Introduction

And so it begins...

We are given several years of water sensor readings from rivers and streams in the Boonsong Lekagul Wildlife Reserve from Professors of the Mistford College Hydrology Department. These samples were taken from different locations throughout the reserve, which is not necessary near any of the factories from Kasios. I am now given the task of looking at this data and see if I can find any evidence that can replace or supplement the soil evidence that was destroyed. Let’s go!

History

In 2017, the Kasios Furniture Company was implicated in environmental damage to the Boonsong Lekagul Wildlife Preserve for both dumping toxic waste and polluting the air with chemicals from its manufacturing process. Kasios denied any accusation of industrial waste dumping and stated that there isn’t any ground contamination.

With the assistance from angry ornithology Mistford College Professors, it was reported that there was a new range station being built at the site. However, soil samples taken from the site were inconclusive in detecting Methylosmolene, the major toxic culprit of the suspected dumping.

Since soil samples are not reliable sources anymore, it is time to look at the hydrology data from the reserve. I am given a map of the Preserve, with named sampling sites indicated on the map. I am also provided with readings from each sampling station over time for several different chemicals and water properties.

Some Information to Start With

Methylosmolene is the worst volatile organic compound (VOC) being monitored. It makes sense to focus on its readings.

The Questions

Question 1: 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?

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?

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?
