 The article describes an algorithm for CFS (Calculation of Fluid Systems) computer program designed to calculate levels, state, distribution of content and volume of water and liquid light petroleum products in a lens formed on a water table during its fluctuations. The program consists of the blocks: data input, parameter transformation, value calculation and formation of input variable arrays on dates, identification and calculation of fluid system, analysis and correction of calculations, selection of zones with different states of liquid light petroleum products, formation of the array of water content and light petroleum products values, treatment of output data and calculation of changes in water and light petroleum products volumes vertically in a water table fluctuation zone, output of tables and results for chosen dates in a file.
