Assessment of groundwater quality for irrigation use: a peninsular case study

Abstract

The grade of irrigation water available to irrigators has a significant impact on crops as well as yields. Therefore, it is a need to better understand irrigation water quality. The present study mainly focuses on the assessment of the suitability of water of forty-four fixed bore wells of Kanchipuram district, Tamil Nadu, India. The groundwater sample datasets of post-monsoon (2005-2013) and pre-monsoon (2006-2013) season were collected for 9 years. Water quality indices, namely sodium adsorption ratio, exchangeable sodium percent (SSP or %Na), residual sodium carbonate (RSC or RA), Kelly's ratio, permeability index, chloroalkaline indices (CAI1 and CAI2), potential salinity (PS), magnesium hazard, total dissolved solids and total hardness, have been calculated for separate bore wells. The r 1 and r 2 indices show that groundwater of the study area is Na +-SO 4 2− and deep meteoric percolation type. Majority of the wells are fall under moderate to unsuitable category of water for irrigation purposes. Further, wells water has also been classified on the base of meteoric genesis index.

Evaluation of Groundwater Quality for Suitability of Irrigation Purposes: A Case Study in the Udham Singh Nagar, Uttarakhand

“…. On the basis of PI values, groundwater quality can be assessed for its suitability for irrigation purpose [48]. According to Singh et al, the concentration of Ca 2+ , Na + , Mg 2+ , and HCO 3 − influences permeability of soil profile [49].…”

Combining Hydrogeochemical Characterization and a Hyperspectral Reflectance Tool for Assessing Quality and Suitability of Two Groundwater Resources for Irrigation in Egypt

“…Generally, the water quality index (WQI), which was initially proposed by Brown et al [3] and is based on the primary parameters of water quality, namely major cations and ions, heavy metals, temperature, and pH, is frequently used to classify the quality of water for drinking purposes. While, the irrigation water quality indicators (IWQIs), namely percentage sodium (%Na), sodium absorption ratio (SAR), soluble sodium percentage (SSP), total dissolved solids (TDS), potential salinity (PS), total hardness, and Kelly's index (KI), which are based on the major cations (K + , Ca 2+ , and Mg 2+ ) and ions (Na + , Cl − , and SO 4 2− ), are frequently used to assess the suitability of water for irrigation purposes [4][5][6][7][8]. When the values of WQI and IWQIs are outside of standard requirements, there are direct and indirect negative effects on soil characteristics and plant growth, which ultimately results in significant reductions in crop production without contributing to solve the water shortage problems in the agriculture sector.…”

Pectin—Extraction from underground stem of banana and its structural, rheological, and textural analyses and grading

“…Ash content gives an estimate of the purity of the pectin extracted—lower ash content indicates high purity. Higher ash content of banana pectin might be due to the higher mineral content of the soil in which the plants were cultivated, irrigated with water from deep bore wells, rich in minerals (Rawat et al., 2018). Ash content below 10% is reported to be good for gel formation (Maskey et al., 2018).…”
