Weekly water quality monitoring

Evaluation conducted Thursday, February 2, 2023. We have a RED flag for the Condado Lagoon Natural Estuarine Reserve. We recommend avoiding the areas that exceeded water quality parameters for enterococci (70 CFU/100 ml). Always remember to avoid direct contact with bodies of water during rainfall events (and at least 48 hours after). 

The actions for the restoration and management of bodies of water within the San Juan Bay Estuary Watershed are possible thanks to the public. Donations to the San Juan Bay Estuary Program are deductible from Puerto Rico and US tax returns.
