by warren |

Parts & Crafts campers worked with me to produce this guide to sample preparation of oil or tar contaminated soil. This covers just the sample prep and how to see fluorescence in samples with a green laser. You'll need to construct a spectrometer to measure the samples' colors and try to identify the contaminant:

You can find the sample jars we used here:
