Isotope Studies on the Middle San
Led by: Chris Eastoe, hydrologist with the University of Arizona
Where: Cascabel Community Center, Cascabel Arizona
Chris told a group of about 30 mostly Cascabel residents about studies that he has been doing on isotopes in groundwater of the Middle San Pedro River. He explained how isotopes are used to determine age and sources of groundwater, and referenced specific
subareas of the Cascabel community and what isotopes are telling us about the origins of groundwater in these local areas. He also explained the effects of groundwater chemistry on water quality. The presentation was preceded by breakfast.
Co-sponsored by the Cascabel Working Group.
