When it rains, the water flows over these surfaces, picking up animal feces and other pollutants and washing them into drainage ditches or storm drains, many of which lead directly to urban lakes, coastal creeks or beach areas.

• 一旦下雨，流经这些地面的水流，就会连带将动物粪便及其他污染物冲刷到排水沟或雨水沟，而这些沟渠大部份又直通到都市内的湖泊、海岸溪流或海滩地区。
