Groundwater Hardness and Scaling Potential at Haramaya University, Ethiopia

Eight borehole samples from Haramaya University were analyzed for hardness-causing parameters and scaling potential. Concentrations of Ca2+, Mg2+, HCO3, Cl-, and SO42- were measured, with total hardness exceeding 300 mg/L CaCO3. The dataset, authored by Nagara Wakgari Futasa and last updated in June 2026, applies the TOPSIS method to select Reverse Osmosis as the suitable centralized softening technology.

Use Cases

• Evaluating water softening technology alternatives based on treatment potential and feasibility criteria mentioned in the description.
• Analyzing scaling and corrosion potential in groundwater based on indices like LSI, AI, LS, and RSI.
• Characterizing groundwater hardness types and concentrations of specific ions like Ca2+, Mg2+, and HCO3-.
• Applying multi-criteria decision analysis (TOPSIS) for environmental technology selection.

Strengths

• Specific concentration ranges are provided for key ions (e.g., Ca2+ 75-107 mg/L).
• Analysis includes multiple standard indices (LSI, AI, LS, RSI) for scaling and corrosion.
• The dataset is small (5.5 KB) and focused on a specific, described case study.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's scope is limited to eight boreholes at a single university.
