| Short description: |
A review of literature and Danish monitoring data (GRUMO, LOOP) concerning pesticide pollution from farms and machinery parks reveals that there are a large number of point sources in Denmark. Despite concerns for Danish drinking water resources, many of these point sources are insignificant and pose no direct threat.
|
| Long description: |
Handling practices on farms were investigated and detailed investigations at 5 different sites (farm yards) were carried out. The most important risk factor for water resources is the amount of pesticides spilled, which in turn is dependant on the disposal of residual pesticides left over in the sprayer and use of rinsing tanks. The layout and cover layers at the machine parks where sprayers are filled, emptied and cleaned is also an important factor. Up to 80% of the machine parks in Denmark are without storage tanks, and spilled pesticides will leach to the ground water or nearby recipients. Despite the fact that many of the investigated sites are heavily polluted with pesticides, the source strength is typically between 1 - 300 grams active pesticide. Large reductions in the concentrations of pesticides are however observed 20 – 70 m downstream hot spots. This indicates that pesticide point sources will only pose a threat if situated close to a pumping well. The conclusion of the project is that future investigations of pesticide point sources should focus on potential point sources with a history of extensive handling of pesticides and on sites situated close to drinking water wells.
