Supplementary file 1_Characterization of crystalline basement and carbonate aquifers, Sout

Aniekan Edet's study provides data from 6 vertical electrical sounding surveys and 32 water samples collected during wet and dry seasons in southeastern Nigeria. The dataset includes physicochemical parameters, heavy metal concentrations, and derived aquifer properties from two geological areas. It was last updated on 2026-05-21 and is shared under a CC-BY-4.0 license.

Use Cases

• Compare aquifer properties like transmissivity and hydraulic conductivity between granitic basement and carbonate rock areas.
• Assess seasonal variations in water quality and heavy metal concentrations against maximum admissible limits.
• Identify geochemical processes controlling water chemistry using cation/anion ratios and hydrochemical facies.
• Evaluate human health risks from groundwater using non-carcinogenic and carcinogenic risk assessment methods.
• Model correlations between water quality parameters like TDS, EC, and hardness using multivariate statistical analysis.

Strengths

• Includes data from 32 water samples and 6 geoelectrical surveys, providing a multi-method foundation.
• Covers both wet and dry seasons, allowing for analysis of temporal variation.
• Analysis incorporates multiple indices: Water Quality Index, irrigation indices, and multivariate statistical modeling.

Limitations

• The dataset is small at 91.2 KB, suggesting limited scope or summary-level data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
