  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...

  • Efficacy of arsenic filtration by Kanchan Arsenic Filter in Nepal

    Groundwater arsenic contamination has caused a significant public health burden in lowland regions of Nepal. For arsenic mitigation purposes, the Kanchan Arsenic Filter (KAF) was developed and validated for use in 2003 after pilot studies showed its effectiveness in removing arsenic.
