This investigation and visual guide seeks to provide a range of UV color outputs based on oil type. After sampling 10 different kinds of oil - 5 household oils and 5 light crude oils including gasoline - we created a spectrum of color based on light output produced under UV. We developed a system of taking each oil type, diluting it in 1.5 oz of mineral oil and lighting each sample under UV to produce the color range. What may appear as any kind of oil with little color differentiation or visibility in normal lighting, becomes much more prevalent under UV. When placed in ROYGBV color order one notices that the more toxic and volatile the oil sample, the closer to the green/blue/violet end of the spectrum. This will hopefully provide a guide for those that may test samples in future to understand what type of oils they may be dealing with.




























Initial Interest After sifting through ECHO data to analyze an industrial park in Lakewood, New Jersey. The database showed that most facilities were within regulation while some were significant non-compliers. This led to an investigation of the difficulty in understanding and tracing non-point source pollution of water contamination. The watershed that all these facilities flow into is severely polluted with the Bay suffering from major pollution and environmental issues, but the facilities themselves seem to have a small environmental impact when investigated individually.



This shows how a UV Flourescent Spectrometer could determine sources of non-point source contamination in Lakewood Township.
