“…Stable isotopes (d 18 O and dD) have been used extensively throughout the world to evaluate hydrometerological processes (Grobe et al, 2000;Yoshimura et al, 2001;Mikalsen and Sejrup, 2000;Noon et al, 2003;Harvey et al, 2002) and sources of water to various water bodies including aquifers (Gosselin et al, 2001;Alyamani, 2001;Criss and Davisson, 1996;Harvey and Sibray, 2001), rivers (Winston and Criss, 2003;Frederickson and Criss, 1999), lakes (Ojiambo et al, 2001;Knöller and Strauch, 2002), springs (Criss et al, 2001;Rose et al, 1996;Cartwright et al, 2000), and mines (Hazen et al, 2002). Specifically in Florida, stable isotopes have been used to evaluate the source of salinity to groundwater aquifer systems (Meyers et al, 1993;Schmerge, 2001), to evaluate seepage rates from lakes (Katz et al, 1995), sources of groundwater recharge (Price, 2001), recharge rates to aquifers (Swancar and Hutchinson, 1995;Krukikas and Giese, 1995) and the degree of evaporation experienced by surface waters (Swart et al, 1989).…”
