Cotton is produced around Point Pedro in the fertile calcic red latosol soils . The eastern coast of Point Pedro forms a 3 mile wide , 20 mile long beach with sand dunes up to 100 feet high , extending to Thalayady . The porous soil has a water table deep underground with an estimated one billion litres of fresh water . The Boxing Day tsunami of 2004 raised the salt content of the ground water .
