Jodhpur  is a town and district of Rajasthan  (India) Coordinates at Latitude   26° 15' 49.9068'' N-Longitude73° 0' 32.2452'' The present investigation was taken up to evaluate the heavy metal concentrations in the ground water of Industrial Area in Jodhpur Rajasthan. The concentration of six eco-toxic metals such as copper, zinc, Manganese, iron, nickel, and lead were analyzed for 39 groundwater sampling stations in the study area using atomic absorption spectrometer. The results showed that two metals ion, viz. Nickel, and lead exceeded the concentration limit of BIS (2012) in most of the water samples indicating severe human health hazard. The single-factor pollution index (Ii ) and compound pollution index (CPI) value of these two  metals were very high, i.e., much greater than 1 The other metal concentrations were found within the safe permissible ranges.Heavy metal pollution index is an effective method of rating and ascertaining the water quality with respect to heavy metals. An index value of 100 is considered to be critical, and on the basis of mean concentration, this value in the study area was observed to be 391 which is considerably higher than the stipulated critical index value. 87.17%of the groundwater samples are seen to be having an index far above the critical figure of 100.The study results revealed that both the geogenic and anthropologic activities influenced the groundwater system of the area. This study has massive relevance in designing control measures and action plans for reducing the pollutant influx into the groundwater. Prompt enforcement of environmental protection laws is needed to prevent continuous pollution of the area.
