Amendments to Minnesota Rules, Chapter 4725, effective August 4, 2008, require that chlorine materials used for well disinfection
must meet the requirements of American National Standards Institute (ANSI)/NSF International (NSF) Standard 60-2003e as
determined by a person accredited by the ANSI under ANSI Standard Z34.1-1993 or be registered by the United States Environmental
Protection Agency (U.S. EPA) in accordance with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) sec. 3(c)(7)(A) as an
antimicrobial pesticide for use in potable water. Chlorine compounds with additives such as perfumes or algaecides must not be used
for disinfection. The amended rule also allows the use of an alternate disinfection material if the material is a biocide meeting the
material and use standards of this part, and provides biocidal activity equivalent to the chlorine concentrations and contact times
required in this part.
Annual renewal of product registrations at the Minnesota Department of Agriculture begins in January. Many products listed here were
registered in 2008 and are currently in the renewal process for 2009. End users may continue to use previously registered products
they have on hand. A manufacturer may not sell new product unless the registration is current.
This list is generated from listings found on http://state.ceris.purdue.edu/doc/mn/statemn.html. Listings are found by clicking on "Search
Minnesota Pesticide Data," selecting "Site of Application," entering keyword "potable," and selecting "Human Drinking Water Systems
(Potable)."
Only those products labeled specifically for well disinfection are included in this list of Minnesota Department of Health Well
Management Section approved products (177 of 550 total products listed on website for “Human Drinking Water Systems [Potable]).
Many sodium chlorite, sodium chlorate, chlorine dioxide, and chlorine gas products are listed for use in disinfection of water supplies
and/or water storage systems, but are not labeled for use in well disinfection, and should not be used for well disinfection. (Sodium
chlorite [NaClO2] and sodium chlorate [NaClO3] are used to generate chlorine dioxide.)
Some calcium hypochlorite and sodium hypochlorite products are on U.S. EPA's list, but are not labeled for well disinfection, so do not
appear on this list, and should not be used for well disinfection.
