Primary Contact Recreation includes protection for when the human health risks to be avoided are through the whole body (immersion), and incidental ingestion exposure pathways. Secondary Contact Recreation (e.g., boating, wading) includes protection for when the human health risks to be avoided are through the limited body contact and incidental ingestion exposure (e.g., splashes, and aerosol) pathways. A “yes” or “no” will indicate whether the NPDES is triggered the Recreational Use flag. The database for which the flag was triggered is noted in parenthesis.
