• In Sweden farmers are legally obliged to apply to local authorities for permits for pesticide use if their land lies within a designated water abstraction zone.
• A standalone modelling tool developed by SLU (MACRO-DB) is available to facilitate risk assessment and decision-making in water abstraction zones.
• The tool, which is used both by local authorities (who make the decisions) and farmers/landowners and consultants, is based on the well-established leaching model MACRO 5.2 (Larsbo and Jarvis, 2003; Larsbo et al., 2005).

Our aim is to develop a robust meta-model of MACRO-DB, as a fast and easy-to-maintain web-based tool for these risk assessments.
