Namibia Groundwater Quality Under Low-Intensity Land Uses, 1900-2000 Boreholes

68 borehole samples from 2020 in a semi-arid savanna of Namibia, drilled between 1900 and 2000, were analyzed for water quality. The dataset, authored by Martin Hipondoka, examines the impact of low-intensity land uses including national parks, conservancies, livestock farms, and game reserves. It tracks changes in water quality relative to drilling conditions and compares dry and wet season samples.

Use Cases

• Analyzing the impact of land-use types (national park, conservancy, livestock farm, game reserve) on groundwater quality parameters.
• Tracking temporal changes in water quality (improved, deteriorated, unchanged) relative to borehole drilling conditions.
• Comparing seasonal variations in groundwater quality between dry and wet season samples.
• Evaluating the effect of local water provision practices on trough water quality relative to source groundwater.

Strengths

• 68 borehole samples provide a specific sample size for analysis.
• Data includes temporal comparison of water quality changes (44% unchanged, 40% deteriorated, 16% improved).
• Seasonal comparison shows 76% of sites maintained or improved water quality.
• Specific parameters exceeding WHO guidelines (Mg, TDS, NO3, F, Cl) are identified.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific semi-arid savanna region studied.
