The present study aims to identify the ground water contamination problem in villages located in the close vicinity of Municipal dumping yard at Guntur (A.P.), India. Ground water samples were collected from different villages at the depth of 40 and 120 feet from earth’s surface layer. Analytical techniques as described in the standard methods for examination of water and waste water were adopted for physico-chemical analysis of ground water samples and the results compared with the standards given by WHO and BIS guidelines for drinking water. The present investigation revealed that the water quality is moderately degraded due to high range of seven water quality parameters such as pH, Temperature (18.33-32.36 0C), Electro conductivity (1175-19500 μmho/cm),Turbidity (0.3-0.5), TDS (775-1240 mgL-1), Alkalinity (335- 385 mgL-1), Ca-Hardness (160-1640mgL-1), Mg-Hardness (130-2900 mgLÉ1), Total hardness (365-4500) Flourides (0.7- 1.5) chlorides (160-5700). The water quality index (WQI) also indicated the all the water quality rating comes under the standard marginal values (45-64), but water quality near to dumping yard could be more polluted and physic-chemical parameters should be exceed than the permissible limits and it is not suitable for drinking purposes. Here the water is frequently threatened or impaired and conditions usually depart from natural or desirable levels.
