Answer:
5 Major Water Pollutants:
1.MICROBIAL:
Pathogens can be bacteria, protozoa or viruses. Bacteria, for example, are commonly found in water. However, when they start to increase above safe levels, water contamination occurs.Pathogen discharges may also be caused by poorly managed livestock operations. The presence of E. coli bacteria usually indicates that water has been contaminated with human or animal waste.
2.ORGANIC MATERIAL
ORGANIC MATERIALOrganic materials are things like petroleum, insecticides and herbicides, detergents, disinfecting cleaners, and prescription drugs.Water contaminated with this organic chemical can cause leukemia, lymphoma and tumors in the testicles, thyroid glands and kidneys.
3.INORGANIC MATERIAL
INORGANIC MATERIALInorganic materials include things like ammonia, chemical waste, fertilizers, and heavy metals. Heavy metals like arsenic, mercury, copper, chromium, zinc and barium — though harmless in very small amounts, act as pollutants when they end up concentrated in water.This kind of water pollution, especially in higher concentrations, can cause severe health problems in humans and other organisms, including death.
4.MACROSCOPIC
MACROSCOPICMacroscopic pollutants are large, visible items in waterways or bodies of water. Trash, either intentionally dumped into bodies of water, or discarded on the ground and washed by rainfall into storm drains, are eventually discharged into waterways.These larger pollutants must be removed in order to avoid disruption of aquatic ecosystems and contamination upon the chemical breakdown of these objects.
5.THERMAL
THERMALThermal pollution is the rise or fall in the temperature of a natural body of water caused by human influence. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers.Elevated water temperatures decrease oxygen levels, which can kill fish and alter food chain composition, and reduce species biodiversity. Urban runoff may also elevate temperature in surface waters.
