The standard for Arsenic ...
Published by Bob Fadem, Master Water Purification & Treatment Specialist
The standard for Arsenic removal was 50 ppb almost everywhere. Studies on the effects of Arsenic found that levels above 10ppb cause health problems. The EPA in the lowered the standard to 10 ppb from 50 ppb with documented studies. This has caused huge problems in the US, currently there are 4100 Municipal water systems out of compliance with the law at this moment.
I have been working on this issue for 2 years, the solution is being tested as we speak.

it is a small water system problem in the US, and the best solutions are either decentralized point of use treatment, or bottled water for drinking wand cooking if te concentrations are high enough. We successfully demoed decentralize POU in a community of 400 people and showed that the cost was about have of a central treatment facility. It is readily treated by POU with activated alumina and iron oxide systems. They should not be expensive.
