Discriminate between the immediate and chronic effects of water pollution and explain why chronic pollution is a more serious long term threat.

Answer:

The immediate effects of water pollution such as fish kills and official advisories and restrictions on water use and consumption are visible and immediately noticed by a community. Chronic pollution occurs over long periods of time, giving communities and individuals time to become accustomed to it. There is less of a sense of urgency to the problem which actually allows it to grow and persist more readily.
