Water Quality Monitoring Day

The Water Quality Monitoring Day is the biggest civic science event in Puerto Rico.

The Water Quality Monitoring Day is the biggest civic science event in Puerto Rico. It is coordinated by the Estuario de la Bahía de San Juan in collaboration with state and federal agencies, environmental organizations, private organizations, and our volunteer community. This event has been celebrated every year since 2009, with the purpose of motivating citizens to perform simple water quality tests in rivers, lakes, lagoons, estuaries, and the ocean. The goal is to create awareness about the importance of keeping our water in good condition.

E. COLI Bacteriological Monitoring Kit

The CBT (Compartment Test Bag) monitoring kit is a rapid test that does not require special training or equipment to gather data about the fecal bacteria E. coli. While this test cannot be used for regulatory purposes, it will provide a semi-quantitative result and information on the levels of fecal contamination in a surface water sample.
