Figure 4: Exposure pathways from disused sheep-dip sites

Text description

Exposure pathways from contaminated soil:

• Direct ingestion of soil by children
• Uptake by grazing animals
• Uptake into and deposition onto food crops

Exposure pathways from contaminated groundwater:

• Uptake into food crops
• Contamination of drinking water supplies
• Irrigation onto food crops

Exposure pathways from contaminated surface water:

• Impact on aquatic species
• Contamination of drinking water supplies
• Irrigation onto food crops

Secondary exposure pathways for people:

• Consumption of drinking water, animal product and food crops

Movement of contaminants:

• Erosion into surface water, leaching into groundwater, and re-deposition onto soil.
