Abstract
Groundwater is typically a safe source of drinking water due to its stable and good microbial quality. However, the presence of geogenic arsenic (As) in groundwater, poses a serious health concern, impacting hundreds of millions of people worldwide. Prolonged groundwater consumption with elevated As levels can lead to chronic diseases, including cancer. According to the World Health Organization (WHO), As levels in drinking water should be less than 10 μg/L to minimise potential health risks. Consequently, As-contaminated groundwater should be treated before consumption...
