Abstract :

Background and Objective: Study of landfill of urban solid wastes is important because of its different kind of pollution. The most important pollutants of landfill, is leachate of the resulting from solid wastes. Solid waste leachate may penetrate into surface and underground water and pollute these resources. This place is located near one of Siahroud River branch. And is named Zarjoub. This river evacuates the pollution resulting from solid waste leachate with other urban, industrial and agricultural pollutants at Anzali wetland. Methods: In this research, the qualification of Rasht landfill and Kacha River were studied for leachate contamination. For purpose BOD, DO, PH, TP and COD parameters were studied in two humid and arid seasons. Findings:  The averages of COD, BOD, Do and TP in river are 3862.5 and 1326.25, 0.3 and 6/5 Mg/L. Also the average of pH is 7.01. Discussion and Counclusion: The results show that observed amounts are higher than the standards of environmental protection organization. Furthermore, the pollution resulting from leachate showed remarkable increase in comparison with the results of experiments of 1997.
