VARANASI, INDIA — A team of researchers at the Banaras Hindu University (BHU) in India have developed a microbe-based treatment solution for removing arsenic from groundwater, according to Yahoo! News.
The human-friendly bacteria, Lactobacillus acidophilus, was shown to have the capacity to remove arsenic from contaminated water up to a level of 0.8 ppm within a three-hour time period, the article stated.
One advantage of the natural cleaning agent is that the bacteria is able to survive in a toxic concentration of arsenic even after absorption, according to the story.
“Until now most of the works carried out to remove arsenic from groundwater was through physiochemical processes, but they produced wet bulky sludge and required final filtration for secondary treatment,” said Dr. Asha Lata Singh, an assistant professor of environmental science at BHU’s Department of Botany.
