What type of water occurrence can granite provide?

Granite is an igneous rock characterized by its crystalline structure and generally low porosity. The primary way that granite can provide water is through its joints and fractures. These are natural openings that occur when the rock expands and contracts due to temperature changes or when geological forces apply stress. Water can seep into these fractures, enabling it to be stored and flow within the granite formation.

While granite itself has a very low porosity, which means it does not have extensive pore spaces for water to occupy, the fractures allow for some degree of water movement and storage. This characteristic is particularly important for water well contractors, as they often rely on these joints to access groundwater. Other options, such as obtaining water through layers or on the surface, do not accurately represent how granite typically behaves in terms of water occurrence.
