Are all water samples tested for all waterborne diseases? Is this statement true or false?

The statement that all water samples are tested for all waterborne diseases is false because it is impractical and unnecessary to test every sample for a full spectrum of waterborne pathogens. Water quality testing typically focuses on a select group of contaminants that are known to pose health risks, and testing is guided by specific criteria and priorities established by health agencies and regulatory standards. The specific pathogens included in testing can depend on several factors, such as the source of the water, the intended use, and known regional risks.

Moreover, testing for every conceivable pathogen in every water sample would be overly time-consuming, costly, and inefficient. Instead, monitoring programs often target indicators of contamination—such as coliform bacteria—rather than attempting to assess every possible disease-causing organism. This approach allows for effective management of water quality while ensuring public health without the overwhelming resources that universal testing would require.
