Arsenic contaminated groundwater Raw sequence reads. groundwater metagenome

has been creating severe health problems throughout the world. Bengal Delta Plain (BDP) covering large areas of Bangladesh and West Bengal (India), is considered the worst affected sites. More than 40 million people of this region are exposed to drinking water containing >10 µgL_1 As. Though microorganism play a critical role in As mobilization, microbial community structure within the As contaminated groundwater is not well documented. Therefore in this study we have explored the community structure in As contaminated sites of West Bengal
