YAHUECAS is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, formerly serving 3,834 people from surface water.
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 7 entries between 1983 and 1996, all of which EPA lists as closed. Nothing has been added since 1996.
All 7 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 inorganic chemicals.
