Question

求高人翻译2（英译中）!!谢谢

urface water can become contaminated in many ways. Surface water can be contaminated when hazardous substances are discharged directly from an outfall pipe or channel or when they receive contaminated storm water runoff. Direct discharges can come from industrial sources or from certain older sewer systems that overflow during wet weather. Storm water runoff becomes contaminated when rain water comes into contact with contaminated soil and either dissolves the contamination or carries contaminated soil particles. Surface water can also be contaminated when contaminated groundwater reaches the surface through a spring, or when contaminants in the air are deposited on the surface waterSurface water can also be contaminated when contaminated groundwater reaches the surface through a spring, or when contaminants in the air are deposited on the surface water. Contaminated soil particles carried by storm water runoff or contaminants from the air can sink to the bottom of a surface water body, mix with the sediment, and remain.
第一个是Surface water，掉了一个S。谢谢！

Answer 1

地表水的污染源来自很多方面。它会被下水管道中排出的含有有害物质的废水污染，或者它接收了被污染的雨水的流入。直接污染排放来自工业排放以及一些老旧的排水系统，这些排水系统一到雨天就会溢出来。当雨水接触到被污染的土地，或是溶入了污染物、携带了被污染的土壤颗粒，就会同样被污染。当地下水以涌泉的方式到达地表，或者空气中的污染物沉积到水中，同样会污染地表水。被污染的土壤颗粒及空气中的污染物会沉降到地表水体底部，与沉积物和残骸混在一起。
