What does a low pH level indicate about the water?

A low pH level in water indicates that the water is acidic. The pH scale ranges from 0 to 14, where values below 7 are considered acidic, values at 7 are neutral, and values above 7 are basic or alkaline. When the pH drops below 7, it signifies an increase in hydrogen ion concentration, making the water acidic.

Acidic water can lead to various environmental and health concerns. For instance, it can deteriorate infrastructure and aquatic ecosystems, harm fish and other aquatic life, and lead to the leaching of heavy metals from pipes and sediments, which could pose health risks.

Understanding the implications of low pH is crucial in wastewater treatment, as water with a pH that is too low may require neutralization interventions before it can be safely released into the environment or further processed.
