Vulnerability of Water to Pesticide Contamination in Alluvial Aquifers, France

The Bureau de Recherches Géologiques et Minières (BRGM) provides a geospatial dataset mapping the vulnerability of subterranean waters, specifically alluvial aquifers, to contamination by plant protection products (pesticides). This dataset was created by GRAPPE Lorraine using CORPEN methodologies to assess monitoring network representativeness and guide water quality restoration actions. The data was last updated on March 27, 2019.

Use Cases

• Assess the representativeness of pesticide monitoring networks based on mapped vulnerability zones.
• Guide actions for restoring water quality in areas identified as highly vulnerable to contamination.
• Perform regional diagnosis of water contamination risks related to agricultural pesticide use.
• Support geographical information system (GIS) processing for environmental risk assessment.

Strengths

• Dataset is based on established CORPEN methodological proposals for regional diagnosis.
• Created by a specific research group (GRAPPE Lorraine) for a defined mapping purpose.
• Last update date (2019-03-27) is explicitly provided.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2019-03-27 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
