Why is the location of your pesticide use site the main factor in determining if you need to take special action to
n n n n n n n n n n n n n n n n n n n n n
protect endangered species or ground water. - CORRECT ANSWER✔✔only in areas where endangered
n n n n n n n n n n n n n
species live or are being introduce and in areas where ground water is likely to be contaminated.

How will you know if you must take special action to protect endangered species or ground water? - CORRECT
n n n n n n n n n n n n n n n n n n
ANSWER✔✔The labeling will tell you if there is special measures necessary, but may not contain the special
n n n n n n n n n n n n n n n n n
instructions.

What are some factors that determine whether pesticides will reach ground water? - CORRECT ANSWER✔✔
n n n n n n n n n n n n n n
presence or absence of water in the surface of the site where the pesticides are released; chemical
n n n n n n n n n n n n n n n n
characteristics of the pesticides; types of soil; location of ground water - its distance from the surface and the
n n n n n n n n n n n n n n n n n n n
type of geological formations above it.
n n n n n n
, How can you help prevent pesticides from reaching ground water? - CORRECT ANSWER✔✔follow the
n n n n n n n n n n n n n
directions; don't use more pesticide than labeling directs; avoid application methods that present a risk; keep
n n n n n n n n n n n n n n n n
pesticides from back-siphoning into your water.

Why is the amount of water on the surface of the soil at the pesticide use site an important factor in ground
n n n n n n n n n n n n n n n n n n n n n
water contamination? - CORRECT ANSWER✔✔If there is more water on the soil than the soil can hold the
n n n n n n n n n n n n n n n n n n
water and the pesticides is likely to move downward to the ground water.
n n n n n n n n n n n n n
Explain how the solubility, absorption, and persistence of a pesticide affect its ability to move into ground
n n n n n n n n n n n n n n n n
water. - CORRECT ANSWER✔✔Solubility - some pesticides dissolve easier into water and are more likely to
n n n n n n n n n n n n n n n n
move into ground water.
n n n n
Absorption - Some pesticides become tightly attached to soil particles and are not likely to move out the soil
n n n n n n n n n n n n n n n n n n
and into the water system.
n n n n n
Persistence - Some pesticides to not break down quickly and remain in environment for a long time making
n n n n n n n n n n n n n n n n n
them more likely to move into ground water.

What types of soil slow the movement of pesticides into ground water? What types permit rapid movement? -
n n n n n n n n n n n n n n n n n
CORRECT ANSWER✔✔soils that are fine textured and contain organic matter slow the downward movement
n n n n n n n n n n n n n n
of the water containing pesticides.
n n n n n n
coarse sandy soils generally allow the water to carry pesticides rapidly downward.
n n n n n n n n n n n
What geologic factors affect movement of pesticides into ground water? - CORRECT ANSWER✔✔Distance to
n n n n n n n n n n n n n
ground water, permeability of geologic layers, and the presence or absence of sink holes.

What is an endangered specie? - CORRECT ANSWER✔✔a plant or animal that is in danger of becoming
n n n n n n n n n n n n n n n n
extinct.
n
What is a habitat? - CORRECT ANSWER✔✔the area that an animal needs for survival.
