Water plays an important role for existence of all kingdoms. The demand of water is   increasing for drinking, irrigation and industrial purposes due to increase in the population. Palus is located on the bank of river Krishna and it is also known for grapes, sugarcane producing land with industrial zone. Due to agricultural waste, excess use of fertilizers and anthropogenic activities, the drainage discharge, poor sanitation causes the deterioration of the ground water. The objective of this research was to study the water quality for existence of metals in ground water of industrial area. Eight different water samples were collected and analyzed. The pH of the water samples is from 6.30 to 7.70.  The parameter TDS ranges from 600.85 to 680.30 mg/L is found to be above the normal range due to deposition of solid waste.   Alkalinity is ranged from 185 to 245 which is within normal range. The BOD and COD limits in between 1.50 to 7.10 and 8.30 to 31.40 mg/L respectively. The DO is from 2.056 to 4.05. The Calcium was found to be 27.50 to 80.30 mg/L, The Chloride content is from40.50 to 99.60 mg/L. Electrical Conductivity is in between 510.00 to 1030.38 umhos/cm. Hardness of the sample under study is from 130.50 to 320.48. The magnesium is in between 11.00 to 49.00 mg/L. The Sodium and Sulphate is in between 20.36 to 70.10 and 55.90 to 140.56 mg/L respectively. The Iron, Manganese, Cobalt, Lead and Antimony were analyzed using atomic absorption spectrophotometer. The metal Iron ranges from1.0230 to 1.0960 mg/L. The excess amount of iron is due to ten different foundries.  The Cobalt is in the just above the normal range that is from 0.5060 to 0.6390 mg/L. The Manganese is in between the 0.1630 to 0.1925 mg/L but within tolerable limit. From the study it is concluded that, all water samples have parameters within normal rang except metal Iron and TDS as prescribed by world health Organization and environmental protection agency limit.
