What produces water pollution

Water pollution

oil pollutionAny actions performed by a person with water lead to a change in both its physical properties (for example, when heated) and the chemical composition (in places of industrial effluents). Over time, the substances trapped in water are grouped and remain in it already in the same state. The first category includes domestic and most industrial wastewater. The second group includes various types of salts, pesticides, dyes. Let's look at some of the pollutants at a closer distance.


This is one of the main factors affecting the state of water. Fluid consumption per person per day in America is 750 liters. Of course, this is not the amount you need to drink. A person consumes water when washing, uses it for cooking, uses the toilet. The main drain goes down the drain. At the same time, water pollution increases depending on the number of residents living in the village.Each city has its own sewage treatment plant, in which sewage is cleaned from bacteria and viruses that can seriously harm the human body. The purified liquid is discharged into the rivers. Water pollution by household wastewater is increasing and because, in addition to bacteria, it contains food debris, soap, paper and other substances that negatively affect its condition.


chemical pollution of waterAny developed state should have its own factories. This is the largest factor contributing to water pollution. The liquid is used in technological processes, it serves both for cooling and for heating the product, various aqueous solutions are used in chemical reactions. More than 50% of all discharges come from four major liquid consumers: oil refineries, steel and blast-furnace plants, and pulp and paper industry. Due to the fact that the disposal of hazardous waste is often an order of magnitude more expensive than their primary treatment, in most cases, along with industrial effluents, a large number of various substances are discharged into water bodies. Chemical pollution of water leads to disruption of the entire ecological situation in the whole region.

Heat exposure

Most power plants use steam energy in their work.Water in this case acts as a cooler, after passing through the process, it is simply discharged back into the river. The temperature of the flow in such places may increase by several degrees. Such an impact is called thermal pollution of water, but there are a number of objections to this term, since in some cases a rise in temperature may lead to an improvement in the environmental situation.

Water pollution by oil

water pollutionHydrocarbons - one of the main sources of energy on the entire planet. Wrecks of tankers, gusts on oil pipelines form a film on the water surface through which air cannot flow. Spilled substances envelop the marine inhabitants, which often leads to their death. Both volunteers and special equipment are involved in the elimination of pollution. Water is a life-giving source. It is she who gives life to almost every creature on our planet. Careless and irresponsible attitude to it will lead to the fact that the Earth will simply turn into a desert burned out by the sun. Already, some countries are experiencing a shortage of water. Of course, there are projects to use the Arctic ice, but the best solution to the problem is to reduce the overall water pollution.
