 　　5.2 Pollution 环境污染
M: Well, no one could survive without water, but you see pollution has been making more and more water unable for drinking.
W: Yeah. Water pollution has for a long time been a major concern among the environmental issues.
M: But what are the sources of water pollution?
W: They could generally be divided into two categories: direct and indirect contaminant sources.
M: Well, direct ones are the pollution directly from factories, refineries¹ waste treatment plants etc., aren’t they?
W: Yeah. They are emitted directly into urban water supplies.
M: But what about the indirect ones?
W: Indirect sources include contaminants that enter the water supply from soils or groundwater systems and from the atmosphere via rainwater.
M: I see. For the sake of us all, we should be an active participator in the prevention of it.
W: Sure. It's an issue asking for everyone's participation².

W：是啊，长期以来水污染一直都是环境问题中备受关注的。
M：但是都有哪些污染源呢？
W：可以分为两大类，即直接污染和间接污染。
M：嗯，直接污染是指工厂、冶炼厂、废水处理厂等地方直接排出来的废物，是吧？

M：那间接污染是什么呢？
W：间接污染是从泥土、地下水系统以及通过雨水从大气中进入水源的有害物。
