Pooling Data

SADA provides a way for the user to apply modeling and summarization applications to all contaminants within a particular media at once. This capability is available by selecting Pooled Data from the Contaminant Selection box on the secondary toolbar. Selecting this item produces a data plot that shows every sample location for every contaminant included in the analysis for the current media type. See Contaminant Manager for information about including/excluding contaminants. Notice that there is no legend associated with this plot. These data plots essentially demonstrate the distribution of information locations across space.

Information Retrieval, Statistical Analysis, and Human Health Risk toolbar buttons are available and will produce tabular results for all contaminants; however, the user may not exclude any type of contaminant (rad, nonrad, unregistered) here without explicitly removing it from the list of included contaminants in Contaminant Manager.

Pooled data sources may extend over both radionuclides and nonradionuclides and may be modeled with varying interpolation schemes. As a result, the only common ground for describing or characterizing the information in a single map is through the human health risk models. For this reason, all other mapping options are disabled except for point risk mapping and risk contour mapping. See Risk Maps.
