Isn’t it bad news that concentrations of chlorine and un-ionized ammonia in the Ottawa River exceed Federal guidelines for the protection of aquatic life?
Surface water quality guidelines are usually based on laboratory studies and designed to protect the most sensitive Canadian species, under the worst-case conditions. For example, the guideline for the protection of aquatic life for chlorine is such that any detection of chlorine in a water body would be considered to pose a potential risk. The concentrations for both chlorine and un-ionized ammonia in the river have been below concentrations shown in scientific studies to pose risks to fingernail clams. It should also be noted that concentrations of chlorine upstream of the Pickard Centre have also been measured at levels exceeding guidelines.
