Water balanceWith the test results and meteorological data, the water balance the Lubna landfill has beenevaluated. The full water balance for the landfill was as follows (Fig. 11 ):P+W+H 1 +D p +K g =E t +E w + ∆R+Sp+H 2 +H 3where:P = precipitation,W = water form moisture of disposed wastes,H 1 = groundwater inflow,K g = capillary ascent,D p = surface water inflow,E t = evaporation from the vicinity,E w = evaporation from the open reservoirs,∆R = retention of the landfill body,S p = surface water outflow,H 2 = groundwater outflow,H 3 = excess leachate from drainage system (for utilisation in treatment plant).The small water volume becoming from biodegradation processes was lost in the equation.10

The water from the wastes (W) consists approximately 25% of thetotal wastes volume. The retention capacity (∆R) was determined at the level of 50% of the watercontent of wastes (from tests on the Lubna and Radiowo landfills).It was assumed that the landfill surface obtained 21.64 ha, while the surface of open waterreservoirs was 0.28 ha. The components of the average annual water balance for the Lubnawaste body are presented in Table 3.11
