What is fundamental for the control of chemicals in drinking water?

• A. Surface water testing only
• B. Removal of all natural minerals
• C. Sanitary survey and identification of sources
• D. Regular chlorination of water

Answer: (C)

The control of chemicals in drinking water is fundamentally reliant on conducting a sanitary survey and identifying sources. This process allows for a systematic assessment of potential contamination sources within a water supply system, including agricultural runoff, industrial discharge, and other pollutants that could compromise water quality. By identifying these sources, water management authorities can implement effective strategies to mitigate risks, ensuring that the drinking water remains safe for public consumption. A sanitary survey involves evaluating the entire water supply system, from source to tap, considering factors such as water treatment practices, distribution systems, and potential contamination points. This comprehensive understanding is crucial in developing targeted measures to manage and monitor water quality effectively. In contrast, focusing solely on surface water testing does not provide a complete picture of all potential chemical hazards, as it may overlook contamination from groundwater or other sources. The removal of all natural minerals is neither practical nor desirable, as certain minerals are beneficial for health. While regular chlorination of water is important for disinfection, it does not address the underlying issue of identifying and controlling chemical contaminants before they enter the water supply.
