What is commonly tested in water samples to ensure it is safe for drinking?

In assessing the safety of drinking water, both pH and chlorine levels play crucial roles.

The pH level indicates the acidity or alkalinity of the water, which can affect not only the taste but also how well the water can react with other substances. A pH level that is too low (acidic) or too high (alkaline) can lead to corrosion of pipes or leaching of metals such as lead or copper, posing health risks. Maintaining a balanced pH level is essential for the overall quality of drinking water.

Chlorine levels are also critical because chlorine is commonly used as a disinfectant in water treatment processes. It helps eliminate harmful bacteria, viruses, and other pathogens that could lead to waterborne diseases. Ensuring adequate chlorine levels confirms that the water remains safe during storage and distribution.

Since both of these parameters are vital for ensuring the microbiological safety and chemical composition of drinking water, testing for both pH and chlorine levels is a standard practice in water quality management. Total dissolved solids, while important, serve a different purpose in assessing water quality and do not directly correspond to the microbiological safety that pH and chlorine levels ensure.
