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 a well-documented impact of both surface and underground mining activities, which can result in the contamination of local water sources due to the exposure of sulfide minerals to oxygen and water, leading to acid mine drainage.
