Ground water quality assesment of pub – nalbari block of nalbari District, Assam, India

Groundwater is one of the primary sources for drinking in Nalbari district of Assam, India. Nine water quality parameters have been considered as important indicators to evaluate water quality status in 09 tube well water samples located in the Pub Nalbari Block of Nalbari District. The parameters considered for evaluation are pH, electrical conductivity, calcium, magnesium , chloride and alkalinity. Groundwater was well within the permissible limit for the different water quality parameters. The model predicts status of groundwater quality along with measure of its sustainability. The ranking of the tube wells corresponding to drinking uses also provides clarity to the decision makers to formulate suitable policies for treatment processes and sustainable planning of groundwater resources in the region. The study reveals that the water quality is mainly influenced by natural weathering process.
