Nitrates

harif87 · 01-13-2007, 04:38 PM

I was just wondering, how high of a reading of nitrates would be considered dangerous to humans? I ask this because all of the bottled water here in Israel has nitrates in excess of 15 ppm. Some brands have nitrate levels at 33 ppm, as claimed on the bottle by the manufacturer. Could this probably make a person slightly ill? In any case im staying away from the water because it has other stuff i would rather not drink.

..huh, I've never heard of that

45mg/l is the U.S. Federal standard of acceptable levels of NO3 in drinking water.

what is that in ppm?

parts per million

no...I wasnt asking what ppm is I was asking what 45mg/l translates to in ppm

hmm 45 x 10E-3 g/1000g in a liter of water * 1E6 = 45 ppm

The tap water where we are is less than optimal.

Nitrate: 40ppm
pH: 8.5 - 9.0 (sometimes off the scale)
kH: 40

Not to mention the overwhelming aroma of chlorine when you run it.

Needless to say, we have an RO unit for our tank water.

Sure, safe for us to drink, but it will kill a fish!

Wow you'd need a heavily planted tanginikan cichlid tank for that water.
