In summarizing more than a decade of environmental monitoring data from the Hanford Site, we noted that grouping data by analysis, rather than by medium, enhanced visual as well as statistical interpretations. By plotting running-averages of individual radionuclides on the same graph, for different media, we evaluated environmental trends to determine whether or not a local impact had been observed. This approach may enhance ones ability to interpret environmental monitoring data collected following an unplanned release of radionuclides. This technique provides a more holistic approach to the evaluation of environmental monitoring data than has traditionally been practiced.
