E. coli contamination at Bayfront and Pier 4 Beach in Hamilton Harbour

Beach closings and/or postings are a regular occurrence at various   beaches around the Great Lakes. Beaches are posted when levels   exceed the Provincial Water Quality Objective (PWQO) of 1     cfu/1  ml. Recent studies have shown that Escherichia coli (E. coli)   are present in pore water of beach sand at frequently posted   beaches. The purpose of this study is to characterize the E. coli   numbers in groundwater of beach sand and adjacent lake water, and   compare E. coli numbers among two beaches in Hamilton Harbour during   the winter and ice-free season. Bayfront Beach and Pier 4 Beach are   potentially impacted by heavy industry and four sewage treatment   plants. We collected groundwater from holes in beach sand and waded   to collect neashore lake water. E. coli numbers were consistently   well above the PWQO. Preliminary evidence show E.coli numbers   correlate to nutrient concentrations in groundwater.     (E. coli); (Escherichia coli); (Hamilton Harbour); (AOC); (area of   concern); (beach closing); (beach closings); (groundwater); (beach   closure); (beach closures)
