Weekly water quality monitoring

Evaluation carried out on Thursday, March 30, 2023. We have a RED flag for the Condado Lagoon Natural Estuarine Reserve. The map identifies the stations that exceeded the water quality parameter for enterococci (70 CFU/100mL). We recommend avoiding direct contact with these bodies of water during rain events.

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.
