Spring flow from the south rim of Grand Canyon (fig. 1) is an important resource in Grand Canyon National Park (GCNP). Springs offer refuge to endemic and exotic terrestrial wildlife species and help maintain the riparian areas associated with this resource. Recent real estate development on the Coconino Plateau (fig. 1), a subregion of the Colorado Plateau south of Grand Canyon, has heightened the awareness of environmental groups, commercial developers, and resource managers to the importance of spring resources. Native Americans in the Grand Canyon region, such as the Havasupai Tribe, are concerned that ground-water pumpage may affect the spring resources. For Native Americans, springs are not only economically important but also culturally significant. The U.S. Geological Survey (USGS) and GCNP began a cooperative program in 1999 under the auspices of the WaterQuality Monitoring and Assessment Partnership, a Clean Water Action Plan program (2002), shared between the USGS and the National Park Service (NPS). Nineteen springs have been sampled to date that issue from the Redwall and Muav Limestones along the south rim of Grand Canyon.
