Will an RO system remove Nitrates?

Whelp got the first of my test results back today from the water testing company. The good news is there is no E. coli. That would have required treating the well as it can not be filtered. The bad news is that my suspicions are correct and the nitrites are at 23.2 mg/l. The safe level is considered under 10 mg/l. So I have to filter the water. Other minerals and contaminants we tested for I won't get the results for another 2 weeks or so but I guess it doesn't much matter since I have to filter the water for the Nitrate anyway.
Were the units nitrate or nitrate-nitrogen?


I wouldn't worry about nitrate in drinking water:

But being well water there's the potential for much more toxic substances to be present. I would use RO for those...
