Water bodies can get contaminated by human activity, commonly referred to as aquatic pollution, which has a negative effect on how the water is used.
Bodies of water include aquifers, reservoirs, lakes, rivers, oceans, and groundwater. Water contamination happens when contaminants are introduced into these bodies of water. The four primary causes of water contamination are sewage discharges, industrial activity, agricultural activity, and urban runoff including stormwater. Surface water contamination and groundwater pollution are the two main categories. For instance, improperly treated wastewater discharged into natural waters may result in the decline of these aquatic ecosystems. People who use unclean water for irrigation, drinking, bathing, or washing run the risk of getting sick from these diseases. A body of water's capacity to deliver ecosystem services, such as drinking water, is decreased as a result of water pollution.
