GROUNDWATER SALINITY OF KARHA RIVER BASIN AREA, INDIA | Journal of Global Ecology and Environment

The Karha River basin contains saline groundwater. For the residents of the River area, groundwater is one of the most important resources for household and agricultural purposes. The groundwater physicochemical properties are reported in the material and procedure. These findings are used to determine the salinity of groundwater. Groundwater samples were obtained during the post-monsoon (POM) winter 2014 and pre-monsoon (PRM) summer 2015 seasons in the study area. pH, electrical conductivity, Ca2+, Mg2+, Na+, K+, total dissolved solids (TDS), total hardness (TH), HCO3-, Cl-, and SO42- were all determined using APHA's standard techniques. The findings were compared to the Indian Standard Institute's (BIS) and World Health Organization's (WHO) drinking water quality standards (WHO). The appropriateness of groundwater for agricultural applications was determined by comparing groundwater data to an FAO standard parameter.

The studied data was provided in tabular form, and the results were described using a graphical presentation. During the study period, the average yearly values of groundwater electrical conductivity ranged from 504 to 8624 S/cm. The salinity of groundwater in the Karha River basin was high. 24 percent of the samples had an EC of up to 750 S/cm, which is low salinity and appropriate for drinking, residential, and agricultural use. Groundwater samples from the rest of the area revealed high to extremely high salinity (EC > 2250 S/cm) in 76 percent of cases. Higher saline water is unfit for drinking, home use, or agriculture. The percentages of soluble sodium ranged from 7.68 to 92.83 percent. 18% of groundwater samples from the study area had a higher soluble salt percentage (>60%), indicating that the groundwater in the study area was suspect to unfit for irrigation.
