“…Biannual reviews on water analysis and ECs in the journal Analytical Chemistry are a telling record of how access to new methodologies has been instrumental in bringing new contaminants to the radar. As exemplified in Fishman and Erdmann, 580 water analysis in the early 1970s was dominated by spectroscopy, electrochemistry, MS, thin layer, and GC and focused on inorganic species, petroleum hydrocarbons, and persistent organochlorides. Twenty years later, a broader suite of organic compounds had become accessible by dedicated sample extraction, HPLC, GC-MS, and the advent of biochemical methods.…”

“…The groundwater samples were analyzed with the assistance of a chemist in the laboratory. The methods and reagents used were based on the description of water analysis procedures (Fishman and Erdmann, 1973). CO3 -, Cl -, HCO3 -, Ca 2+ , and Mg 2+ were determined by titration.…”

Irrigation is vital for food security, but climate change and pollution threaten it. Thus, regular evaluations of groundwater quality for irrigation are needed. This study collected and analyzed thirty-five (35) groundwater samples from boreholes in the Southern Anambra Basin, covering the Ameki and Ogwashi-Asaba Formations. Six irrigation quality indices, including Kelly's Ratio (KR), Sodium Adsorption Ratio (SAR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC), Magnesium Adsorption Ratio (MAR), and Permeability Index (PI), were calculated to evaluate the area's irrigation suitability. Doneen PI, USSL, and Wilcox diagrams were also employed in evaluating irrigation suitability. The pH, EC, and TDS of the groundwater samples ranged from 6.6 to 8.4, 13 to 889 µS/cm, and 15.6 to 557.9 mg/L, respectively. The concentrations of HCO3 -, SO4 2-, Cl -, Ca 2+ , Mg 2+ , Na + , and K + ranged from 24 to 580, 1 to 20, 0.4 to 92.5, 10 to 74, 0.09 to 49.50, 2.26 to 30, and 0.67 to 10.0 mg/L, respectively. In general, the physicochemical parameters meet the WHO guidelines for drinking. The range values of KR, SAR, SSP, RSC, MAR, and PI were 0.019-1.712 mmol/L, 0.067-2.113, 1.86-63.13%, -5.36-7.80 mmol/L, 0.00-3.79, and 15.82-547.10%, respectively. All samples had suitable SAR and MAR values for irrigation, while 97.14%, 94.29%, 80%, and 77.14% had suitable SSP, KR, RSC, and PI, respectively. This study has demonstrated that groundwater within the study area is suitable for drinking and irrigation, however, it is essential for periodic assessment as anthropogenic activities continue to increase in the area.
