Scope:

The water treatment systems covered in this standard shall be self-regeneration anion exchange systems designed to reduce nitrate from drinking water. The systems shall use anion exchange media that prevents nitrate dumping. Point of Entry (POE) anion exchange water treatment products covered in this Listing Evaluation Criteria (LEC) are intended to be used in residential and commercial applications to reduce nitrate from drinking water. The water treatment systems covered in this LEC shall be self-regeneration anion exchange systems designed to reduce nitrate from drinking water. The systems shall use anion exchange media that prevents nitrate dumping.Depending on the influent water quality, anion exchange systems, if not regenerated correctly, can dump or increase the amount of nitrate in the drinking water if other anions such as sulfates are exchanged by the resin.Non-regenerating residential water treatment systems designed to reduce nitrates shall be tested to NSF/ANSI 53.

Project need:

The main source of nitrate contamination found in drinking water comes from inorganic fertilizers and animal and septic tank waste. Water supplies that are most vulnerable to the nitrate contamination are typically found in agricultural areas in private and public wells. The need to develop a new Joint Canada-U.S. National Standard for Point of Entry Anion Exchange–Nitrate Reduction Devices to verify the ability of an automatic Regenerable Anion Exchange System to reduce Nitrate, and there are no current Canadian Standard that covers this type of products.
