MARINI is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, formerly serving 8,308 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 8 entries between 1980 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.

Of the 8, 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, the Lead and Copper Rule, and the Radionuclides and Revised Rad Rule.
