There are several methods to detect water pollution, here are some of them:
- Water sampling: Taking a sample of water from a river, lake, or ocean to test its quality.
- pH testing: Checking the acidity or alkalinity of the water using pH paper or a meter.
- Biological testing: Counting the number of tiny living organisms, like bacteria or insects, that live in the water.
- Chemical testing: Measuring the amount of chemicals like nitrogen, phosphorus, or heavy metals in the water.
- Visual inspection: Looking for signs of pollution, like foam, oil spills, or strange colors.
- BOD (Biochemical Oxygen Demand) testing: Measuring the amount of oxygen needed to break down organic waste in the water.
