Water pollution. Water pollution or aquatic pollution

Non-biodegradable organic compounds
Non-biodegradable organic substances can enter water bodies from a variety of sources, for example industrial wastewater. Many of these chemical substances are toxic.^[10]: 229

• 
  Chemicals from insecticides and herbicides.
  
• 
  Petroleum hydrocarbons, including fuels (gasoline, diesel fuel, jet fuels, and fuel oil) and lubricants (motor oil), and fuel combustion byproducts, from oil spills or storm water runoff^[11]
  
• 
  Volatile organic compounds, such as industrial solvents, from improper storage.
  
• 
  Persistent organic pollutants, for example per- and polyfluoroalkyl substances (PFAS),^[12][13]
  
• 
  Organochlorides, polychlorinated biphenyl (PCBs), trichloroethylene, perchlorate (these are currently or were in the past used as pesticides, solvents, pharmaceuticals, and industrial chemicals).
  

The following compounds can all reach water bodies via raw sewage or even treated sewage discharges:

• 
  Various chemical compounds found in personal hygiene and cosmetic products.
  
• 
  Environmental persistent pharmaceutical pollutants, which can include various pharmaceutical drugs and their metabolites (see also drug pollution), such as antidepressant drugs, antibiotics or the contraceptive pill.
  
• 
  Metabolites of illicit drugs (see also wastewater epidemiology), for example methamphetamine and ecstasy.^[14][15]
  
• 
  Disinfection by-products found in chemically disinfected drinking water (whilst these chemicals can be a pollutant in the water distribution network, they are fairly volatile and therefore not usually found in environmental waters).^[16]
  
• 
  Hormones (from animal husbandry and residue from human hormonal contraception methods) and synthetic materials such as phthalates that mimic hormones in their action. These can have adverse impacts even at very low concentrations on the natural biota and potentially on humans if the water is treated and utilized for drinking water.^[17][18][19]
