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.

This is because both surface and underground mining operations can disturb the surrounding soil and rock, potentially exposing sulfides that, when oxidized, can produce acid mine drainage, which carries heavy metals into local water sources.
