research puzzles we are having. If anyone disagrees with this idea please say so -- we are building a community culture here. So here's a question a student and I are encountering. I'd like any ideas from colleagues on this list on QGIS-related analysis:</span><o:p></o:p></p>

contaminants. I have a student trying to use QGIS to analyze these data. We want to understand the spatial-temporal patterns in this data (where/when there are particularly dangerous levels, and where/when there are not). </span><o:p></o:p></p>
