>>Introduction

There is a river passing through our community. The elderly people say that the Plum Tree Creek supplied water to the resident for the use of agriculture and drinking in the past when it was riches in fishes, shrimps and crabs. However, its beauty remains no more. Causes floods when typhoon occurs, dirty and smelly became the impression of Plum Tree Creek. We want to find out the reason of the transformation, deal with the pollution, bring the clear stream back and giving fish and shrimp a chance of survival. We believe people will get close to the stream once again and our community will become better and better. Plum Tree Creek has a strong relationship with our community. However, she is sick now. Why? Can we find out the reason and propose the solution for school and people in our community? By the aid of chemical reagents, instruments and benthos research we found out that there are different problems in different river basins. Water plunder from the origin, agriculture and husbandry pollution from the headstream; pigsty of the midstream; domestic sewage of the downstream. To solve the problem, we need to combine environmental education, community cooperation and policy of the government to bring back the vitality of Plum Tree Creek.
