The Bureau of Reclamation is seeking sources to provide laboratory analysis of phytoplankton in reservoir water-quality samples from the Upper and Lower Colorado Basins. Services include taxonomic identification to the lowest practical level, enumeration, biovolume analysis, QA/QC, and electronic reporting. The work covers both newly collected and backlogged samples using established phytoplankton analytical methods. Reclamation will collect and ship samples to the contractor's laboratory, where the analysis will be performed. No specific timelines or budget amounts were provided.
