Elevated concentrations of arsenic in ground water are reported from various parts of India but particularly affecting the large parts of the Ganga- Brahmaputra Plains. However the maximum allowable limit was decreased to 50 μgL.
As per BIS IS 105002012 the acceptable limit of Arsenic is 001 mgl and the permissible limit in absence of alternate source is also 001 mgl.
What is the permissible limit of arsenic in drinking water. Drinking Water Arsenic Rule History On January 22 2001 EPA adopted a new standard for arsenic in drinking water of 001 mgl or 10 parts per billion ppb replacing the old standard of 50 ppb. Water systems had to meet the new standard by January 23 2006. The level of arsenic in natural waters including open ocean seawater generally ranges between 1 and 2 µgl Hindmarsh.
Concentrations may be elevated however in areas with volcanic rock and sulfide. In 1963 the 2nd edition of the International Standards for Drinking Water was published which included As in the same category of toxic substances. However the maximum allowable limit was decreased to 50 μgL.
The 3rd edition 1971 of the International Standards reaffirmed the limit of 50 μgL. EPA has set 10 ppb as the allowable level for arsenic in drinking water maximum contaminant level. EPA 2006 The World Health Organization recommends a provisional drinking water guideline of 10 ppb.
Arsenic is used in some veterinary drugs including those used to treat animals used for commercial food products. Giving the example of Lahore Dr Ashraf said if the permissible limit of arsenic was reduced from 50ppm to 10ppm drinking water in the city would be 100pc. 22 Zeilen Drinking water IS 10500.
The acceptable limit of Arsenic is 001 mgl and the permissible limit in absence of alternate source is also 001 mgl. Elevated concentrations of arsenic in ground water are reported from various parts of India but particularly affecting the large parts of the Ganga- Brahmaputra Plains. Arsenic in drinking water permissible limit is 005 mgl as per Indian Standard IS 3025 And as per CPCB guidelines for effluent standards the concentration of Arsenic.

Arsenic has been shown to have significant health effects in some parts of the world eg. Arsenic is one of the few substances shown to cause cancer in humans through consumption of drinking water and there is overwhelming evidence that. Drinking water quality standards describes the quality parameters set for drinking waterDespite the truth that every human on this planet needs drinking water to survive and that water may contain many harmful constituents there are no universally recognized and accepted international standards for drinking water.
Even where standards do exist and are applied the permitted concentration of. In drinking-water supplies arsenic poses a problem because it is toxic at low levels and is a known carcinogen. In 2001 the USEPA lowered the MCL for arsenic in public-water supplies to 10 micrograms per liter µgL from 50 µgL.
PHIt is the measure of hydrogen ion concentrationNeutral water pH-7Acidic water has pH below 7 Basic water has pH above 7Desirable limit 65-85 Issues. Beyond this limit the water will affect the mucous membrane and water. Arsenic is an element found in the Earths crust and it finds its way into food water soil and air.
In 2000 the US. Environmental Protection Agency considered tightening the drinking water standard for arsenic then at 50 parts per billion to as low as 3 ppb. Drinking water is the major pathway for ingestion of arsenic in human system.
As per BIS IS 105002012 the acceptable limit of Arsenic is 001 mgl and the permissible limit in absence of alternate source is also 001 mgl.
