arsenic removal
The current drinking water standard is 0.010 mg/L or parts per million (ppm) for Arsenic. This is equivalent to 10 ug/L (micrograms per liter) or 10 ppb. Long term exposure to drinking water containing arsenic at levels higher than 10 ppb increases the chances of getting cancer, while for lower arsenic water levels the chances are less But if your arsenic level is upto 500 ppb , showering, bathing and other household uses are safe. Arsenic is not easily absorbed through the skin and does not evaporate into the air. So water treatment for arsenic removal also depend on your use.
Arsenic removal methods or systems include anion exchange, reverse osmosis, activated alumina, and other types of adsorptive media filters. Each method has its advantages and disadvantages.
