Background & Objectives: Groundwater is exposed to environmental pollution. The leachate produced by wastes in transfer station or municipal solid waste landfill is one of the sources of pollution. In this view, present study was carried out to evaluate the groundwater quality around of municipal solid waste transfer station in Ardabil at 2017. Materials and methods: In this cross sectional study, 6 wells (one control well in the upstream and 5 wells in the downstream) around the ardabil municipal solid waste transfer station were selected according to the existing criteria, and the quality parameters of the samples (Turbidity, pH, EC, TDS, BOD5, COD, Nitrate, Heavy Metals, Coliform and Fecal Coliform and ...) were analyzed according to the standard methods. Also, particle-size analysis of soil was carried out in sampling area and data analysis was performed using Excel software and compared with existing standards, guidelines and standards. Results: In all samples, except for lead (0.07-1 mg/l), Coliform (0-28 MPN/100ml) and Fecal Coliform(0-4 MPN/100ml), other parameters were lower than recommended limit by the criteria and available standards. Also, the amount of sulfate (593.6 mg/l) in well 4 and total Hardness (530 mg/l) in well 3 were higher than the standards recommended for drinking and agricultural purposes. Conclusion: The results of the study showed that the Municipal Solid Waste Transfer Station in Ardabil had no significant effect on the groundwater quality in the surrounding area.
