How do pesticides and herbicides enter groundwater?
-
Through leaching and runoff
-
Direct application to groundwater
-
Atmospheric deposition
-
Industrial wastewater discharge
A
Correct answer
Explanation
Pesticides and herbicides primarily enter groundwater through leaching, where they are dissolved by water and carried down through the soil profile, and runoff, where they are carried away by surface water and eventually infiltrate into the ground.
Which type of pesticide is more likely to contaminate groundwater?
-
Water-soluble pesticides
-
Non-water-soluble pesticides
-
Systemic pesticides
-
Contact pesticides
A
Correct answer
Explanation
Water-soluble pesticides are more prone to leaching and runoff, increasing the risk of groundwater contamination.
Which of the following is NOT a common method for detecting pesticides and herbicides in groundwater?
-
Gas chromatography-mass spectrometry (GC-MS)
-
High-performance liquid chromatography (HPLC)
-
Immunoassay
-
Visual inspection
D
Correct answer
Explanation
Visual inspection is not a common method for detecting pesticides and herbicides in groundwater, as these chemicals are typically present at very low concentrations and require specialized analytical techniques for detection.
Which of the following is NOT a common remediation technology for groundwater contaminated by pesticides and herbicides?
-
Pump-and-treat
-
Bioremediation
-
Chemical oxidation
-
Natural attenuation
D
Correct answer
Explanation
Natural attenuation is not a common remediation technology for groundwater contaminated by pesticides and herbicides, as these chemicals are typically persistent and do not degrade naturally at a significant rate.
