Groundwater quality in the Upper Santa Ana Watershed study unit, California

Abstract

Groundwater provides more than 40 percent of California's drinking water. To protect this vital resource, the State of California created the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The Priority Basin Project of the GAMA Program provides a comprehensive assessment of the State's groundwater quality and increases public access to groundwater-quality information. The Upper Santa Ana Watershed is one of the study units being evaluated.

Introduction The Earth changes continuously in response to natural processes and human activity. The collection and interpretation of time-series imagery enhances our ability to observe and monitor Earth’s dynamic processes as well as study and understand the rapidly changing surface of our planet. The Global Fiducials Library (GFL) provides repeated satellite imagery of selected locations around the world to help scientists observe, document, and better understand those changes over time.
