Where the water comes from

Mamey draws water from 1 well.

Annual water quality report

Mamey must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.

Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Mamey for a copy.

Testing your own water

To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by Puerto Rico.
