Annual water quality report

Roark Estates Water Assoc 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 Roark Estates Water Assoc for a copy.

Find a posted report with EPA's Consumer Confidence Report search
