GUAYANES I is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 2,006 people from groundwater.

EPA's federal records list this system as inactive in 2015; the record below is historical.

As of August 1, 2026, its federal record holds 18 entries between 1980 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.

Of the 18, 10 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 Lead and Copper Rule, and synthetic organic chemicals.
