How polluted is the water in west lake in the area of Tay Ho?

Anna collected data for the Simpson's Diversity test, and did a similar experimant as the one at V-Resort. Collecting samples from 8 different areas around West Lake in the Tay Ho area, then looked at the diversity of species in each of the areas and later added them together to see the overall average diversity in the lake. Charlie measured the pH of West Lake in eight different areas using a pH pen. Ayaka measured the level of phosphate in the lake water, using phosphate test kit. The data shows different levels of phosphates in 8 different areas around the lake. Three trials were carried out and found the average level of phosphate in each area. What Andrew did was to use the 8 water samples from chemistry lab to measure the refractive index of each samples of water to see if the refractive index depend on the phosphate level. Abdullah was managed to interview about 10 different people about the topic of west lake pollution. The people had very similar answers and some were very interesting.

As hypothesis, this group assumed that the West Lake would be very polluted from its appearance. However, from the data collected at the West Lake, the group found out that West Lake is not as polluted as it appears to be. The group concluded that the lake is polluted; however not as much as it was hypothesized, and the pollution differs depending on the place. The area near the stairs was more polluted than the other areas. Locals feel that it has been become more polluted, yet they still swim in it. Therefore, the group concluded that the west lake is not as polluted as people think and in fact the locals are not greatly affected by the pollution of lake water.
