==Effects of contamination== 

 This section was misnamed and poorly written. If I were an English teacher, I would give the student an F. 

 *The story of the arsenic contamination of the groundwater in Bangladesh is a tragic one. Diarrheal diseases have long plagued the developing world as a major cause of death, especially in children. Prior to the 1970s, Bangladesh had one of the highest infant mortality rates in the world. 

 This section begins by saying there was a lot of suffering. Then it will go on to say that they dug wells, which was good (!) but then arsenic was found in the water. 

 It does not say how many people died or got sick as a result of the arsenic contamination. It only says that one mortality rate went down. Does this mean arsenic is good? I don't think that was the point.
