LAS MAREAS is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 516 people from groundwater.

EPA's federal records list this system as inactive in 2012; the record below is historical.

As of August 1, 2026, its federal record holds 13 entries between 1980 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.

Of the 13, 3 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Radionuclides and Revised Rad Rule.
