Where the water comes from
Aquinnah Wampanoag draws water from 4 wells.
Annual water quality report
Aquinnah Wampanoag 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 Aquinnah Wampanoag for a copy.
Find a posted report with EPA's Consumer Confidence Report search
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 EPA Region 1.
