SOBRINO is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, formerly serving 3,812 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 13 entries between 1998 and 2001, all of which EPA lists as closed. Nothing has been added since 2001.

Of the 13, 4 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, inorganic chemicals, and synthetic organic chemicals.
