The occurrence and migration of TCs were investigated at the catchment scale. TCs decayed exponentially in paddy soil, while linearly in mixed canal and sewer. The attenuation of the TCs in the sewer was relatively faster than in the paddy soil. TCs were easily deposited in water-sediment systems and sewage ponds. Multi-ponds provide a natural and efficient way to mitigate TC pollution risk to rivers.
