What Is Causing Sinkholes?
Typical activities that can lead to sinkholes are:
Decline of water levels – drought, groundwater pumping (wells, quarries, mines) Disturbance of the soil – digging through soil layers, soil removal, drilling. Point-source of water – leaking water/sewer pipes, injection of water.
What is a natural cause of a sinkhole?
The most common causes of a sinkhole are changes in groundwater levels or a sudden increase in surface water. A natural sinkhole typically occurs when acidic rainwater seeps down through the surface soil and sediment until it reaches a soluble bedrock like salt, limestone or sandstone.
