PUBLIC BATHING BEACH E. COLI BACTERIA LEVELS FOR GENESEE COUNTY LAKES.
September 27, 2002
The advisory that was in effect for Mott Lake, Bluebell Beach has been
lifted. The E. coli levels are now in compliance with State
guidelines for bacterial concentrations at bathing beaches.
The Genesee County Health Department advises against total
body contact (swimming) at :
- Lake Linda - Outdoor Adventures Beach due to elevated E. coli
All other monitored Genesee County lakes are currently in compliance
with State guidelines for bacterial concentrations at bathing beaches.
Exposure to any recreational water can be a potential health risk.
Gastrointestinal and dermatological illnesses have been associated with
recreational water exposure.
Your Genesee County Health Department utilizes the following rules to
interpret the E. coli test results (By authority conferred on the director
of public health by section 12544 of Act No. 368 of the Public Acts of
1978, as amended, being S333.12544 of the Michigan Compiled Laws) :
R 325.2102 Sanitation and safety
determinations, Rule 2. (1) Bacterial concentrations in water at a bathing beach, as
determined by standard methods, shall contain not more than 130
Escherichia coli (E. coli) per 100 milliliters, as a 30-day geometric
mean. Compliance shall be based on the geometric mean of all individual
samples taken during 5 or more sampling events representatively spread
over a 30-day period. Each sampling event shall consist of 3 or more
samples taken at representative locations within a designated sampling
area. Bathing beach waters shall not contain more than a maximum of 300 E.
coli per 100 milliliters. Compliance shall be based on the geometric mean
of 3 or more samples taken during the same sampling event at
representative locations within a defined sampling area.
