Connecticut Water Trails Program Water Trails & Water Pollution The Water Cycle and Pollution
The
Water Cycle is, simply put, is the circulation of water in earth. In
fact, the water in the earth's biosphere is used and reused again and
again. This is called water cycle or continuous movement of water
between the earth and the atmosphere. It involves the following
mechanisms:
What's the relation of water cycle and pollution?
According to the water cycle, naturally, water around us will be
absorbed to the land (soil) and rivers will stream from the upstream to
the downstream and released to the sea. In normal situation
organic pollutants are biodegraded by microbes and converted to a form
that brings benefits to the aquatic life. And for the inorganic
pollutants, in the same situation, don't bring to much hazards because
they are widely dispersed and have almost no effect to the environment
which they are released to. In a small scale, both inorganic and organic pollutants safely decompose throughout the stream, their concentration decrease in the sea, and they don't harm the sea ecosystem and its distribution. But in an excessive scale, communities in beach and estuary will be affected by the pollutants, and can heavily harm them.
