Hydro-quality Analysis of Ground Potable Water in Relation to Fluoride at Barkagaon, Hazaribag, Jharkhand, India

Quality assessment was carried out at 36 sites of Barkagaon Block of Hazaribag district. With reference to three different sources of potable water (i.e. 108 samples) different water parameters analysis was done in view of fluoridation. It reveals that out of 108 samples were fluoride observed in only 9 samples, in % contribution, the fluoride level zero (0) was observed in 91.67% while more than zero (0) was confirmed in 8.33% of water sample ranging in between 0.4-6.5 mg/ L. Lowest fluoride sites was Napokhurd and highest was Gali in the Barkgaon Block. Dental fluorosis cases were also observed at the study area, as per Dean’s index. A correlative studies of different water parameters and fluoride indicated –ve relation with pH (r= -0.28), alkalinity (r=-0.21), total hardness (r= -0.02) and Calcium(r=-0.65), while +ve correlation was observed with temperature(r=+0.23) ,TDS (r=0.1) , chloride (r=0.25) and magnesium (r=0.62).
