Suitability Assessment of Groundwater for Drinking and Irrigation Use in Palacode Area of Dharmapuri District, Tamil Nadu

摘要

The study comprised suitability assessment of groundwater for drinking, irrigation and livestock use. Groundwater samples from selected bore wells. A total of 25 groundwater samples were collected at different locations from Palacode area of Dharmapuri district, Tamil Nadu, were analyzed for important physio-chemical attributes by adopting APHA standard methods. Physio-chemical characterization of the samples revealed that ground-water from most of the sources was not fit for drinking owing to a high concentration of hardness, fluoride, nitrate and chloride. Irrigation water classified based on SAR and RSC alone indicate that the water samples belong to good category. Graphical representation of the chemical data on the irrigation suitability diagram shows that most of water samples are moderate water except few samples falls in poor water. It is inferred from the study that these water sources was not fit for drinking and cooking but with certain affordable ameliorations at household level it could be made fit for other domestic purposes, such as bathing, washing and gardening. The high concentration of the chemical constituents is attributed to the lithologic composition of the area.
