substances remain in the water and make it toxic for aquatic life such as fish. Even biodegradable pollutants have the potential to harm water supplies for extended periods of time. As contamination accumulates, aquatic life in the water begins to suffer. Lakes are particularly vulnerable to pollution because they cannot cleanse themselves as quickly as rivers or oceans do. Factories sometimes turn bodies of water into open sewers by disposing oils, toxic chemicals, and other harmful industrial wastes into them. Mining and oil-drilling operations release corrosive acid wastes into the water. Municipal waste treatment plants have been established to address concerns about water contamination; however, some towns still directly pour untreated sewage into streams, contaminating themIn areas without sewer systems, septic tanks and cesspools can contaminate groundwater and streams with disease-causing organisms. Even when sewage is treated in purification plants, it can still contribute to water pollution if high levels of nitrogen and phosphorus are present. These chemicals are used in the purification process itself. In regions where farm fertilizers are applied, nitrate levels in groundwater increase, making it unfit for consumption. Additionally, agricultural runoff introduces dangerous pesticides as well as oil, dirt, and ice-melting chemicals from city streets into waterways.

Cities also face issues with noise pollution caused by various sources such as car and truck noises within urban areas. The intensity or volume of sound is measured in decibels (dB), with a clap of thunder typically reaching around 100 dB. Sounds at or above 120 dB cause distress and have the potential to damage ears. Noise pollution is prevalent in cities due to the combination of traffic and construction sounds that echo between tall

buildings. This continuous disruptive noise has become an unpleasant reality for urban residents.

Furthermore, certain genres of music—particularly heavy metal rock music played at excessively high volumes—have led to hearing loss among musicians and their audiences.According to research, loud noises can have detrimental effects on both human health and work performance. Excessive noise levels such as loud music or honking car horns can impair brain function and interfere with concentration.
