Water Pollution Control

Water pollution is an unwelcome concentration of substances that are beyond the environment's capacity to handle, there is therefore need for water pollution control. These substances are detrimental to people and other living things. This is why we need water pollution control. In an undisturbed ecosystem, all substances are processed through an intricate network of biogeochemical cycles, such as the nitrogen and carbon cycles. During these cycles, substances are taken up by plants, move through the food chain to larger and more complex organisms, and when the latter die, are decomposed (broken down) into simpler forms to be used again when they are taken up by plants. Water pollution control is necessary.
