尼日利亚西南部奥杜市地表水的综合水化学评估、质量评估、矿物物种鉴定和灌溉适宜性

Key Points

• This research aims to assess the hydrochemical characteristics and water quality of surface waters in Ondo City, Nigeria.
• Twenty surface water samples were collected and analyzed for physicochemical parameters.
• Standard analytical methods and statistical tools were utilized, with saturation indices modeled using PHREEQC software.
• Geochemical processes were interpreted through hydrochemical plots and correlation analysis.
• pH levels ranged from 6.9 to 7.6, and temperatures were between 29 and 33 °C, indicating permissible limits.
• 90% of water samples were poor quality and unsuitable for drinking according to the Water Quality Index.
• Over 90% of the samples were determined to be suitable for agricultural irrigation use.
