Saline groundwater occurs in the Karha
River basin area. Groundwater is one of the major resource for the peoples of
River area for domestic and agricultural purpose. The groundwater samples from
study area were collected in the period of post-monsoon (POM) and pre-monsoon
(PRM) seasons. The various physico-chemical parameters such as pH, Electrical conductivity,
Ca2+, Mg2+, Na+, K+, total
dissolved solids (TDS), total hardness (TH), HCO3-, Cl-,
and SO42- were determined using standard procedures of
APHA. The results of analysis were compared with the drinking water quality
standards of Indian Standard Institute (BIS) and World Health Organization
(WHO). For suitability of groundwater for agricultural purposes, groundwater
data was compared with standard parameter of FAO. The average annual values of
the electrical conductivity of groundwater ranged from 504 to 8624 μS/cm in the
study period. In Karha River basin area the salinity of groundwater was
considerable. 24% samples were EC up to 750 μS/cm which is low salinity and
suitable for all purposes such as drinking, domestic and agricultural. In rest of the area 76% groundwater samples
showed high to very salinity (EC > 2250 μS/cm). Higher saline water is not
suitable for drinking, domestic and agricultural purpose. The soluble sodium
percentage values ranged from 7.68 to 92.83%. 18% groundwater samples from the
study area showed higher soluble sodium percentage (>60%), indicating,
groundwater in the study area was doubtful to unsuitable for irrigation
purpose.
