OLLAS is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 2,095 people from groundwater.
EPA's federal records list this system as inactive in 2015; the record below is historical.
As of August 1, 2026, its federal record holds 12 entries between 1998 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.
Of the 12, 11 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 volatile organic chemicals, inorganic chemicals, and the Total Coliform Rules.
