Generally, the sources of the liquid waste generated by the
MSWP have the following contributions: 1% for the SU, 12% for
the CU, 31% for the PP, and 56% for the MP. However, these ratios
may vary because the amount of leachates generated by landfill
prisms is strongly influenced by rainfall; in the studied area, the
average annual rainfall is 600 mm/year (Lorenc, 2005).
