US ARMY, FORT BUCHANAN is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, serving 6,411 people from surface water.

As of August 1, 2026, its federal record holds 103 entries between 2002 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

All 103 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 synthetic organic chemicals, volatile organic chemicals, and inorganic chemicals.
