CUY N is one of 449 community water systems in Puerto Rico in the 500 or fewer people size category, formerly serving 150 people from groundwater.

EPA's federal records list this system as inactive in 1996; the record below is historical.

As of August 1, 2026, its federal record holds 14 entries between 1992 and 1994, all of which EPA lists as closed. Nothing has been added since 1994.

Of the 14, 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.
