This article was partucularly interesting! After hurricane Sandy, much of the northeastern coast is flooded. Floodwater is known to contain harmful bacteria and disease. Because floodwater mixes with both sewage, river, and rain water it is reasonable to assume that it is full of harmful materials. Citizens of the area have been instructed to stay clear of the stagnant water; as well as, boil all tap water before consuming to rid it of harmful bacteria. If i was in their situation i would do as they say, and avoid standing water until it is all pumped out or evaporated.
