Natural sources of water pollution include several environmental factors. Runoff from rainfall can carry sediments, nutrients, and pollutants from the land into rivers, lakes, and oceans. Soil erosion contributes to sedimentation, impacting aquatic habitats. Volcanic eruptions can release harmful chemicals and heavy metals into water bodies. Additionally, algal blooms, often triggered by nutrient runoff, can deplete oxygen in water, harming marine life. Wildfires can lead to ash and toxins entering waterways. Animal waste from wildlife can introduce pathogens and nutrients, contributing to water contamination. Understanding these natural sources is essential for developing effective water management and conservation strategies.
