What laboratory test is frequently performed to analyze water quality?

The pH level test is essential in analyzing water quality because it measures the acidity or alkalinity of the water. The pH scale ranges from 0 to 14, where values below 7 indicate acidity, values above 7 indicate alkalinity, and a value of 7 is neutral. Understanding the pH level is crucial because it can affect the solubility and availability of nutrients and contaminants in water, ultimately influencing aquatic life and the suitability of water for various uses, such as drinking, irrigation, and industrial applications.

While the chlorine residual test is important for assessing water disinfectant levels, and the nitrate concentration test is vital for determining water pollution from agricultural runoff, the pH level test provides a foundational understanding of water chemistry, making it a frequently performed test in water quality analysis. The hardness level test, which assesses the concentration of calcium and magnesium, is also relevant but is more specific to the physical properties of water rather than its overall quality.
