An Analysis of Arsenic Contamination in the Groundwater of India, Bangladesh and Nepal

This paper starts by presenting an overview of the Arsenic contamination in the groundwater in different parts of India. The paper goes on to present standards regarding Arsenic in drinking water and then proceeds to give a state-wise status of Arsenic contamination.

Adverse effects of Arsenic on the health of human beings, accumulation of Arsenic in the food chain and ill-effects of using Arsenic-laden water for irrigation are elaborated upon in the paper. The paper proceeds to explore technological options to deliver Arsenic-free water by various ways and means. Providing medical relief to affected people is also included. Methods for safe disposal of Arsenic-laden sludge from Arsenic filters and various issues related to the same are also key aspects of the paper.

1. Thanks Kumar, an interesting brief overview. Regarding the save disposal (or storage until future usage) of arsenic loaden sludge I think you will have to install hazardous waste dump sites like we are using in europe, it is a toxic element and you have to control it even after immobilization.

2. An easy solution would be to use ECP as water disinfectant, meanwhile oxidising the arsenic and many other contaminants. www.bieau.be

3. What are the risks of arsenic related cancers in areas greater than 50 ppb vs below 50 ppb?  What is the daily water consumption in L in the areas?
