I had a walk thru home inspection on my new place today and the home inspecter guy pulled one of these things out and tested my well water..... it read 169ppm .... I am like "oh that sounds bad.....".. then he said WOW this is the purest water Ive ever tested!!! Poland Spring bottled water is 180ppm!!

My tap water is better than poland spring!!

How amazing is that tester...

 

[ok awesome]

poland spring isn't very good. every time i go to the northeast they have it everywhere. it tastes like puddle water compared to kentwood/abita.

I have one, Metairie TDS is 235 which is pretty good

My Sparta aquifer water currently measures 222 out the tap and 179 from the refrigerator filter.

I have a filter that takes it down to zero for my aquarium, it runs through 3 different prefilters, then a reverse osmosis membrane, then a canister of nuclear grade de-ionization resin

TDS is not a good indicator of how "clean " the water is. TDS is total dissoved solids, if those solids are sodium, chloride and other mineral thats OK but if those solids are mercury and lead...not so good. In addition it wont measure any bacterial contamination. Some of the water in the "steams" in the Florida parishes measure 250 TDS, but I wouldnt drink it.

TDS is good for telling you if its hard water or soft and thats it. Of course 0 TDS is deionized or distilled water which could still have bacteria. Bottom line....dont use this to go test pond water for drinking..

I was told by this clown that this was the measure of potalability....

in the Army he had huge RO trailers that would filter water out of the Tigris river, I think they must have put bleach in it too for the remaining bacteria

RO is perfectly fine to get out bacteria...to a certain extent. IF the RO filters get colonized on the "down hill side" your screwed. With RO, as long as there isnt a hole in the filter membrane only water passes. Bleach(chlorine) may have been used to help with storage time and any bacteria that got past the RO membrane.

hammer...potablity as far as solids( too hard is not really drinkable) yes but not microbiological. TDS is minerals and ions, not critters. They arent dissolved.
