locations. All these samples are free from colour and pollutants.

Summary of Ground water:

The pH limit fixed for drinking water samples as per IS:10500 is 6.5 to 8.5.

During the study period, the pH of the groundwater was found varying between

7.2 and 7.4. The pH values for all the samples collected in the study area during

study period were found to be within the acceptable limits.

The desirable limit for total dissolved solids as per IS:10500 are 500 mg/l here as

the permissible limits in absence of alternate source is 2000 mg/l. In groundwater

samples collected from the study area, the total dissolved solids (TDS) were found

to be varying between 556mg/l and 731mg/l. The TDS of all the samples were

below the permissible limit of 2000 mg/l.

The desirable limit for Chloride is 250 mg/l as per IS:10500 where as the

permissible limit of the same is 1,000 mg/l. The Chloride levels in the

groundwater samples collected in the study area were ranging from 138 – 198

mg/l

The desirable limit as per IS:10500 for hardness are 300 mg/l where as the

permissible limit for the same is 600 mg/l. In the groundwater samples collected

from the study area, the hardness was found to be varying from 149 mg/l to

231mg/l.

Fluoride is the other important parameter, which has the desirable limit of 1 mg/l

and permissible limit of 1.5 mg/l. However, the optimum content of fluoride in the

drinking water is 0.6 to 1.5 mg/l. In the groundwater samples of study area the

fluoride values were found to be within a range of 0.44 mg/l to 0.69mg/l.
