Groundwater Quality Indicators for Saline Intrusion in Spain (2021)

2021 data on saline intrusion into coastal groundwater bodies in Spain, based on chloride analyses from national and European monitoring programs. The dataset is managed by the Executive Board of the Geographic Information Infrastructure of Spain (CODIIGE) for the Spanish SDI (IDEE). It is served via a Web Map Service (WMS) supporting multiple coordinate reference systems.

Use Cases

• Mapping areas vulnerable to saline intrusion based on chloride concentration data.
• Assessing the impact of groundwater overexploitation on water quality in coastal aquifers.
• Integrating groundwater quality indicators into broader environmental monitoring systems via WMS.

Strengths

• Data is based on official monitoring programs compliant with national and European legislation.
• The WMS service offers visualization and supports multiple coordinate reference systems (e.g., EPSG:4326, EPSG:25830).

Limitations

• Row count and specific column-level documentation are absent, limiting suitability assessment.
• The last update date is unknown, so data freshness is unverified.
• The description metadata is limited; actual data quality requires manual inspection after access.
