According to eNotes sources, the primary causes of water pollution are pathogens, organic and inorganic contaminants, macroscopic, and thermal pollutants. Examples of organic contamination include detergents, insecticides, petroleum and other industrial solvents. Inorganic contamination can come from acidic buildup, chemical waste, fertilizers and sediment.
