| Description |
Water samples from four springs and five wells in basalt aquifers near Spring Creek National Fish Hatchery in Skamania County, Washington, were collected and analyzed for selected inorganic ions and stable isotopes. Eight samples were analyzed for carbon-14 (14C), carbon-13 (13C), and either chlorofluorocarbons (CFCs) or tritium. This work was done to estimate the age (residence time, or time elapsed since recharge) of water issuing from springs at the hatchery. If CFCs are present in ground water, the presence of at least a component of modern (post-1944) water is indicated. CFC-dating suggests that ground water several hundred feet below land surface in the Underwood Heights area north of the hatchery, including ground water discharging from the hatchery springs, contains modern water. In contrast, CFC-dating suggests that deeper ground water such as that withdrawn from the Hatchery Well may contain little or no modern water. Concentrations of 14C in water can yield 14C-based grou |
