Follow directions on the bottle and from online, write on bottle(s) with a sharpie: the name of sample, and your name and address
pack in box and take to the post office.
Results can be shown online if requested, but snail mail gave me results within a week. >Options for results are at the Fifth heading in 'General Information',
"We have several options for receiving your results. All reports will be mailed by 1st class mail, unless instructed otherwise. Other options include:
Mail and FAX
I got two Complete tests one for 'filtered cold', and the other was 'hot softened', just to know what I actually have for water at my house.
I got the iron levels too, for the extra 10 bucks....$53 bucks total, no charge for postage or supplies, and I called after I received the results and invoice, and paid via CC.
It need only cost you $16.50 for a test of your brewing water.
Hope this helps you in making the plunge.
