What is the arsenic content of ECAR-treated water? Are any contaminants added in the ECAR process?
ECAR treatment is capable of reducing arsenic to below 2 ppb (or possibly lower). The World Health Organization recommends a maximum arsenic concentration of 10 ppb in drinking water. Our design goal is to consistently produce less than 5 ppb. No additional contaminants appear in the treated water. ECAR treatment alone does not remove biological contamination. It can, however, be easily integrated with UV disinfection technology. We note here that the provision of drinking water to the community has to be accompanied by: (1) appropriate community education in health and hygiene practices, and (2) the introduction (if necessary) and use of narrow-mouthed vessels by the households for collection, transport, and storage of water to reduce the possibility of recontamination.
