Abstract
The present research work pertains to the Gadilam river basin groundwater quality for irrigation uses with respect to the Archaean formation, the Quaternary formation, the Tertiary formation and the Cretaceous formation. Experiments were carried out for two seasons (rainy season and summer season) for two successive years (November 2018 and June 2019). Overall, 120 groundwater samples were collected from the Gadilam river basin, excluding the reserved forest area. The 50 samples were collected from the Archaean formation, 34 samples from the Quaternary formation, and 35 samples from the Tertiary Formation. The remaining sample is from the Cretaceous formation. Based on the obtained analysed data, the following agricultural water quality parameters were calculated using the following expressions: The irrigational quality parameters are used, such as sodium percentage (Na%), sodium adsorption ratio (SAR), Kelly’s ratio (KR), permeability index (PI), magnesium ratio (MR), residual sodium carbonate (RSC), and potential salinity (PS) are calculated and assessed for irrigation purposes.
Highlights
Groundwater is one of the primary resources available on earth
The percentage of sodium values are calculated in the ranges of 34.44% to 68.91% and 43.76 to 68.01% in the Archaean
Quaternary formation was observed with a Na% range of 32.59 to 82.75% and 40.55 to 80.82%
Summary
Groundwater is one of the primary resources available on earth. Groundwater is essential for drinking, domestic, agricultural and other activities in the daily lives of humankind. Groundwater is constituted of various dissolved minerals, some of which are useful for the soil and plants, whereas some may pose a threat to them [1,2]. The agricultural sector is by far the biggest user of freshwater. In Asian countries, an estimated 85–90% of all fresh water used is for agriculture [3]. Intl J Civl, Env, Agri Engg, 10-26 / 10
