MONKTON — Water quality tests done by the Lewis Creek Association late last week have determined that two swimming sites in northern Addison County are currently unsafe for swimming.
The sites, along Lewis Creek at Route 7 in Ferrisburgh and Tyler Bridge Road in Monkton, tested for unsafe levels of E. coli.
The E. coli levels at Tyler Bridge were 686.7 MPN per 100ml, the unit of measurement used to detect E. coli colonies. The Route 7 site tested at 272.3 MPN per 100ml. The state standard is 77 MPN per 100ml.
