Part 2: Isoconcentration Maps (Isopleth). Using TCE concentrations for various time periods, draw TCE Isoconcentrations (AKA, Isopleths) contour maps. Use your knowledge from Part 1 with regard to the flow of groundwater and interpolation to assist in drawing your isoconcentration contours. Where appropriate, draw contours of 10, 100, 500, and 1000 ppb TCE. It is best to start drawing contours where concentrations are highest and work down. Note that some wells were not installed at the earlier time intervals are labeled as NA. Answer the questions below.

Print from the 1979, 1985, and 1990 tce maps (pdf) Questions: 1) For each time period, describe the location of the highest concentration of TCE? 2) Is there any correlation between groundwater flow and TCE concentration over time? Describe. 3) Do you think that there might be any other sources of TCE contamination besides points [A], , and [C]? Explain
