The impairment of water quality through temperature increase; usually occurs as a result of industrial cooling water discharges.
Forestry Operations & Water Quality] A temperature rise in a body of water sufficient to be harmful to aquatic life in the water.
Generally, the discharge of water heated by industrial processes into natural water bodies. Also, the "waste heat" generated by industrial processes, such as those associated with petrochemical facilities, coke ovens, and flares, that result in large "plumes" of heated ambient air released into the atmosphere.
The addition of abnormal and undesirable amounts of heat to air or water. It is most significant with respect to discharging waste heat from electric generating plants, especially nuclear power plants, into bodies of water.
Water quality is not defined by chemistry alone. If natural waters are withdrawn for use they should be returned to the environment at approximately the same temperature. An increase or decrease in temperature can have an adverse effect upon plants, animals and chemical balances. Returning water to a stream at a different temperature than it was withdrawn is known as thermal pollution. For example, coal-fired power plants use water in the production of steam that turns turbines. That water is then cooled in the large cooling towers before it is returned to the environment.
The addition of heat to a body of water that may change the ecological balance
variance of temperatures above or below the normal condition of the water
could affect the water near a power plant.
pollution of water by the discharge into it of heated waste from industrial or power plants
A harmful increase in water temperature caused by discharging heated coolant water, particularly from electricity generating stations. Harms aquatic life and any interdependent species, such as birds and mammals using the same habitat.
varying temperatures above or below the normal condition.
the addition of warm or cold water to an aquatic ecosystem, significant enough to raise or lower the temperature and cause stress on organisms
The release of heated waters into natural environments, a process that reduces oxygen levels, harming fish and other living organisms.
The pollution of water by excessive heat.
Discharge of heated water from industrial processes that can kill or injure aquatic organisms.
When summer rainfall flows over warm impervious surfaces, it absorbs heat (thermal pollution). If this heated storm water is discharged directly through storm sewers to a coldwater stream or river like the Kinnickinnic River, a rapid and marked temperature increase occurs in the river at the beginning (first flush) of the runoff event. These rapid temperature increases (thermal spikes) may be particularly harmful to macroinvertebrates (aquatic insects), which serve as a critical food source for trout.
An increase in air or water temperature that disturbs the climate or ecology of an area.
a reduction in water quality caused by increasing its temperature, often due to disposal of waste heat from industrial or power generation processes. Thermally polluted water can harm the environment because plants and animals can have a hard time adapting to it.
The discharge of heated water from industrial processes into surface waters; it can alter habitats and affect aquatic plants and animals.
addition of heat energy to the environment. It may be transferred by heated air or water and causes localized temperature increases.
harm to lakes and rivers resulting from the release of excessive waste heat into them.
Thermal pollution is a temperature change in natural water bodies caused by human influence. The main cause of thermal pollution is the use of water as a coolant, especially in power plants. Water used as a coolant is returned to the natural environment at a higher temperature.
