Abstract:

The diagnosis of the leachate has shown a strong no biodegradable (COD/BOD5 varies between 3 and 50) organic pollution. High NTK concentrations vary between 2296 and 490 mg∙L-1 have been observed which can induce a nuisance of surface water near the discharge and receiving of leachate. The analysis of metallic elements of leachate showed a high concentration in chrome 1598 µg∙L-1 as maximum value and 27 µg∙L-1 as minimum and maximum high in As, Cu, Ni, Pb and Zn which testifies to the pollution of leachate from the discharge gross receiving every type of waste (management waste and industrial waste). The results showned that P1, P3, P5, P6, P8, P9, and P10 have high concentrations in NO3- (389 and 111 mg∙L-1) exceeding the standards of potability (50 mg∙L-1). Sinks P1, P5, P7, P8, P9 and P10 are highly mineralized since the conductivity varies between 5990 and 1480 µS∙cm-1, while the organic matter remains higher than the standard of 2 mg∙L-1 The analysis of metallic element in groundwater have shown significant concentrations in Ni (175 and 59 µg∙L-1), Zn (266 and 6 µg∙L-1) and Pb (165 and 30 µg∙L-1) confirming the degradation of groundwater. These results show that the public discharge has a considerable impact on the groundwater near the discharge.
