Historical Water Quality Monitoring Data for Colombia, 2005-Present

160 monitoring stations form the Water Quality Reference Network, with data collected from 2005 to the present. The dataset consolidates results from physicochemical and microbiological analyses of water and sediment matrices. Records include location, date, observed property, and result, with notes on quantification limits.

Use Cases

• Analyze temporal trends in water quality parameters like RESULTADO and PROPIEDAD OBSERVADA across different DEPARTAMENTOs.
• Map pollution sources by correlating RESULTADO values with geographic features like ZONA HIDROGRÁFICA, LATITUD, and LONGITUD.
• Compare water quality metrics (PROPIEDAD OBSERVADA, UNIDAD DEL RESULTADO) across different water bodies (CORRIENTE) and elevations (ELEVACIÓN).

Strengths

• Data spans from 2005 to the present, providing a long-term view.
• Covers 160 monitoring stations across Colombia, as stated in the description.
• Includes detailed geospatial columns (LATITUD, LONGITUD, MUNICIPIO, DEPARTAMENTO) for location-based analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Some results are reported below the method's quantification limit (marked with '<'), requiring careful interpretation.
• Description metadata is limited; actual data quality requires manual inspection after download.
