The present study was conducted in a part of West Tripura, northeast India, to investigate the presence and sources of trace metals in groundwater and the risk to human health due to direct ingestion of groundwater. Samples were collected from 68 locations twice a year from 2016 to 2018. Mixed Ca–Mg–HCO3, Ca–Cl and Ca–Mg–Cl were the main groundwater types. Hydrogeochemical methods showed groundwater mineralization due to (1) carbonate dissolution, (2) silicate weathering, (3) cation exchange processes and (4) anthropogenic sources. Occurrence of faecal coliforms increased in groundwater after monsoons. Nitrate and microbial contamination from wastewater infiltration were apparent. Iron, manganese, lead, cadmium and arsenic were above the drinking water limits prescribed by the Bureau of Indian Standards. Water quality in...

Ground water as well as the stream water is the main source of drinking water in rural area of Chawmanu R.D. Block, Tripura, India. In the present study water is collected from different locations of 3 Gaon Panchayat of the said area. Physicochemical parameters are analysed in March, 2014. Results of the study reveals the fact that the water sources are very much polluted and is not suitable for drinking. Almost in all of the locations, Turbidity (TU), BOD, COD and iron value is found above the standard limit according to BIS. To overcome such problems Government authority as well as other public organization should come forward to cope up this problem and provided safe drinking water for the rural residents of Tripura state particularly at Chawmanu.
