Dear Evans,
If no low nitrate well water sources would be available to replace or blend the nitrate rich well water, then nitrate shall best be reduced to inert nitrogen gas as applied at full scale over at least 30 years. This nitrate reduction can be achieved in various ways but - as always - the most sustainable and cost-effective solution for a specific case depends on the design flow rate (m³/h) and on the nitrate concentration (mg/l). Also the raw well water composition, pH and temperature would be important. Please specify as to advise more specifically for your case.

flow rate of 20 litres/minute borehore and 70 mg-N/l, temperature 25 oC, pH = 6.5,,, pls may you forward me more detailes via envaros@yahoo.com..
