TThe Kasios furniture company has been implicated in environmental damage to the Boonsong Lekagul Wildlife Preserve. Kasios deny all accusations of industrial waste dumpling. Last year, Kasios spokesperson reassured that there isn’t any ground contamination near the remote ranger station suggested by the analysis. Professors from Mistford College went to the site themselves to take samples. However, soil samples were inconclusive and investigators have taken a different approach. The task of this project is to investigate the hydrology data from across the preserve. The Mistford College of Hydrology have come forwad with several years of water sensor readings from rivers in the preserve. My task has been to investigate such samples. The given dataset looks like this:

id	value	sample date	measure
2221	2	Boonsri	11-Jan-98v	Water temperature
2223	9.1	Boonsri	11-Jan-98	Dissolved oxygen } Figure1: sample of the dataset given measure unit 1,2,3-Trichlorobenzene µg/l 1,2,4-Trichlorobenzene µg/l Acenaphthene µg/l Acenaphthylene µg/l AGOC-3A µg/l Alachlor µg/l Aldrin µg/l alpha-Hexachlorocyclohexane µg/l Aluminium µg/l Ammonium mg/l Anionic active surfactants mg/l Anthracene µg/l AOX µg/l Figure2: Sample of the second dataset given Figure3: Snapshot of the map given. Questions: 1. Trends: 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? Your submission for this questions should contain no more than 10 images and 1000 words. 2. Anomalies: 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? Your submission for this question should contain no more than 6 images and 500 words. 3. Conclusions: 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? Your submission for this question should contain no more than 6 images and 500 words.

The Gates Based on the data description and reserve map, the restricted gates are highlighted in red. 600px 2. The time 250px 3. The Cars 200px 4. The Visitors The visitors were segmented as follows based on the nature of their movements in the reserve. 400px The graph below shows the composition of each cluster by car types. 400px 5. The Data Timestamp: the date and time the sensor reading was taken Car-id: the assigned car ID from the entry gate Car-type: Vehicle type as enumerated above. “P” is appended when it is a park vehicle Gate-name: name of the sensors taking the reading.
