Subject: Nestle Purelife Water - hardness?
 

Hi all, I plan on using bottled water for my new Rocket Giotto machine.  I have Nestle Pure Life bottled water which is very cheap at Costco.
I have no idea how to read a water mineral/hardness report.
Can anyone in the know, look at this report, and tell me if this is a good, soft water to use?? :

Thanks!!!

Water hardness is determined by measuring the total concentrations of Calcium (Ca) and Magnesium (Mg) ions in the water.
The US Geological Survey uses the following ranges to determine a general classification:
  • Soft < 60 ppm.
  • Moderately hard - 60 - 120 ppm.
  • Hard - 121 to 180 ppm.
  • Very hard > 180 ppm

where ppm = parts per million.

Looking at the analysis for Pure Life, the Ca varies from 20 - 100 ppm, and the Mg from 4.2 - 33 ppm, so the hardness could vary from soft to hard, and taking an average would come out as moderately hard.

For very minimal cost, you can get water hardness test kits from pet stores that deal in aquariums, or your water authority can supply an analysis free of charge for your tap water (assuming you are on a municipal water supply).

Hope this helps,

Alan

Thanks!
I'll try to get some test strips locally to check the water.

Cheers
