System facts

System type: Community Water System
Population served: 856

Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

CEDRO is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 856 people from surface water.

EPA's federal records list this system as inactive in 2010; the record below is historical.

As of August 1, 2026, its federal record holds 31 entries between 1980 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.

Of the 31, 25 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, inorganic chemicals, and the Total Coliform Rules.
