Clean and safe potable water is the basic necessity for sustenance of healthy human life. Ground  water considered to be the safest among various sources of water, ironically, has been polluted  with variety of contaminants. In the present preliminary assessment, an attempt was made to  verify the drinking water quality of samples collected from Chetak Vihar colony, Jamdoli, Jaipur.  Parameters studied includes gross sensory examination and biochemical attributes of water like  pH, chloride, total hardness, fluoride, nitrate, iron, and residual (free) chlorine contents present in  the samples. The parameters were compared with the Indian Standard Specifications for drinking  water (IS10500-1983). All the parameters evaluated were in the prescribed limit except, for total  hardness, and nitrate contents of one sample. The values of total hardness and nitrate content  were comparatively higher in one of the samples i. e. 625 mg/L, and 100 mg/L, respectively.  The increased total hardness and nitrate content above the recommended level may leads to  severe health complications in humans and animals and is a matter of great concern from the  public health point of view. Therefore, we suggest regular screening of drinking water samples  particularly for possible contaminants with a need to take appropriate measures to safeguard  human and animal health.
