Industrial solvents, which can damage the liver, kidneys, and nervous

Industrial solvents, which can damage the liver, kidneys, and nervous system, often drain into public water supplies. Currently, tested water is considered pure if the amount of solvent an individual is exposed to through drinking one-half gallon of water per day - roughly what a typical adult drinks per day - does not pose a significant threat to human health. But many toxicologists claim that the standards set by this method does not adequately protect the public.

Which of the following, if true, would best support the claim of the toxicologists mentioned above?


(A) The figure of one-half gallon a day includes water contained in beverages such as soft drinks, which are often bottled at locations distant from where they are consumed.

(B) Some industrial solvents have less toxic but more expensive analogues that industry has not adopted for use.

(C) Water treatment centers usually filter our bacteria and others organisms before the water is pumped into public supply systems.

(D) Industrial polluters are rarely fined or punished, even when they knowingly allow toxic chemicals to enter water supplies

(E) More solvent enters the body through skin absorption, during washing and bathing, than through drinking.
