Figure.1.6 Age of Tube wells Vs. Arsenic Contents
Lead Contents were compared with the age of tube wells. It was found that lead contents
were in equal proportion regardless of tube well age. The graph shows that tube wells of long
and short age have lead contents in mix proportion. Some tube wells of short age have higher
lead contents while some tube wells of long age have higher lead contents vice versa.
Literally it depicts true picture that age has no impact on proportion of lead contents
