Protecting
Surface Water

Do not apply acetochlor under conditions which favor runoff or wind erosion of soil to non-target areas. To prevent off-site movement due to runoff or wind erosion:

• Avoid treating powdery dry or light sandy soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation.
• Do not apply to impervious substrates such as paved or highly compacted surfaces or frozen or snow covered soils.

Factors that affect the amount of surface water contamination include:

• amount of precipitation or irrigation
• erodability of land (slope, etc.)
• location of surface water
• type of tillage system

Reducing soil erosion, properly timed applications, and using common sense in selecting the site of application helps protect surface water. The ARP supports and promotes the use of Best Management Practices (BMP's) for the protection of ground and surface water.
