cause of the water pollution by pathogens and organic wastes
Answers
WATER POLLUTION:
Water is essential for life without water there would be no life usually take water as granted for its purity but we must ensure the quality of water pollution of water or genius from human activities.
CAUSES OF WATER POLLUTION BY:
1) PATGOGENS; the most serious water pollutants are the diseases causing agents called pathogens this pathogens include bacteria and the other organisms that enter water from domestic sewage and animal excreta human excreta contain bacteria such as ESCHERICHIA COLI and STREPTOCOCCUS FAECALIS which cause gastrointestinal diseases.
2) ORGANIC WASTES:
The Other major water pollutants is organic matter such as leaves, grass ,trash etcccc
the pollute water as a consequence of run of excessive phytoplankton growth within area is also cause of water pollution is waste of biodegradable

Water pollution:
The contamination of water bodies such as rivers, lakes, etc. due to several contaminants being discharged in them, directly or indirectly, is known as water pollution.
Pathogens
One of the most severe pollutants is the disease-causing microorganisms called pathogens. Pathogens are mostly bacteria, virus, and protozoa. Although bacteria are considered harmless if not beneficial, there are a few of pathogenic bacteria as well which enter the water bodies through sewers and sanitation systems.
Organic Wastes
Organic water pollutants include food waste, detergents, leaves, grass, etc. They originate from domestic sewage, discharge from food processing factories and farm wastes which reach the water sources through runoff and pollute them. It is a fact that the bacteria decompose the complex organic matter into the simple organic matter.
Chemical Pollutants
Chemical pollutants include heavy metals such as mercury, lead, cadmium, etc., solvents from industries, pesticide run-offs, oil spills through ships, etc. They are poisonous to aquatic life forms and cause their infertility and death.
