Leaching to groundwater

The risk of pesticide leaching to groundwater depends on several factors. Soil condition, climate, pesticide properties, dosage, and cultivated crops are a few examples.

The simulation model MACRO and Swedish scenarios, is used in assessing the risk of leaching to groundwater for Swedish conditions. The MACRO model has been developed at the Swedish University of Agricultural Sciences (SLU).

This model can be downloaded from the FOCUS website (Forum for the co-ordination of pesticide fate models and their use).

Applying the model requires data on weather, soil and crops. These data can be ordered from SMHI (The Swedish Meterological and Hydrological Institute) at a cost of 4750 SEK.

Order for weather data

Please, place an order for data on weather conditions and crops to The Swedish Meteorological and Hydrological Institute, SMHI.

Pesticides in the environment

To learn more about fate and behavior of pesticides in the environment, you can find information on the CKB website (Centre for Chemical Pesticides).

You can read more about the risk assessment of leaching to ground water in Sweden in the following guidance documents:
