Ammonia nitrogen pollution in the groundwater of a chemical fertilizer contaminated site in North China was investigated. The results show that ammonia nitrogen was detected in all groundwater samples,and 100%of the samples exceeded standard for groundwater quality of China( 0. 2 mg/L),the maximum detection concentration of ammonia nitrogen was 578 mg/L,which is 2890 times beyond the standard value of groundwater quality standard of China( 0. 2 mg/L). The heavy pollution areas of ammonia nitrogen were mainly located in the carbonization workshop,the urea synthesis workshop and its downstream,sewage treatment area and sewage pipeline. The cyanide pollution hotspot was located in the sewage treatment area. The leakage and spill of ammonium and wastewater from storage tanks and pipelines were the main sources of cyanide and ammonia. Factors affecting the ammonia nitrogen and cyanide concentration of groundwater in study area included the chemical and physicochemical properties of ammonia nitrogen and cyanide and high vulnerability of groundwater in this site.
