Weekly water quality monitoring

Evaluation conducted on Wednesday, September 28, 2022.  We have red flag for the Condado Lagoon Natural Estuarine Reserve. This and another area on the coast did not meet the quality standard, so we recommend avoiding any contact in these areas and being attentive to any precipitation 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.
