SEMIL is one of 449 community water systems in Puerto Rico in the 500 or fewer people size category, formerly serving 404 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 5 entries in 1983, all of which EPA lists as closed. Nothing has been added since 1983.

All 5 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.
