CASE STUDY 2 (Fig. 27) The study site is in the area where the hydrocarbon products were transferred to tank wagons about 10 yea<strong>rs</strong> ago. The task was to survey the site for possible residual contamination. An old and almost biodegraded contamination is indicated between 25 and 35 mete<strong>rs</strong> (distance) at the profiles 5 and 10. Some hydrocarbon pollution remains as the PID channel indicates the presence of organic compounds at the given part of the surveyed site. IR methane channel indicates presence of methane. IR TP channel measures methane plus hydrocarbon compounds. The TP value perfectly correspond with methane channel, which indicates old contamination, showing up as methane, with much bacterial activity resulting in methane production. IR CO2 channel indicates increasing concentration of CO2 , which is connected to bacterial activity (bacteria produce CO2 and consume O2). The graph shows a decrease in oxygen, which corresponds well with the increase of CO2 . . Conclusion: Methane, CO2 and O2 values indicate old contamination with a high bacteria activity Some residual contamination is still present. .

DATA INTERPRETATION Railway Station 14. 6. 2000 Fig. 28 74 CASE STUDY 3 (Fig. 28) PID measurements made at the railway station shows the largest hydrocarbon contamination from 40 to 95 m along all profiles. Several small contaminated domains in the surveyed area, are confirmed by the IR TP analyzer (see the third graph) Methane channel shows relatively high concentrations of methane, which is characteristic of old contamination where bacterial activity has already started. At the position of the main contamination, the TP channel shows higher values than the methane channel. This indicates the presence of hydrocarbon contamination. There is also an indication on the TP channel at 100 –110 m on the profiles 95 and 100, of fresh hydrocarbon contamination. No methane is present. Bacterial activity is expressed by high concentrations of CO2 at the position of the main contaminated area (compare also with the PID channel).
