Groundwater Quality. Tamil Nadu, Dharmapuri District, Domestic and Water quality for irrigation purposes to assess water quality survey has been carried out. PH, TDS, TH, Calcium, Magnesium, Chloride, Sulphate. This paper notes that increasing levels of water pollution, the resulting billion-dollar utility and with control schemes, it provides a way to measure and evaluate the quality of given water body Development of water quality codes is necessary. The data output of current water monitoring stations is huge and Dimensional reporting units are different and Not integrated in a straightforward algebraic way, even by scientifically trained users have few means of integrating the data to provide; water quality. That quality is locally better than hook and line to be broadly defined, Because of the importance of downstream streams less emphasized in that context. Ground water by comparing the measured concentration of ions and other parameters with the suggested limits provided by the Bureau of Indian Standards, the acceptability of the groundwater in this area as drinking water was determined lists the quantity and percentage of samples that exceeded the drinking quality criteria suggested by. The quantities of PH, TDS, TH, calcium, chloride, sulphate, and nitrate as well as total hardness were consistently within suggested levels in the 652 groundwater samples that were collected and analyzed water quality for drinking. MCDM difficulties include many incompatible and conflicting criteria, different measurement units in the criteria, and the existence of completely different alternatives. These decision problems describing multidimensional situations are solved by various MCDM methods. In the WASPAS method, a composite criterion is optimally two based on the criteria sought. The first criterion of optimality via a weighted average success criterion is the WSM method, which is based on the decision criteria used to evaluate the accepted MCDM approach alternatives, such as the popular one. Weighted Aggregate Product Assessment (WASPAS) this method is an effective MCDM tool when solving eight production decision problems, namely grinding level, material depletion. From the result it is seen that Karimangalam Taluk is showing the highest value for Pennagaram Taluk is showing the lowest value. Resulting in Karimangalam Taluk ranked first; there Pennagaram Taluk has low rank.
