The ground water quality of Sindri township area has been studied with respect to twenty six physic-chemical characteristics. Out of twenty six characters, 07 nos. have been selected for graphical & statistical method for interpretation of the findings. The variation in water quality have been quantified by the both methods. The concept dataliers, Exceeding factor (EF) and Surrogate Number Level Exposure Factor (SNELF) have also been used for interpretation of results. Iron with EF value equivalent to 2.497and SNELF value equivalent to 2.14 appeared abnormally high. Among the seven parameters under detail study, the mean values of TDS, Total Alkalinity, Total Hardness and Iron have been found beyond the desirable limit of drinking water standard BIS:10500. Out of 14 ground water sample under study, 09 nos. of samples for water quality parameters for Total Dissolve Solid (TDS) and Total Hardness (TH), 13 nos. of samples for Total Alkalinity (TA) and 11 nos. of samples for Iron have been found to violet the desirable norms of drinking water standard.

Key words: Skewness, Kurtosis, Data outliers, Exceeding Factor, Surrogate Number Level Exposure Factor etc.
