Nothern of Viet Nam is the location where thousands of households are using the drilled well’s water located near ten thousands of graves, yet also affected by dozens of big factories nearby and crematoriums.

     -------------------------------------------

     A resident complained in behalf of many others: "This is frustrated, over ten years since the drilled well’s water of the factory is broken due to broken cylinder, mud has covered and blocked, it is impossible to use the water, so the people have to drill the wells themselves for water. But the drilled well water source here is really not safe!."
     The water resided in his house is muddy yellow along with foamy creamed and dead fish/stinky smell. Therefore, you could imagine what other host's water condition is like.
