Abstract: 

• To study and analyse the ground water data in Jaffna Peninsula
• To find the patterns of water quality during various seasons
• To find the patterns of groundwater quality and verify that the quality of groundwater impacts on human health.

• First step data was converted to word file to excel file.
• To  preprocess the data  there exists some ambitiousness about the data such as
• Missing values
• Outliers
•  Measurement scale of the attributes
• Other information of the data set
• Therefore we met Dr.(Mrs).T. Mihunthan, Senior Lecturer, Dept. of Agriculture, University of Jaffna to discuss about it.
• From that discussion we got some information

       About the first data set:

• The data collected duration :- March 2007 to February 2008
• Regions - Thirunelvely and Kondavil
• Amount - 20 wells per region
• Types of well:
• Public
• Domestic
• Domestic and Home Gardening
• Agriculture
• The data was collected monthly wise and the well were chosen randomly.
• In Every type of well 4 samples were collected.
• The purpose for collecting the samples is to identify the quality of the ground water in different land use in different seasons.
• The following contents were measured
• Nitrate-N
• Hardness
• Chloride
• Alkalinity
• EC
• In this data set there is no missing values
• There exists an outlier in the Nitrate-N content at Thirunelvely region.

     From the second data set

• The data was collected from 3 regions in Jaffna peninsula- Varamaradchi, Thenmaradchi and Jaffna
• In every region 20 samples were collected
• In these wells 10 samples were collected from cancer patients home's as well as the other remaining 10 were collected from non-cancer patients home's well.
• From these samples there was an outlier in Sulphate measurement- In correct measurement
