What Do Coal Power Plants Put Into Water

Coal power plants are a major source of energy production that involves the combustion of coal to generate electricity. Although it has been a reliable source of electricity for many years, it is also one of the most significant sources of water pollution. The wastewater discharge from coal power plants contains a variety of harmful pollutants that can be detrimental to human health and the environment if not properly treated.

Heavy Metals

One of the most common and dangerous pollutants in wastewater from coal power plants is heavy metals. These metals include mercury, lead, arsenic, chromium, and cadmium, which are all known to be highly toxic to both humans and aquatic life. When released into waterways, they can accumulate in fish and shellfish, which can then be consumed by humans. Exposure to heavy metals can cause a range of health issues, including neurological and developmental problems, cancer, and kidney damage.

Sulfate

Coal combustion also produces a significant amount of sulfate, a compound that contributes to acidification of waterways. When sulfate levels in water are high, they can have a detrimental effect on aquatic life, especially species that require a specific pH level to survive. Additionally, acidic water can corrode pipes, posing a risk to public health if it contaminates drinking water supplies.

Chlorides

Another common pollutant in wastewater from coal power plants is chlorides, which are found in coal and are released during the burning process. Chlorides can cause corrosion in pipes and infrastructure, but in high concentrations, they can also be harmful to aquatic life. They have been shown to impair the growth and reproduction of fish and can accumulate in the tissues of fish and other aquatic organisms, leading to the consumption of contaminated seafood by humans.

Suspended Solids

Coal power plants also produce high levels of suspended solids in their wastewater. These solids include ash, soot, and other particles that are not properly captured during the combustion process. When these solids are released into waterways, they can smother aquatic habitats, reducing oxygen levels and harming fish and other organisms. Additionally, suspended solids can clog the gills of fish, leading to suffocation and death.

Conclusion

In conclusion, coal power plants are a significant source of water pollution due to the discharge of wastewater containing a variety of harmful pollutants. Heavy metals, sulfates, chlorides, and suspended solids are all common pollutants in this wastewater, and they can have detrimental effects on both human health and the environment. It is essential for coal power plants to properly treat their wastewater to reduce the harmful impacts of their operations on waterways and aquatic life.
