ABSTRACT

This study aimed to assess the impacts of industrial activities in Ogun State, Nigeria. A total of 96 samples were collected both in dry and wet seasons for analysis of physicochemical quality indicators. Hydrochemical assessment were carried out according to APHA standard while hydrochemical facies of groundwater samples was evaluated using Piper Trilinear software. Pearson correlation was applied in order to determine the relationship between two parameters. The pH at Otta in wet season ranges from 6.67 ± 0.06 to 9.42 ± 0.11; dry season ranges from 4.35 ± 0.21 to 5.70 ± 0.14 while in Sagamu (wet season) values ranges from 6.01 ± 0.04 to 6.67 ± 0.06 while those of dry season ranged from 5.15 ± 0.07 to 6.55 ± 0.07. Interpretation of piper diagram revealed no specific dominant facie at Shagamu while most samples at Otta are characterized by the dominance of (Na+, K+) water types.

摘要

这项研究旨在评估工业活动对尼日利亚奥贡州的影响。在干燥和潮湿的季节共收集了96个样品，用于分析理化质量指标。根据APHA标准进行水化学评估，同时使用Piper Trilinear软件评估地下水样品的水化学相。应用Pearson相关性以确定两个参数之间的关系。雨季在渥太华的pH值为6.67±0.06至9.42±0.11；干旱季节的数值范围为4.35±0.21至5.70±0.14，而在Sagamu（潮湿季节）的数值范围为6.01±0.04至6.67±0.06，而干旱季节的数值范围为5.15±0.07至6.55±0.07。
