It appears that you know more about chemistry than some of us. Please explain why the "chemical" water I drink when in Philadelphia is different than the distilled water I buy at the grocery store.

Water has the chemical formula H2O. What comes out of the tap has a variety of other molecules in it. Most common will be elements such a calcium and magnesium which stain your bathtub and sink fixtures. There are also a number of other chemicals that haven't been completely filtered out at the water plant. When water is distilled it is evaporated and condensed to remove other products which don't have the same boiling point. The distillation process and the number of distillations will determine how pure the water is.
Water is a chemical and a solvent like other solvents. They all behave differently. Water can be extremely dangerous and reactive in certain situations.
As I mentioned before, the process of soaking in water or soaking in Towle solution is detectable. It might be cost prohibitive for the grading companies to detect it, but it is detectable.
