Gateway to karst aquifer found in Tamil Nadu well

A modest open farm well in Thisayanvilai in Tirunelveli district is drawing immense attention due to its capacity to devour water even during flash floods. A team of experts from the Indian Institute of Technology - Madras (IIT-M) that studied the 'miracle well', as Ayankulam villagers call it, found that it connects to an underground karst aquifer, which helps it gobble any amount of rainwater that goes into it.
