UGH.......Body in water tank.

I was absolutely horrified to read in the Straits times that a Body was found in the water tank.The thought of drinking that water.Ugh..............It makes me sick. If I was staying there then I cannot imagine what I would have felt.I really cannot understand how this could happen.This is very dangerous as some crazy person can poison the water.I hope that that all the Estates will have tighter security so nothing of this sort happens ever again.
