Sustainability of in Situ Treatment of Underground Water Containing Arsenic

A laboratory setup for studying the in situ process of removing arsenic from underground water is prepared. The experiments were performed with a varying ratio of arsenic and iron, the latter acting as an adsorbing agent. The arsenic concentration of each of the solution is measured after a span of time. The change in concentration of arsenic is then used as a parameter to analyze the performance of adsorbent and for the qualitative analysis of the sand-bed.
