Report:
For accurate analysis of the water sample water should have been collected from different points of the pond. But we collected water from only one point. So it might not be a representative one.
Water sample is collected from a pond, which is approximately a rectangular in shape and its length is about 200 m, and width is approximately 100 m. There is surrounded a road. The sample was collected about 30m apart from the east bank and about 50m from the north bank. The color of water in the pond is greenish. Trees surround the sides of the pond. Leaves falling from the trees become rotten and pollute the water. There are many fishes in the pond. There are some water plants surrounding the pond. The pond is paved at one side of the bank. There are buildings at all sides. People through garbage into the pond, such as (plastic bag, bottle, paper etc). There is a paved floor beside the pond to wash clothes and utensils. This water gets mixed with pond water and makes it dirty.
