Got it, thank you very much for taking the time to check it out and get back to me.Don't bother looking at TDS to gauge anything about the usability of tap water. It is totally useless for that purpose. If they sent 0 ppm TDS RO/DI water to you, it would definitely be not OK to use by the time it got to you, dissolving copper pipes along the way.
I just looked up woonsocket in the other thread (page 4 of the link you show) and posted that 10% of homes have copper over 72 ppb. Not usable.
