Characterize the past and most recent situation with respect to chemical contamination in the Boonsong Lekagul waterways. Do you see any trends of possible interest in this investigation?

Statement	Graph
1.Year 1998---2007 There are some measures having value of 0, I can’t decide whether the measurement is 0 or didn’t have measure. So, I regard it as missing value and delete. There are some strange values in this dataset. For same location, same time and same measure, but there are different values. I think it’s repetitive value. So, I get average of them.
1.Year 2008---2016 There are some measures having value of 0, I can’t decide whether the measurement is 0 or didn’t have measure. So, I regard it as missing value and delete.

Question 2

What anomalies do you find in the waterway samples dataset? How do these affect your analysis of potential problems to the environment? Is the Hydrology Department collecting sufficient data to understand the comprehensive situation across the Preserve? What changes would you propose to make in the sampling approach to best understand the situation?

Anomalies	Graph
1.Water temperature Water temperature went high trend from 2009. And from graph we can see temperature have seasonal patterns, it lead to dissolved oxygen have seasonal patterns. When temperature goes higher, dissolved oxygen goes down. They two have negative relationships
2.Iron Quantity of Iron had an extremely increase in 2003 Q3. And it much more higher than every other years and quarters. There must be some uncommon events in that quarter or its sample datas have something wrong

Question 3

After reviewing the data, do any of your findings cause particular concern for the Pipit or other wildlife? Would you suggest any changes in the sampling strategy to better understand the waterways situation in the Preserve?
