Transfer station (TS) is an integral part of present-day municipal solid waste (MSW) management systems. To provide information for the incorporation of waste facilities within the current integrated waste management system, the authors measured the existing environmental quality at five MSW TSs. Discharged wastewater, air, and noise were monitored and assayed at the five TSs in Beijing in 2001–2006 during rainy seasons (RSs) and dry seasons (DSs). Except Ammonia (NH3) and hydrogen sulfide (H2S), the analytical results of total suspended particles (TSPs), odor, noise, ammonium nitrogen (NH4 +-N), chemical oxygen demand (CODCr), biochemical oxygen demand (BOD5), suspended solid (SS), and fecal coliform concentrations were all degree-varied higher than the criteria limit in China. Using fuzzy mathematics, the environmental quality of MSW TSs in Beijing was classified into five categories, with levels of certainty of belonging to di erent categories and evaluations. The result indicated that the whole environmental quality of Datun TS, Majialou TS, and Xiaowuji TS, in Beijing, were bad during 2001–2006 in RSs and DSs. Except in 2002, the entire environmental quality of the Wuluju TS during 2001–2006 in RSs was poor. Only in the DSs of 2002 and 2003 was the whole environmental quality of the Wuluju TS good. The whole environmental quality of the Yamenkou TS during 2001–2006 in DSs was bad, which was lower than that of 2001–2006 DSs.
