This paper aims to examine Dickens`s later novels from the perspective of ecocriticism. Especially it delves into the ways Dickens treats water and other environmental elements related to water, such as river, mud, fog, and so on. Victorian England experiences unprecedented environmental problems as well as brilliant success in industrialism. Because of the water pollution, the Parliament had to close up, and people could not drink the tap water at all. The water pollution eventually led to epidemics. As is well known, Dickens`s later novels critically deal with a lot of social issues. It is noteworthy that in doing so Dickens uses polluted rivers, stinky fog and filthy mud, which are all related to water, to effectively develop the themes. In a sense, environment acts as a character rather than a background. That there is always clean water, or the sense of its being there, in ideal places in his novels testifies how seriously Dickens takes the problems of water. (Chungnam National University)
