The City of Hamilton has implemented a Quarterly Chedoke Creek Sampling Program that samples Field Dissolved Oxygen and Temperature, and the laboratory analyte Escherichia coli (E. coli).

Live map is updated monthly providing current information for each water sample location.
Hamilton Harbour Surface Water Quality Monitoring Criteria
Temperature of the surface water is an important field parameter as it directly influences water chemistry and influences the dissolved oxygen (DO) content; determining the types of organisms that can survive in the water.
|The temperature of the surface water is used to calculate other select field and laboratory analytical parameters.||Ministry Environment, Conservation and Parks - Water Management: Policies, Guidelines and Provincial Water Quality Objectives|
|Field Dissolved Oxygen:
Dissolved Oxygen (DO) is an important water quality indicator as it directly influences the organism that live within the water body (including fish, invertebrates, bacteria and plants). DO is directly influenced by water temperature, streamflow, wind strength & direction and the season. A dissolved oxygen level that is too high or too low can harm aquatic life and overtime, affect water quality.
|≥ 5 mg/L for cold water biota
≥ 4 mg/L for warm water biota

|Escherichia coli (E. coli) bacteria:
E.coli is a type of fecal coliform bacteria that is commonly found in the intestines of warm-blooded animals and humans. E coli is used as an indicator for the presence of sewage or animal waste in surface water (Tchobanoglous & Schroeder 1987)
