Which property of a pesticide would make it more likely to move with water in surface runoff?
- A.
  
  High solubility
- B.
  
  High adsorption
- C.
  
  High volatility
Correct Answer
A. High solubility

Explanation
A pesticide with high solubility would be more likely to move with water in surface runoff. Solubility refers to the ability of a substance to dissolve in a liquid, and in this case, a pesticide that is highly soluble would easily dissolve in water. As a result, when water flows over the surface of the land, it would carry the pesticide along with it, increasing the likelihood of the pesticide being transported through runoff.

Which statement is true about groundwater or surface water contaminated by pesticides?
- A.
  
  Pesticides cannot reach groundwater by runoff
- B.
  
  Runoff and erosion are sources of surface water contamination by pesticides
- C.
  
  Pesticide contaminated surface water will not reach groundwater
Correct Answer
B. Runoff and erosion are sources of surface water contamination by pesticides

Explanation
Runoff and erosion are sources of surface water contamination by pesticides. When pesticides are applied to crops or other areas, they can be carried away by rainwater or irrigation runoff, which then flows into nearby surface water bodies such as rivers, lakes, or streams. Similarly, erosion can transport pesticides from treated areas to surface water through the movement of soil particles. This contamination poses a risk to aquatic organisms and can also potentially affect the quality of drinking water sources if they are connected to the contaminated surface water.

Which is an example of non-point-source contamination of groundwater?
- A.
  
  Leaching from a pesticide mixing area
- B.
  
  Pesticides that dissolve and leach through soil after it rains
- C.
  
  Dumping leftover pesticide products down a well
Correct Answer
B. Pesticides that dissolve and leach through soil after it rains

Explanation
Pesticides that dissolve and leach through soil after it rains is an example of non-point-source contamination of groundwater. In this scenario, the pesticides are applied to the soil and when it rains, the water carries the dissolved pesticides deeper into the ground, eventually reaching the groundwater. This type of contamination is considered non-point-source because it does not originate from a specific, identifiable location. Instead, it occurs over a larger area and is a result of various sources contributing to the contamination.

Under what soil conditions are pesticides more likely to leach through the soil?
- A.
  
  A heavy clay soil, low in organic matter, where groundwater is shallow
- B.
  
  A sandy soil, high in organic matter, where groundwater is deep
- C.
  
  A sandy soil, low in organic matter, where groundwater is shallow
Correct Answer
C. A sandy soil, low in organic matter, where groundwater is shallow

Explanation
Pesticides are more likely to leach through the soil in a sandy soil because sandy soils have larger pore spaces and less ability to retain water and chemicals. Additionally, low organic matter content reduces the soil's ability to retain and bind pesticides, making them more prone to leaching. Shallow groundwater further increases the likelihood of leaching as it provides a pathway for the pesticides to move downwards through the soil profile.

  Use terrace and conservation tillage practices
- C.
  
  Clean sprayers near sinkholes
Correct Answer
B. Use terrace and conservation tillage practices

Explanation
Terrace and conservation tillage practices are recommended best management practices for preventing contamination of surface and groundwater by pesticides. Terrace practices involve creating terraces or ridges along the slopes of fields to prevent runoff and erosion, thereby reducing the risk of pesticides reaching water bodies. Conservation tillage practices involve minimizing soil disturbance during planting and cultivation, which helps to retain organic matter and reduce erosion. By adopting these practices, the movement of pesticides into surface and groundwater can be significantly reduced, protecting the quality of these water sources.
