Thermal pollution, caused by the discharge of heated water from power plants or industries into water bodies, significantly alters aquatic ecosystems and harms aquatic life.

Thermal pollution is defined as the degradation of water quality by any process that changes ambient water temperature, typically through the use of water as a coolant by power plants.

In an anticline oil trap, fluids separate based on density. Natural gas is the least dense and accumulates at the top, followed by oil, and then groundwater at the bottom.

The presence of nitrogen in sewage, often in the form of proteins or urea, is a primary indicator of organic matter content.

Chemical Oxygen Demand (COD) is a measure of the amount of oxygen required to chemically oxidize organic compounds in water, commonly used to assess the strength of sewage.

Water pollution is considered a critical hazard because water is essential for all life forms, and its contamination directly impacts human health and global ecosystems.

Mining, agro-industries, and thermal power plants all contribute significantly to water and soil pollution through chemical runoff, heavy metals, and thermal discharge.

Nuclear power plants use water for cooling purposes. The discharge of this water back into the environment at elevated temperatures causes thermal pollution.
