Which of the following is an environmental concern related to munitions disposal?

The concern regarding the contamination of soil and water directly relates to the disposal of munitions because improper disposal methods can lead to hazardous materials, such as heavy metals and explosive residues, leaching into the surrounding environment. This can have detrimental effects on local ecosystems, human health, and agricultural land. Contaminated soil can affect plant growth and alter the composition of the local flora, while tainted water can harm aquatic life and disrupt drinking water sources for nearby communities. Therefore, ensuring safe and responsible munitions disposal is critical to mitigating these environmental risks.

While the other options—increase in air traffic, disruption of local wildlife habitats, and noise pollution—are also valid environmental considerations associated with munitions-related activities, they do not focus specifically on the direct and severe risks posed by soil and water contamination.
