What is toxic pollutants in water pollution?
Sources of toxic chemicals include improperly disposed wastewater from industrial plants and chemical process facilities (lead, mercury, chromium) as well as surface runoff containing pesticides used on agricultural areas and suburban lawns (chlordane, dieldrin, heptachlor).
How does toxic chemicals cause water pollution?
When harmful microorganisms and chemical substances contaminate bodies of water, they cause the water quality to decrease and potentially make it toxic. Outside substances, such as pollutants found in wastewater, can disrupt the complicated relationships between species that an ecosystem needs in order to thrive.
What are harmful chemicals that pollute the water?
Power plants discharge lead, mercury, arsenic, cadmium and many other dangerous toxic pollutants into our waterways. These toxins have contaminated over 23,000 miles of rivers and are linked to cancer and neurological damage. They also bioaccumulate in fish and wildlife, further harming public health.

What are the 3 types of water pollution?
Water pollutants can be divided into three major categories: (1) substances that harm humans or animals by causing disease or physical damage; (2) substances or situations that decrease the oxygen content of water, leading to anaerobic decay and the death of aquatic life; and (3) substances that are indirectly harmful.
