Groundwater Basics

Groundwater is an often misunderstood resource that provides drinking water to one quarter of New Yorkers, and half of all Americans. It can be found virtually everywhere on the planet at depths ranging from very shallow to very deep. Although bedrock formations are a significant source of groundwater supply, the most productive aquifers in New York are generally located in unconsolidated sediments (e.g., sand and/or gravel deposits).
