M: Well, no one could survive without water, but you see pollution has been making more and more water unable for drinking.

它们通常可以分成两类：直接污染源和间接污染源。

M: Well, direct ones are the pollution directly from factories, refineries waste treatment plants etc., aren’t they?
额，直接污染源是那些从工厂、精炼厂、污水处理厂排放出来的污染，是吗？

W: Yeah. They are emitted directly into urban water supplies.
是的。它们直接排放到城市供水系统中。

M: But what about the indirect ones?
但是间接污染源是什么呢？

W: Indirect sources include contaminants that enter the water supply from soils or groundwater systems and from the atmosphere via rainwater.
