The management of the subsurface and surface water
resources is important for various purposes. Since the quantity and quality of
water available for irrigation in India is variable from place to place,
groundwater quality in the Dimbhe command area was evaluated for its
suitability for domestic and irrigation purposes
by
collecting 37 dug well samples during the post monsoon period of 2014. The
suitability assessment was made by estimating pH, electrical conductivity,
total dissolved solids, and alkalinity besides major cations (Na
+, K
+,
Ca
2+, and Mg
2+) and anions (
, Cl
-,
, and
). Out
of 37 groundwater samples, 5.41% represents good water, 62.16% indicate poor
water, 29.73% indicate very poor water and 2.7% indicate water unsuitable for
domestic purposes. Based on these analyses, irrigation quality parameters like,
sodium absorption ratio, permeability index, Kelley’s ratio, soluble sodium
percentage, residual sodium carbonate, %Mg, %Na, and Mg hazard ratio were
calculated. Assessment of groundwater samples indicated that majority of them
in both the seasons are suitable for irrigation purposes.
