Environmental monitoring continued at the Weldon Spring Site in 1989. Numerous exposure pathways were monitored in 1989, including groundwater, surface water, and air. Analytical parameters included radionuclides, nitroaromatic compounds, inorganic anions, and direct gamma exposure. The results are being used to calculate exposure doses (where applicable) so the impact of the site on potentially exposed populations can be assessed. Off-site exposures did not dramatically increase in 1989 over exposures calculated in previous years. Contaminated groundwater did not affect private water supplies or the St. Charles County Well Field. Surface water containing elevated uranium activity continued to impact the Femme Osage Slough and several lakes in the August A. Busch Memorial Wildlife Area. Elevated radon exposures at the Weldon Spring Quarry continued in 1989 due to the unusually dry conditions. Off-site gamma, radon and air particulate exposures remained indistinguishable from background. Off-site monitoring demonstrated that exposure at the Francis Howell High School, the Busch Wildlife Area Headquarters, and the Weldon Spring Training Area is indistinguishable from background levels. No spills occurred at the Weldon Spring Site in 1989. 39 refs., 39 figs., 23 tabs.
