Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence. Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. [1]
With the temperature of the nearby buildings sometimes reaching a difference of over 50 °F (28 °C) from the near-surface air temperature, precipitation warms rapidly, and run-off into nearby streams, lakes and rivers (or other bodies of water) to provide excessive thermal pollution. The increase in thermal pollution has the potential to ...
Thermal pollution, is a temperature change in natural water bodies caused by human influence, such as use of water as coolant in a power plant. Visual pollution, which can refer to the presence of overhead power lines, motorway billboards, scarred landforms (as from strip mining), open storage of trash, municipal solid waste or space debris.

1948 Donora smog. / 40.17624; -79.85547. The 1948 Donora smog killed 20 people and caused respiratory problems for 6,000 of the 14,000 people living in Donora, Pennsylvania, [2] a mill town on the Monongahela River 24 miles (39 km) southeast of Pittsburgh. The event is commemorated by the Donora Smog Museum .
Cooling ponds are used where sufficient land is available, as an alternative to cooling towers or discharging of heated water to a nearby river or coastal bay, a process known as “once-through cooling.”. The latter process can cause thermal pollution of the receiving waters. [1] [2] Cooling ponds are also sometimes used with air ...

Preassembled process unit for air pollution control, i.e., a thermal oxidizer, being installed at a work site. Schematic of a basic thermal oxidizer A thermal oxidizer (also known as thermal oxidiser , or thermal incinerator ) is a process unit for air pollution control in many chemical plants that decomposes hazardous gases at a high ...
