OMG! Half-of-the part in India doing this!!

New Delhi, July 31: Here is a shocking news revealed by World Health Organization states that the discharge of toxic elements from industries and landfills and diffuse sources of pollution like fertilisers and pesticides over the years has resulted in high levels of contamination of groundwater with the level of nitrates exceeding permissible limits in more than 50% districts of India.

Apart from nitrate contamination, the presence of fluoride, iron, arsenic and heavy metals has also touched worrying levels, information provided by the government to Parliament reveals.

According to WHO, nitrate in drinking water can cause methemoglobinemia or the decreased ability of blood to carry vital oxygen around the body.

These alarming details, including numbers of affected districts, show that seven of Delhi’s 11 districts have reported excess fluoride, eight excess nitrates, two excess arsenic and three excess lead in groundwater.

Overall, the groundwater is contaminated with the presence of excess nitrate in as many as 386 districts followed by fluoride in 335 districts, iron in 301 districts, salinity in 212, arsenic in 153 districts, lead in 93 districts, chromium in 30 districts and cadmium in 24 districts of different states across India. Many districts have more than one, two or three toxic elements in their groundwater

Though the government noted that "groundwater in major parts of the country is potable", it underlined the contamination in many parts due to presence of one or more toxic elements. "some parts of various states are contaminated by salinity, arsenic, fluoride, iron, nitrate and heavy metals beyond permissible limits of the Bureau of Indian Standards (BIS)," said minister of state for water resources Arjun Ram Meghwal.

Drinking of arsenic-rich water over a long period results in various health effects including skin cancer, cancers of the bladder, kidney and lung, and diseases of the blood vessels of the legs and feet, and possibly also diabetes, high blood pressure, and reproductive disorders, according to WHO.

Similarly, the presence of other chemicals beyond their permissible limits are known to cause severe health hazards in humans and animals.

The chemical quality of groundwater (GW) is monitored once a year by the Central Ground Water Board (CGWB) through a network of about 15,000 observation wells located all over the country.

The monitoring details show that states like Punjab, Haryana, Uttar Pradesh, Tamil Nadu, Telangana and West Bengal reported the presence of all types of toxic elements, including heavy metals, in the groundwater of their one or the other district.
