If that's measured with Dist 1 PPM meter, it's OK
It's impure enough to get the reaction started fairly fast and not so impure as to cause contamination problems.
I actually prefer DW that reads 1 PPM over the more pure water.
Extremely pure water does not pull enough current to prevent fluffy deposits from growing [which slow the reaction even further and wastes silver] and can take several hours to draw significant current which will throw any attempts at timing a batch right out the window unless an ammeter is employed to set a base reading.

I use WalMart DW and find that it is about 0.5-0.9 ppm.
That is why I was wondering about the 'steam-distilled' bit.

Hi John, WalMart's DW has been discussed within the last few weeks,
but I'm not sure what was said, but I think the answer is no.

BTW, is WalMart DW steam-distilled?
