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:

The Public Laboratory for Open Technology and Science (Public Lab) is a community, supported by a 501(c)3 non-profit, that develops and applies open-source tools to environmental exploration and investigation. By democratizing inexpensive and accessible do-it-yourself techniques, Public Lab creates a collaborative network of practitioners who actively re-imagine the human relationship with the environment.

The core Public Lab program is focused on community science, in which we research open-source hardware and software tools and methods to generate knowledge and share data about community environmental health. Our goal is to increase the ability of underserved communities to identify, redress, remediate, and create awareness and accountability around environmental concerns. Public Lab achieves this by providing online and offline training, education and support, and by focusing on locally-relevant outcomes that emphasize human capacity and understanding.
