What it can and can't tell you
Every result shows the date and time each sample was collected. eDNA and eRNA detect genetic material, not organisms directly. DNA can persist after an organism has left or died, and can arrive from upstream or on boats, birds, or bait. Read counts reflect relative genetic signal, not the number, size, or biomass of organisms. Species names depend on reference-library coverage; some detections resolve only to genus or family. A detection is evidence to follow up, not confirmation that a population is established, and a non-detection does not prove absence. These are not EPA-approved methods and are not a regulatory determination. Results can help you make decisions about safe swimming and water use, but no result is definitive for every place and time. It is always good practice to check posted signs and your state or local health authorities.
