Estuario Weekly Update

An estuarine greeting! Through our weekly update, we aim to inform residents and friends of the San Juan Bay estuary watershed communities about events, projects, activities, and training opportunities.

On Tuesday, March 21, 2023, due to an electrical failure at PRASA’s Puerto Nuevo treatment plant, a wastewater overflow occurred in the streets of Condado that affected the Condado Lagoon Natural Estuarine Reserve and surrounding bodies of water. Yesterday, Thursday March 23, 2023, we took samples to perform our weekly bacteriological analysis tests. See the results, below.

We recommend avoiding direct contact with these areas. The next monitoring will be conducted on Monday, March 27, 2023 and the results will be published Tuesday, March 28.
