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 can result in the leaching of heavy metals and the creation of acid mine drainage, which can severely impact local water quality. While the other statements may also hold some truth, the first statement is directly related to the well-documented environmental impacts of mining on water systems.
