Summary of 2017 Beach Water Monitoring Report
All Huron County beaches were sampled a minimum of 23 days. At Goderich Main beach, 39 per cent of the sample days had an E. coli geomean concentration exceeding the provincial beach water standard of 100 E. coli CFU/100 ml (Table 2). When summed, Huron County beaches exceeded the provincial standard on 21% of the days sampled. The daily geomeans for each beach are contained in the Beach Water Monitoring Report.
Table 1: Number of days Huron County public beaches were sampled in 2017 and per cent of sampling days exceeding provincial limit for E. coli
|Beach||Number of sample days exceeding 100 E. coli CFU/100 ml||Total number of sample days||Per cent sample days exceeding 100 E. coli CFU/100 ml|
|Ashfield Township Park||11||29||38%|
|Goderich – Main||13||33||39%|
|Goderich – Rotary Cove||10||29||34%|
|Goderich – St. Christopher’s||9||30||30%|
|Hay Township Park||2||25||8%|
Five, three, and one year E. coli CFU/100 ml geomeans were calculated for each beach (Figure 1). Goderich Main Beach and Goderich St. Christopher’s Beach had the highest five year, three year, and and one year geomeans.
