6PPDQ Stream Reports

Over the past three years, the project team, in collaboration with dozens of partnered organizations, have collected over 7,000 samples from 85 waterways at 220 locations. All samples were analyzed for 6PPDQ (and several other structurally related PPDQs) representing the largest 6PPDQ dataset globally. Data collected can be found in the interactive database (links above) or a summary of each waterway is provided in the report linked below. The document is organized alphabetically (A – Z) rather than regionally.
