what statement is true about the potential environmental impact on local water by both surface and underground mining

Answer 1

Both surface and underground mining can have significant environmental impacts on local water resources. Surface mining can cause erosion and sedimentation, which can lead to increased turbidity and sedimentation in nearby streams and rivers. It can also result in the release of toxic chemicals and heavy metals into the water, which can harm aquatic life and pose a risk to human health.

Underground mining can also have an impact on local water resources. It can cause subsidence, which can alter the flow of groundwater and surface water. It can also result in the release of contaminants into the water, particularly if the mining involves the use of chemicals or explosives.

Overall, the potential environmental impact on local water by both surface and underground mining depends on a variety of factors, including the type of mining, the location, and the specific environmental conditions of the area.
