, Q1. A water resource manager is evaluating the off-site movement of a herbicide
applied to a lake for aquatic weed control. The herbicide has a soil adsorption
coefficient (Koc) of 50 mL/g and a half-life of 30 days. Which combination of factors
most increases the risk of off-site movement to groundwater?
A. High organic matter soil and low rainfall
B. Sandy soil with high permeability and shallow water table
C. Clay soil with high cation exchange capacity
D. Steep slope with heavy vegetation cover
Correct Answer: B. Sandy soil with high permeability and shallow water table
Rationale: The herbicide's low Koc indicates weak adsorption to soil, making it highly
mobile. Sandy soils with high permeability and a shallow water table facilitate rapid
percolation to groundwater. High organic matter (A) increases adsorption, clay (C) also
binds more, and heavy vegetation (D) reduces runoff.
Why Wrong:
A - High organic matter increases adsorption, reducing mobility.
C - Clay soils bind pesticides more strongly, limiting leaching.
D - Steep slopes increase runoff but vegetation reduces flow and promotes infiltration,
not necessarily groundwater contamination.
Reference: NCSU Pesticide Safety Education, 'Pesticide Properties and Environmental
Fate' (2024)
Q2. According to FIFRA and the North Carolina Pesticide Law, which of the
following is a violation for a certified applicator performing aquatic pest control?
A. Applying a pesticide at a rate lower than the label rate to protect non-target species
B. Applying a pesticide to water when the label prohibits aquatic use
C. Storing pesticides in a locked cabinet away from food
D. Keeping records of all pesticide applications for two years
Correct Answer: B. Applying a pesticide to water when the label prohibits aquatic use
Rationale: Using a pesticide in a manner inconsistent with its labeling is a violation under
FIFRA. Applying a pesticide to water when the label prohibits aquatic use is a clear
violation. Lower rates (A) are also inconsistent with label unless allowed, but the question
asks which is a violation, and B is unequivocally prohibited.
Why Wrong:
A - Applying below label rate is also a violation unless the label allows it, but it's not
as direct as B.
C - Proper storage is a requirement, not a violation.
D - Recordkeeping is a legal requirement, not a violation.
