INTRODUCTION

Water pollution progresses every day in our lakes, oceans, rivers, and other bodies of water that we see and use in many ways. Water is essential for all living things to survive, yet people still pollute it. It's pretty sad to be taking a trip to the beach with your family and you get there to see a sign that says the beach is closed. Or not being able to eat a fish because it's diseased from pollution. Not all pollution is deliberate though, the definition of marine pollution according to the Group of Experts on the Scientific Aspects of

Some cities also have combined sewers, which may discharge untreated sewage during rain storms.[14]
Pathogen discharges may also be caused by poorly-managed livestock operations.
Chemical and other contaminants
Contaminants may include organic and inorganic substances.
Organic water pollutants include:
• Detergents
• Disinfection by-products found in chemically disinfected drinking water, such as chloroform
• Food processing waste, which can include oxygen-demanding substances, fats and grease
• Insecticides and herbicides, a huge range of organohalides and other chemical compounds
• Petroleum hydrocarbons, including fuels (gasoline, diesel fuel, jet fuels, and fuel oil) and lubricants (motor oil), and fuel combustion byproducts, from stormwater runoff[15]
• Tree and bush debris from logging operations
• Volatile organic compounds (VOCs), such as industrial solvents, from improper storage. Chlorinated solvents, which are dense non-aqueous phase liquids (DNAPLs), may fall to the bottom of reservoirs, since they don't mix well with water and are denser.
• Various chemical compounds found in personal hygiene and cosmetic products
Inorganic water pollutants include:
• Acidity caused by industrial discharges (especially sulfur dioxide from power plants)
• Ammonia from food processing waste
• Chemical waste as industrial by-products
• Fertilizers containing nutrients--nitrates and phosphates--which are found in
