Same here, and it's concentrate which means you will add another gallon of distilled water ($2 from Walmart Pharmacy) and you have all the needed coolant for under $25USD and you know it's the right type for your car. While there, I would never use tap water in these engines, not even to 'flush' them with that garden hose. In many areas the tap water has high amounts of calcium carbonate dissolved in it which only waits to deposit inside the engine and block coolant passages - remember that the heater core inner tubes are very thin.
I have checked once a quality of supposed to be distilled water bought from CVS, tester showed 70+ ppm, which is way too much even for single pass distillation. Even good bottled water like Poland Spring is cleaner.

My tap water was 14 ppm (reverse osmosis), I switched to tap water ;)

Its kind of like the bottled water industry - convincing people it is safer to drink bottled water, a completely unregulated industry, over municipal water, with required bi-annual testing and reporting (varies by state/Province, but you get the picture)

Have some 20 ppb Benzene with your Perrier to go, please.

70 ppm as Sodium probably means they just filled the jugs with municipal water, thats way too high for distillled, indeed.
