Citizen Water Quality Testing

Thank you for your interest in the Citizens Water Quality Testing (CWQT) Program. This Harbor-wide initiative, managed by Billion Oyster Project, engages community scientists in weekly testing of New York Harbor water for bacteria that can be harmful to humans. 

This program, initially organized by the New York City Water Trail Association, aims to increase equitable access to our local waterfront by consistently reporting on the health of New York Harbor and advocating for a change to New York City’s antiquated combined sewer system. This work is made possible with support from Two Trees Management.
