Dear Evans,
The cheapest option is by blending but this relies on an alternative source of low nitrate water and a vessel where blending can occur. Dependent on the nitrate levels, the amount of low nitrate source may be minimal. Targeting the water for consumption against any used for washing may also reduce the volume of quantity of water you need to treat.
Good Luck with finding your solution
