Urbanization significantly impacts water chemistry by altering both surface and groundwater systems. As cities expand, natural landscapes are replaced with impervious surfaces like asphalt and concrete, leading to increased runoff and reduced water infiltration into the soil. This change results in higher runoff volumes and velocities, which carry elevated loads of pollutants into urban water bodies. These pollutants include heavy metals (lead, copper, zinc) from vehicle emissions, industrial activities, and infrastructure corrosion. Nutrients such as nitrogen and phosphorus mainly come from fertilizers and sewage, while organic compounds like pesticides and pharmaceuticals enter water bodies through runoff and improper disposal. The accumulation of these pollutants degrades water quality in both surface and groundwater systems. Industrial activities and vehicular emissions exacerbate contamination. Factories may discharge pollutants directly into water bodies or release them into the atmosphere, where they eventually settle in water sources. Traffic emissions also deposit heavy metals onto surfaces that are washed into water systems during rain. Additionally, improper waste disposal, including illegal dumping and inadequate sewage treatment, contributes to the pollutant load. Urbanization disrupts natural hydrological cycles, altering water temperature, flow regimes, and sediment transport, which negatively impacts aquatic life and ecosystems. Effective management strategies, such as green infrastructure, pollution control measures, and sustainable urban planning, are essential to mitigate these effects and protect water quality and public health.
