doi.gov no later than Tuesday, May 26, 2026, at 10:00am PD.
