this could potentially be read in two ways, both of which are incorrect:
(INCORRECT READING 1)
"that" is a pronoun (in the same way you'd point at a menu and say "i want that
to use that
in this way - by itself
as a pronoun, as a "pointing word" - is always incorrect in formal written english.
"that" CAN be used as a pronoun, but only if it's in a parallel construction (such as the capacity of tank A
vs. that of tank B
(INCORRECT READING 2)
it's a relative pronoun (in the same way you'd write "here's the book that
two things wrong here.
one, you don't put a comma before this kind of "that".
two, even if this were written correctly (i.e., without the comma), which it isn't, you'd still be saying 20% of the water that is more than the great lakes
. i.e., there is SOME SPECIFIC water that is "more than the great lakes", and we're talking about 20% of that water. that doesn't make sense.
so, wrong either way.
