Water pollution is caused by many things, but one reason is because we put many chemicals in the rivers In the essay on water pollution: Sources, Effects and control of water pollution, by Puja Mondal explains “ several types of liquid effluents contaminating toxic chemicals, acid and bases, are added to the rivers and other water bodies. This quote explain how this toxic chemicals contaminated or water. Other thing that cause water pollution are the factories they contaminated a lot or water. In the essay on water pollution: sources, effects and control of water pollution by Puja Mondal, explains “ Many industrial are causing thermal pollution leading to higher temperatures… They use a lot of water to the steam at higher temperature, which affect the biotic components in the aquatic habit. This quote explain how this industries contributed to water pollution.
Water pollution is getting worse and worse nowadays. From plastic bag to harmful substance, things that we produce on land already reaches to the sea, either by deliberate dumpling or run-off through drains and river. For example, oil, toxic and rubbish. Oil that spill into the ocean will poison the organism in the marine. It will also cause the animal to not be able breathe properly under the sea (West, 2017).
This occurs because excess nutrients can fuel the growth of algae blooms that block sunlight from reaching underwater grasses and, during decomposition, rob the water of oxygen that plants and animals need to survive. Certain species of algae that are common in bodies of water plagued by eutrophication can also contaminate shellfish. When consumed by humans, these diseased aquatic invertebrate cause paralytic shellfish poisoning: a potentially fatal disease. Unfortunately, though there are many drawbacks and negative effects on the water quality in the Bay, no real benefits are found in the water when agricultural pollution is present. The most destructive components of agricultural pollution are livestock manure, poultry litter, and chemical fertilizers.
Direct sources of water pollution include runoff, industrial waste, sewage, and human waste. Indirect sources include air pollution and sediment from construction sites. Industrial waste can lead to air pollution, which can ultimately lead to the pollution of water. This is also called atmospheric pollution. Atmospheric pollution is caused by pollutants such as smoke from factories entering the atmosphere and being carried to waterways.
Heavy metals from motor vehicles and acid mine drainage Use of water as a coolant by power plants and industrial manufactures leads to thermal pollution Effects of Water Pollution: Ground water contamination through pesticides causes reproductive damage within wild life in echo system. Disturbance in the natural ecological balance due to sewage, fertilizer and agricultural runoff containing organic materials into water and in turn increases the growth of algae which leads to depletion of ozone layer. Industrial chemicals and agricultural pesticides that got mixed up in water bodies’ effects aquatic environment and can accumulate with the fishes which are later eaten by humans, if the fishes are poisoned by the pollutants, interferers with the development of the nervous system in fetuses and young children. Water pollution leads to flooding, because of the accumulation of solid waste and soil erosion in streams and rivers. As Oil spills does not dissolve in water, it leads to suffocation for aquatic habitat.
This has caused the majority of sea turtles to be endangered. As you can clearly see, this has put a huge effect on sea turtle’s lives. Although many of them have been killed, they aren’t the only ones affected by this. Many other fish spices have been hit. Salmon sales have gone down because they’ve been dying.
The rainwater that washes away the chemicals, sediments, motor oil, antifreeze pollutants, and fertilizers ends up in the nearest beaches and causes a huge environmental risk. At the combined sewer plants, untreated domestic and industrial waste water overflows during a rainy season and ends up into the streams and beaches. Similarly, sanitary systems are affected by blockades, line breaks, sewer defects and leaks, inadequate design and vandalism, and lapses in maintenance to force the polluted water to make its way to the streams and beaches. The combined grease, chemicals, nutrients, mixture of raw sewage, industrial wastewater, harmful metals, and bacteria have resulted in the closing of several beaches, shellfish bed closing, and aesthetic and environmental problems (“Sources of Beach Pollution”). Moreover, the discharges from recreational and commercial vessels such as trash, fishing gear, ballast water, domestic waste, paints, and other chemicals are also a source of pollution for the beaches as an increased number of such vessels contributes towards the accumulation of waste and pollution from them.
Water pollution can affect many aspects on the earth where seventy percent of it is actually water. These effects can be boiled down into three main categories, on the ocean, the environment and on the health. Oil spills in the ocean: Animals living in the water are the species that are mostly affected by oil spills in the ocean. Many of the living species will face extinction on the account of the increase of the oil spills by ingesting them. Every year in the Persian Gulf, oil is annually spilled at a rate of 285 million gallons and 1.3 million barrels per year according to the United Nation Estimates (1, 2).
With sufficient thoughts about finding causes for water pollution, it is easy to come up with plenty of causes. However, industries, chemicals and municipals are the three major causes that have negative effects on water’s pollution. Causes Industry: Industrial water
Swimming and drinking in contaminated water can cause skin diseases and also can lead to cancer, reproductive problems, and typhoid fever and stomach ailments in humans? Highly polluted water can harm internal organs like heart and kidneys. Synthetic organs cause serious damage to human health.

Nitrate contamination can prove fatal for infants as it can restrict the oxygen to the reach the brain causing the blue- baby syndrome.
