Water
Quality
Four factors influence groundwater vulnerability to pesticide contamination:
- Chemical properties of the pesticide
- Low soil adsorption
- Persistence
- Soil Types
- Sandy or gravel texture
- Low organic matter content
- Site Characteristics
- Shallow water table
- Sinkholes
- Abandoned wells
- Management Practices
- Improper chemical storage, handling, and use
Options for protecting surface water near application sites include:
- No-spray strips around surface water supplies, wells, or irrigation
ditches
- Grass waterways and grass buffers to resist runoff
- Use of conservation practices on erodible lands
- Plow berms around sinkholes
