Water pollution occurs when harmful substances are added to water. There are different types of pollutants including disease-causing microorganisms, water soluble acids and salts, and other pollutants like oil, plastic, and pesticides. Water can also be classified as hard or soft depending on if it produces lather with soap, with hard water containing dissolved salts that prevent lathering and soft water typically used in homes lathering easily. Various purification methods like filtration, boiling, and chlorination can be used to remove impurities and pollutants from contaminated water.
Water pollution is distributed globally, affecting various water bodies and ecosystems. It arises from point sources like industrial discharges and sewage outlets, as well as non-point sources such as agricultural runoff and atmospheric deposition. Urban areas often contribute pollutants through stormwater runoff. Contaminants can be dispersed by rivers, currents, and atmospheric processes, impacting lakes, rivers, oceans, and groundwater. Regional variations occur based on industrialization, population density, agricultural practices, and regulatory measures. International waters may also face pollution challenges due to cross-border influences. Addressing water pollution requires coordinated efforts at local, national, and international levels.
