Answer 1

The statement that is true about the potential environmental impact on local water by both surface and underground mining is: **Both types of mining can cause acid and heavy metals to get into local water.**

Both surface and underground mining operations disturb the earth and expose minerals that can lead to acid mine drainage, which results in the leaching of heavy metals into local water sources.
