Tao Guangfa, a 67-year-old Chinese villager, still remembers how people used to be afraid to eat corn, rice and other crops in the fields and along a waterway around a local arsenic mine.

Question raised in Lok Sabha on Chemical Contamination of Water, 27/06/2019. State-wise details of areas affected by Arsenic and other contaminants viz. Salinity, Fluoride, Nitrate, Lead, Cadmium and Chromium in ground water, as per data available with CGWB are given at Annexure.

Arsenic is a naturally occurring trace element found in rocks, soils and the water in contact with them. Arsenic has been recognized as a toxic element and is considered a human health hazard. The occurrence of Arsenic in ground water was first reported in 1980 in West Bengal in India.

The report entitled "Report on Ground water quality in shallow aquifers in India" summarizes various aspects of ground water quality in the shallow aquifers in the country with special reference to six parameters viz. salinity, chloride, arsenic, fluoride, iron and nitrate.

This study assesses the current state of knowledge and perceptions of arsenic contamination in rice among different stakeholders in Cambodia and identifies major knowledge gaps and possible policy responses to the issue.

Watermelon rind, usually discarded as waste, has been shown by researchers in Pakistan to be capable of cheaply and efficiently removing arsenic from groundwater.

Water quality in Delhi is on alarming situation, as per a recent Lok Sabha secretariat reports east and northeast districts of Delhi are undergoing arsenic contamination of groundwater, furthermore

Continuously flooded rice systems are a major contributor to global rice production and food security. Allowing the soil to dry periodically during the growing season (such as with alternate wetting and drying irrigation - AWD) has been shown to decrease methane emissions, water usage, and heavy metal accumulation in rice grain. However, the effects of AWD on rice yields are variable and not well understood.

In middle Gangetic plain, high arsenic concentration is present in water, which causes a significant health risk. Total 48 morphologically distinct arsenite resistant bacteria were isolated from middle Gangetic plain. The minimum inhibitory concentration (MIC) values of arsenite varied widely in the range 1–15 mM of the isolates. On the basis of their MIC, two isolates, AK1 (KY569423) and AK9 (KY569424) were selected.
