Check Your Learning 1. Name two parts of the water cycle in which contaminants can be introduced. 2. (a) What are the two main categories of contaminants in water? (b) Why are they a problem? 3. Choose two chemical contaminants that could be found in a freshwater source. For each one, (a) identify a source of the contaminant (b) describe how the contaminant got into the water 4. Briefly describe how a biological contaminant was able to get into groundwater wells at Walkerton.
