Arsenic - What can you and I do?

Worldwide, approximately 783 million people do not have access to safe water. This is due to contamination of water by chemical and biological pollutants. One of the sources of contamination is the naturally occurring chemical arsenic (As) in groundwater. Currently, over 100 million people worldwide are exposed to this toxic concentration in groundwater supplies (especially tube well), the vast majority living in rural Bangladesh and India (West Bengal, Bihar). Other highly arsenic-affected areas are found in Vietnam, Thailand, Argentina, Chile, Mexico, China and the United States.

The slow accumulation of arsenic in the body causes multiple types of cancer, cardiovascular diseases, skin lesions, gangrene, reduced IQ in children, neuropathy and finally - premature death.

Although the WHO’s recommended maximum limit for arsenic in drinking water is 10 parts per billion (ppb), the arsenic levels can exceed 1000 ppb. Hundreds of thousand people in the above mention countries are already showing signs of arsenic poisoning, in what is rightly called the largest case of mass poisoning in history. A recent 10-year long cohort study published in The Lancet showed that 1 in 5 of all adult deaths in Bangladesh are now due to arsenic.

At WEALL.CARE consist of volunteers around the world with different profession backgrounds, we’re all sharing a common goal - Helping Those in Need. To combat this invisible killers (arsenic), we focus on the following objectives:

  • Create various awarness programs to educate people about the danger of arsenic in drinking water, specially tubewell water.
     
  • Continous developing a low cost arsenic remediation method.
     
  • Share our findings with other researchers world wide.
     
  • Creating teams as they isolate contaminated tube wells.
     
  • Assist local government in combat the arsenic contamination.

    Currently, headed by Dr. Mai Thanh Truyet Ph.D. with the assist of many others around the world, he has developed an effective solution using adsorption and translocation using dry plant. This little to no cost solution can reduce over 90% of arsenic at a rate of 1 gallon in every 10 minutes. We are developing multiple different prototypes that can be easily put in use in rural areas.

    Two other methods we are following closely are ARUBA (arsenic removal using bottom ash) and ECAR (electrochemical arsenic remediation) headed by scientists at Berkeley Lab, in collaboration with UC Berkeley.

    Berkeley Lab researchers estimate the cost of just the technical arsenic remediation of 10 liters of water per day (needed per person) to be about $1 annually using the ECAR method and between $7 and $15 annually using the ARUBA method. (ECAR needs a small amount of electricity, while ARUBA does not.)

    As you can see, there are more organizations worldwide that are continuously finding ways to combat this invisible killer.
