✔✔ALL.. mixing, loading, applying, equipment cleaning, storage, transportation, and spill cleanup.

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.
n n n n n n n n n n n n n n n n n




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.
n




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.
n n n n n n




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.
n n n n n n n n




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.
n n n n n n n n n n n n n n




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.
