How are pathogens detected in water?
Polymerase chain reaction (PCR) is one of the main alternative detection methods being trialed. PCR has been shown to be a rapid, highly sensitive and accurate method. It has already been used experimentally to detect pathogenic viruses, bacteria and protozoa in water and wastewaters.
What are some pathogens found in water?
