Abstract :
This study described the assessment of
groundwater quality using a water quality index
(W.Q.I.) and non-carcinogenic health risk due to Nitrate
in groundwater from rural habitats of Nellikal
watershed of Nalgonda district. Groundwater samples
are collected andmeasuredfor pH, E.C., T.D.S., T.H.,and
major anions and cations.Results revealed that T.D.S.,
HCO3- and NO3 concentrations are beyond the WHO
permissible limits among the various parameters
determined. The groundwater of the study area falls in
poor water quality accounts for 35% of samples, and
5.9% of samples are inthe very poor category, according
to W.Q.I. The risk assessment demonstrated that
hazardous quotient (H.Q.) values are in the range of
0.01-105.70; 0.01-99.10; 0.01-37.75 concerning infants,
children and adults, respectively. These data
demonstrated that most of the samples (71% ) showed
HQ>1 together for infants and children suggests a severe
health effect on infants and children due to groundwater
ingestion from the Nellikal watershed. This investigation
recommended that water has to treated before supply for
drinking in the study region.
