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.

System facts

System ID (PWSID): PR0004064
System type: Community Water System
Population served: 15,937
Service connections: 5,136
Ownership: local government
Water source: groundwater (wells)

LOS CANOS is one of 61 community water systems in Puerto Rico in the 10,001 to 100,000 people size category, formerly serving 15,937 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 62 entries between 1994 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.

Of the 62, 58 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 the Total Coliform Rules.
