Which is true about bacteriological water quality standards?

Bacteriological water quality standards are primarily designed to protect public health by ensuring that the water is safe from harmful biological contaminants, such as bacteria, viruses, and parasites. These standards set specific limits on the presence of certain microorganisms in water supplies, which is crucial for preventing waterborne diseases and ensuring the potability of drinking water.

While chemical contaminants are also regulated, bacteriological standards focus exclusively on biological hazards, highlighting a distinct area of concern in water quality management. This specificity reinforces the importance of assessing and maintaining the microbiological integrity of water supplies as part of a comprehensive approach to water quality. As such, understanding and adhering to these bacteriological standards is a critical aspect of water treatment and distribution for public safety.
