Recreation, consumption of wild game, risk, and the department of energy sites: Perceptions of people attending the Lewiston, ID, "Roundup"

Several federal agencies are reclaiming land through remediation and restoration, and are considering potential future land uses that are compatible with current land uses and local needs. Understanding potential recreational and wild game consumption patterns and risk perceptions are critical for determining cleanup levels and assessing potential risk associated with certain uses. In this article, recreational rates of people attending the Lewiston "Roundup" rodeo in northwestern Idaho were examined, as well as their perceptions of the safety of consuming fish and game from two Department of Energy (DOE) facilities: the Hanford Site and the Idaho National Engineering and Environmental laboratory (INEEL). These are two of DOE's largest sites. Lewiston is closer to Hanford but is in the same state as INEEL. Men engaged in significantly higher hunting and fishing rates than women, but there were no gender differences in camping and hiking rates. Rates of hunting and camping decreased significantly with age, while rates of hiking were lowest for 31- to 45-yr-olds. Level of education generally was not related to rates of recreation. Over 70% of the subjects are deer, elk, and self-caught fish; 30-50% ate grouse, moose, and waterfowl; and fewer people ate other game species. Overall, subjects were less concerned about earing the fish and game from INEEL than from Hanford and more people thought Hanford should be cleaned up completely compared to INEEL. Mean rates of fishing hiking, and camping all exceeded the DOE's maximum recreational exposure assumption of 14 d/yr used in their future use documents. Although at present people are generally not allowed access to DOE lands for recreation, recreation is one future land use being considered for these federal facilities. Given that some people would engage in multiple activities, the potential exists for people living in the general region of Hanford and INEEL to exceed the 14-d exposure assumption. The relative gender differences in recreational rater mean that men are potentially more at risk, particularly since hunting (on both sites) and fishing (on Hanford) are attractive.
