CALVACHE Water System

Inactive system

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Puerto Rico’s official records. Always confirm current status with Puerto Rico before making decisions based on this information.

CALVACHE is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 676 people from groundwater.

EPA's federal records list this system as inactive in 2013; the record below is historical.

As of August 1, 2026, its federal record holds 105 entries between 1994 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.

Of the 105, 102 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 synthetic organic chemicals.
