Results The results indicated that pH value and chemical oxygen demand of the water at urban river surge and a certain section were eligible,but amino-nitrogen,dissolved oxygen and heat-resistant coliform were not eligible,the turbidity was high,the water quality did not meet the Hygienic Standard for Swimming Place (GB 9667-1996).
