Natural Wetlands and Waste management in Rural area

Hi everyone.

I want to assess the links between wetland and sanitation issues in rural area and find out where the solid and liquid waste produced in a village end up.

I used Google earth to make a map of land usage in the village (Landscape),  then Recorded the GPS position of boreholes, toilets, waste dump places in villages, then outline channels that collect rainwater into wetland.

The point is I am not that good in statistics, and am not sure how to analyse the data I collected to assess role played by Natural Wetlands in waste management. 

Your idea and comments are most welcome.
