PCR contributes to our understanding of many environmental issues, particularly where the detection of microorganisms in the environment is required. PCR allows specific target species to be identified and quantified, even when very low numbers exist. One common example is searching for pathogens or indicator species such as coliforms in water supplies.
To think about:
As a population, we are becoming more aware of the importance of water quality. Whose responsibility should it be to monitor water quality? Who should be allowed access to information about water quality? Whose responsibility should it be to maintain good water quality?
