Groundwater Hardness and Softening Technology Analysis for Haramaya University, Ethiopia

A 2026 study by Nagara Wakgari Futasa characterizes groundwater hardness from eight boreholes at Haramaya University in Ethiopia. The dataset includes concentrations of calcium, magnesium, bicarbonate, chloride, and sulfate, along with indices for scaling and corrosion potential. It applies the TOPSIS method to evaluate and select Reverse Osmosis as the ideal centralized softening technology.

Use Cases

• Evaluate scaling and corrosion potential in groundwater based on Langelier, Ryznar, Aggressive, and Larson–Skold indices.
• Compare concentrations of hardness-causing ions (Ca2+, Mg2+, HCO3-, Cl-, SO42-) across multiple borehole sources.
• Apply multi-criteria decision analysis (TOPSIS) for softening technology selection based on treatment potential and feasibility factors.

Strengths

• Specific ion concentration ranges are provided (e.g., Ca2+ 75–107 mg/L, Mg2+ 41–60 mg/L).
• Analysis includes four distinct water quality indices (LSI, RSI, AI, LS) for eight borehole samples.
• Clear methodology described for technology evaluation using the TOPSIS technique.

Limitations

• Dataset is very small at 5.5 KB; row count and column-level documentation are unknown.
• Geographic scope is limited to a single university campus in Ethiopia.
• Freshness should be verified; last updated date is 2026-06-02.
