Abstract: The objective of the investigation was to establish the main variable factors (index parameters) determining the methane production level, using for this propose static modelling with the application of Pearson's correlation coefficient (r) and multiple regression. The waste disposal site in Janik, the municipality of Kunów, was monitored in the years 2008-2011. 16 series of markings were obtained, which were analysed and the findings provided the basis for the investigation. The above mentioned investigation and field observations permitted the creation of database, which was analysed statistically using STATISTICA 10 package.
