In home canning or in cooking, boiling the water will not remove nitrate or nitrite. In fact, heat will concentrate and increase the content. The Environmental Protection Agency states the maximum total nitrate and nitrite level is 10 parts per million.
Treat well water with anion exchange, distillation, electrodialysis or reverse osmosis processes. Contact a water treatment professional to select the right treatment for your well water.
