SALTILLO is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 770 people from groundwater.

EPA's federal records list this system as inactive in 2010; the record below is historical.

As of August 1, 2026, its federal record holds 10 entries between 1983 and 1999, all of which EPA lists as closed. Nothing has been added since 1999.

Of the 10, 9 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 and the Total Coliform Rules.
