The confusion is related to the many different ways in which the concentrations of the nitrate and nitrite ions in forages and water are reported after chemical analysis.
The toxic dose of nitrate or nitrite is more a function of the amount a given animal receives in relation to his body weight and the time over which it was received than it is to a specific concentration in feed and water.
Safe limits for feeding are given in percent NO of the sample or in amount of nitrate (in grams) consumed per 100 pounds of body weight of the animal per day.

 Nitrate Filter - nitrate, nitrite, whole house water filter, water softener, nitrate removal
Nitrates can be found in water supplies that are in areas where there are heavy use of fertilizers.
Rather than waste either the sodium or the potassium we place the special nitrate resin on top of regular softening resin and along with removing the nitrates and sulfates we also soften the water with the same amount of salt being used.
A laboratory may also choose to express nitrate as nitrate (NO3 as NO3) in the water analysis, and in this case, the EPA MCL is 44.2 ppm (10 ppm as N is equivalent to 44.2 ppm as NO3).
