Water Pollution Water Pollution Water Pollution. The pollutants that affect water come mainly from industries, farms, and sewerage systems.
Industries dump huge amounts of waste products into bodies of water each year.
These wastes include chemicals, wastes from animal and plant matter, and hundreds of other substances. Waste from farms includes fertilizers, pesticides, and animal wastes. Most of these materials drain off farm fields and into nearby bodies of water. Sewerage systems carry wastes from homes, offices, and industries into the water. Nearly all cities have waste treatment plants that remove some of the most harmful wastes from sewage.
