Which of the following is (are) fundamental to the control of inorganic chemicals in drinking water?

The control of inorganic chemicals in drinking water is a multifaceted process that relies on several foundational elements. A sanitary survey is essential as it involves a comprehensive evaluation of the water supply source, the distribution system, and potential contamination sources. This proactive approach helps identify and mitigate risks before they can affect water quality.

Identifying the sources of inorganic chemicals is also fundamental. By understanding where these contaminants originate—be it natural sources like mineral deposits or anthropogenic sources such as industrial discharges—measures can be put in place to prevent or reduce exposure to harmful concentrations.

Furthermore, the detection of amounts of pollutants is critical to ensuring that water quality meets safety standards. Regular monitoring and testing for the presence of inorganic chemicals allow for timely interventions should concentrations exceed safe limits.

Together, these components—sanitary surveys, source identification, and pollutant detection—create a robust framework for effectively managing and controlling the levels of inorganic chemicals in drinking water, making 'all of the above' the comprehensive choice.
