Surface Water Nitrate Pollution from Agriculture in Spain (2024)

A 2024 Web Map Service from Spain's Geographic Information Infrastructure visualizes nitrate pollution in surface water attributed to intensive agricultural production. The dataset represents the most important diffuse source of this pollution as the excessive or inadequate application of nitrogen fertilizers. It is offered through multiple coordinate reference systems, including EPSG:4326 (WGS 84) and several UTM zones.

Use Cases

• Map and analyze spatial patterns of nitrate contamination based on the geospatial data layers.
• Model the impact of intensive agricultural production on water quality based on the described pollution source.
• Assess environmental policy effectiveness by tracking nitrate levels from agricultural origin over time.
• Integrate water quality indicators into regional environmental risk assessments based on the provided WMS service.

Strengths

• Data is from 2024, suggesting relatively recent measurements.
• The service supports multiple coordinate reference systems (e.g., EPSG:4326, EPSG:4258, EPSG:25829) for flexible integration.
• The dataset is explicitly focused on nitrate pollution from a specific origin (agriculture).

Limitations

• Row count and specific data values are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after accessing the service.
• Last update date is unknown; freshness beyond the 2024 reference is unverified.
