This report presents summaries and interpretations of the environmental monitoring data collected during 1993 at Pantex Plant. Additionally, it outlines site environmental management performance, summarizes compliance with applicable environmental regulations, and describes significant programs and achievements. Environmental monitoring is composed of two principal collection and analysis activities for radiological and nonradiological constituents: (1) effluent monitoring involving liquid and airborne effluents to characterize and quantify releases and (2) environmental surveillance involving water, soil, vegetation, and biota and measurement of external radiation to characterize environmental impacts of Pantex Plant. Data are used to assess impacts of operations to the public and the environment and to demonstrate compliance with applicable standards for both radiological and nonradiological contaminants. In 1993 more than 270 onsite and offsite locations were monitored regularly with 4000 samples collected and analyzed. Data from a location at the US Department of Agriculture Bushland Agricultural Research Service and historical data are also presented for reference.
