Assessment of groundwater pollution risk is purposed to be of particular value for environmental management programs development, this research estimated and calculated of groundwater pollution risk potential in Yogyakarta City using DRASTIC Model, DRASTIC parameters developed as Depth to water (D), net Recharge (R), Aquifer media (A), Soil media (S), Topography (T), Impact of vadose zone (I), and Hydraulic conductivity (C), the weights and ratings assigned in this research were similar to the typical ratings suggested in the original Methode. The result final assessment that groundwater pollution risk potential are classifies 4, 27% of the area as having very low, 15, 12% of the area as having low, 20, 17 % as having moderate, 43, 10% as having high, and 17, 34% as having very high. The model was validated using E. Coli parameters as a represent of pollution risk where the results having exceeds 85% of total samples that a value exceeds from the standard of quality > 0 MPN/100 ml. However, this research is a preliminary to be continued in the further research.
