to aquatic ecosystems when and where they discharge to surface waters, finds a study from members of Environment Canada's Water Science and Technology Directorate.

The study looks at the application of a laboratory toxicity bioassay to
field-collected samples from contaminated groundwater discharging to an
urban stream. Its objectives were to assess the potential toxicity of
the discharging ground water, while also exploring the suitability of
such standard tests to site ground water and using juvenile freshwater mussels as a test organism.
