System facts

System ID (PWSID): PR0005146
System type: Community Water System
Population served: 820
Service connections: 205
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

QUEBRADA ARENAS is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 820 people from surface water.

EPA's federal records list this system as inactive in 2009; the record below is historical.

As of August 1, 2026, its federal record holds 47 entries between 1980 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.

Of the 47, 22 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 the Total Coliform Rules, the Surface Water Treatment Rules, and inorganic chemicals.
