What information does a geologic log provide?

• A. A summary of water treatment methods
• B. A description of underground features found during well drilling
• C. An analysis of surface water quality
• D. A report on local weather conditions

Answer: (B)

A geologic log is a detailed record created during the drilling of a well that captures various underground features encountered as the drill penetrates through different geological layers. This log includes information such as the types of rock and soil present, their depths, and any significant geological characteristics, such as faults or water-bearing formations. By documenting these features, a geologic log serves as a valuable tool for understanding the hydrogeology of an area, which is essential for water resource management and well construction. It allows operators and geologists to assess the suitability of a site for water extraction and to make informed decisions regarding the development of groundwater resources. Understanding the underground features described in the geologic log can also help in predicting the potential yield of the well and the quality of the groundwater. In contrast, the other options relate to different aspects of water management or environmental conditions that are not captured within the geologic log itself.
