Abstract A hydro-environmental assessment has been
performed for Hirakud command area (India) in terms of
quantity and physicochemical quality analysis of groundwater.
Quantity analysis has been performed in terms of
water level variation and groundwater potential zone
identification. Groundwater table fluctuation analysis
reveals that water level is declining rapidly due to insufficient
recharge owing to frequent recession of monsoon
and excessive pumping of groundwater. Inefficient distribution
of canal water especially in the tail end of the
Hirakud command is accentuating the high dependency on
ground water. The groundwater potential zone index map is
generated using analytic hierarchy process along with different
influencing features, e.g., land use/cover, soil type,
geology. Three zones have been identified for Hirakud
command area (poor: 21.15 %, moderate: 46.32 %, and
good: 32.53 %). Physical and chemical parameters of
groundwater, e.g., electrical conductivity, pH, total dissolved
solids, total hardness, nitrate, iron, sodium, potassium,
calcium, magnesium, chlorine, bicarbonate and
fluoride are analyzed for the study area. Piper analysis is
used to identify dominant hydrochemical facies. United
States Salinity Laboratory and Wilcox Diagram are used to
determine the irrigation water quality. Principal component
analysis is utilized to find out key groundwater quality
parameters. The chemical analysis shows that values of all
parameters are within permissible limit. However, nitrate,
iron and fluoride are found above permissible limit in some
areas. The assessment reveals the state of the aquifer in
terms of quantity and quality.
