LOS REYES is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 1,272 people from groundwater.
EPA's federal records list this system as inactive in 2011; the record below is historical.
As of August 1, 2026, its federal record holds 36 entries between 2004 and 2011, all of which EPA lists as closed. Nothing has been added since 2011.
All 36 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 synthetic organic chemicals, the Lead and Copper Rule, and inorganic chemicals.
