【Abstract】 The Irrigated areas by Wastewater of Xiaohe River and Fuhe River in Hebei province were chosen to assess both the quality of wastewater and the soil environment. The results indicated that heavy metals in both Xiaohe River and Fuhe River were not higher than that in Water Quality Standard for Farmland Irrigation. After about 20 years of irrigation, the accumulated Cd in the soil was found to be slightly higher than the second grade of National Soil Environmental Quality Standard. In addition, however, using Xiaohe and Fuhe river water for irrigation on land may lead accumulation of As in the studied soil.
