Water Quality Test Results
June, July & August 2021

Call 264.5628 to report Water Quality or Storm Water issues

Testing takes 30 hours to complete. Weekly results are posted on Thursday evenings.

     Water test samples are gathered every Monday and Wednesday mornings and tested for the presence of E.Coli overnight by Endyne Testing of Williston, VT. Those results are returned to the Town Offices the following morning.

SINCE 2013: Water samples with E. Coli levels higher than 235 CFU/100mL indicate water that is unsafe to swim in. High E.Coli can cause intestinal discomfort (gastroenteritis). Individual site readings above 235 CFU/100 ml indicated in RED. When two or more Bayside Beach or Rossetti Nature Area readings are above 235 CFU/100 ml, the beach will be marked as unsafe (signage at the beach entrance) and retested until the readings are acceptable. The followup retesting of those town sites is indicated following each high reading.

      If you have any questions or comments, please call Stef the Water Quality Guy at 264.5628
or email him at sparker@colchestervt.gov
