Understanding groundwater Nnnmmmm mmmn Groundwater and surface water are inextricably related through the hydrologic (or water) cycle. Extracting groundwater can impact surface water resources and vice versa. Historically, groundwater and surface water have been treated as separate entities. However, in times of drought and water scarcity, understanding and managing the interconnection between groundwater and surface water has become more important
