    Water contamination causes acute water borne diseases to humans, animals as well as aquatic organisms. The effect of water contamination is acute and it affects all the sources of water. They can be prevented using effective water treatment methods. In the rest of the following we will show how water gets contaminated, and the effects concerning water contamination.

    Water Contamination:

    Water Contamination affects the following water resources likeness river, lakes, ponds, dams also groundwater. As the sources get contaminated, the contaminated water obtained from them causes serious disorders.

    Water pollution mainly affects

    Drinking water
    Ground water
    Water adulteration may cause due to

    Pathogens
    Chemical substances
    Chemical substances:

    Chemical substances are released by the industries interested water resources and payable to soil erosion. During soil erosion the therapy will take off the nutrients present in the top layer of the soil.

    Pathogens:

    Pathogens are microbial agents like viruses and bacteria which originate from untreated sewage waste. They will cause health problems and diseases to humans.

    Effects of water contamination:

    The following are the effects of water contamination,

    The main acute effect is caused near drinking water contamination. The chemicals secondhand in pipes and joints affect the drinking wet after its treatment. They contain harmful chemicals like copper, tar, zinc and lead. They will cause water borne diseases like cholera, dengue.
    Next effect is groundwater contamination. The waste disposed using landfills; industrial disposal of gasoline, other nuclear wastes gets contaminated with groundwater causes serious about effects.
    The groundwater becomes toxic et alii it is unfit for human use. This will cause serious health impacts like causing cancer, connective acute diseases.
    The water resources contamination affects the life of aquatic organisms. Receivable to the discharge of chemicals the fishes doesn’t get enough oxygen and hence death from aquatic organisms will augmentation natatory contamination.

    Acid rain also leads to the water contamination and it turns spray to be acidic. It also secure skin diseases in humans.

    Water borne diseases due to bacterial and viral infections:

    Bacterial water borne diseases: Clinical features incorporate a wide range of syndromes that include acute dehydrating diarrhoea (cholera), acute cutthroat diarrhoea (dysentery), prolonged febrile illness with abdominal symptoms (typhoid fever), etc. Common agents that are responsible for the spread concerning bacterial water borne diseases are Vibrio cholera, Salmonella, Campylobacter, Shigella and Escherichia coli. Transmission is mainly through lack of allowable maintenance of civic water distribution and contaminated surface water. Cholera is caused near Vibrio cholera with characteristic symptoms of nausea, severe watery diarrhoea, cramps, vomiting, rapid pulse, nose bleeding. In severely affected cases, which are not treated early, hypovolemic shock is experienced which is life threatening within 12-18 hours.

    Viral water borne diseases: Hepatitis A is major viral water borne disease transmitted by drinking contaminated water. Hepatitis A, also called as infectious hepatitis is associated along severe headache, depreciation concerning appetite, fever, abdominal pain, inflammation in the liver also muscle ache. It is usually mild and few untreated cases may prove to be catastrophic caused by permanent liver damage. Polio caused by polio virus leads to paralysis of muscles.

    Parasitic water borne diseases: Most of the water borne diseases caused apart from bacteria and viruses are caused by parasites. Entamoeba histolytica causes amoebic dysentery with symptoms of abdominal pain, headache, fever, chills and severe diarrhoea. It is fatal as compared to bacterial dysentery and is proven fatal if untreated. Schistosomiasis is carried by Schistosoma worm is characterized by abdominal pain, urinal bleeding and diarrhoea.
