Groundwater Hardness and Scaling Potential for Eight Boreholes in Ethiopia

Eight groundwater samples from boreholes at Haramaya University were analyzed for hardness-causing parameters. Concentrations of Ca2+, Mg2+, HCO3, Cl-, and SO42- were measured, with total hardness exceeding 300 mg/L CaCO3. The dataset, created by Nagara Wakgari Futasa and last updated in June 2026, includes indices like LSI, AI, LS, and RSI to evaluate scaling and corrosion potential.

Use Cases

• Evaluate scaling potential in water supply systems based on Langelier Saturation Index (LSI) and Ryznar Stability Index (RSI) values.
• Compare groundwater hardness characteristics across different boreholes based on concentrations of Ca2+, Mg2+, and HCO3.
• Assess the feasibility of centralized softening technologies like Reverse Osmosis based on water quality parameters.
• Model corrosion potential in piping infrastructure based on Aggressive Index (AI) and Larson–Skold Index (LS) results.

Strengths

• Specific concentration ranges are provided for key ions (e.g., Ca2+ 75-107 mg/L, Mg2+ 41-60 mg/L).
• Multiple standard indices (LSI, AI, LS, RSI) are calculated to assess water stability.
• Data is focused on a specific, real-world problem of scaling and clogging at a university water system.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope.
• Row count and column-level documentation are unknown, requiring inspection after download.
• Data is from a specific location and time, which may limit generalizability.
