Where the water comes from
Green Isle draws water from 2 wells (1 of them for emergency, seasonal or other part-time use).
Annual water quality report
Green Isle 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.
Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
