Kimberlite tailings for the presence of total arsenic. The arsenic contamination of groundwater was found to be location specific in North 24-Parganas district. The maximum arsenic concentration at certain places was found to be many folds more than the WHO recommended limits. The treatment of arsenic contaminated water samples with kimberlite tailings showed 90-94% removal in 12 hours. The present study can be used as a basis for designing and developing filter columns, which can be attached to the tube wells for low cost and effective removal of arsenic.

Elliott County Kimberlite Elliott County Kimberlite The Elliott County Kimberlite (Sometimes called the Ison Creek Kimberlite) was discovered in Elliott County, Kentucky, by Albert R. Crandall in 1884 over two years before Carvill Lewis named a similar porphyritic peridotite occurring near Kimberley, South Africa, a kimberlite. It occurs as three separate elongate intrusive bodies 1/4 to 1/2 mi in length and a few hundred feet in width, within an area of about a square mile. The rock is a dark-green peridotite (kimberlite) composed of serpentinized olivine and a number of accessory minerals, including phlogopite, pyrope, calcite, enstatite, magnesian ilmenite, and others. Xenoliths, mainly
