Notes:
a
This list was compiled using listings found on the NSF internet site, www.nsf.org. Other organizations accredited by ANSI
to perform testing and certification to the NSF/ANSI standards for drinking water treatment additives did not have any
listings for drilling aids or sealants at the time this list was compiled. Products that are crossed out (strikeout) have been
listed previously, but are not on the current list. These products should not be considered approved for use unless the
product package is marked with the NSF certification. Products that are highlighted are listings that have been added since
the January 12, 2009, update of this Minnesota Department of Health (MDH) list. Periodic updates to this list will be made
available on the MDH Well Management Section Web site at:
www.health.state.mn.us/divs/eh/wells/lwcinfo/drillaids.html.
b
A cementitious well sealant and a few graphite-based well sealants that are listed by NSF do not appear on this list and
have not yet been approved by MDH for use as well sealants in regulated wells and borings in Minnesota.
1
Products listed as well drilling aids, drilling fluids, and foaming agents are designed to be flushed out prior to using the
system for drinking water. The well is to be properly flushed and drained before being placed in service.
2
For products listed as well sealants, the well is to be properly flushed and drained before being placed in service.
3
a. These products should not be used in constructing wells in highly porous formations such as cavernous limestone.
b. Certification of these products is based on a well drilling model with the following assumptions:
1. The amount of well drilling fluid used is 3780 liters (1,000 gallons), to which the drilling fluid has been added at the
level specified in ANSI/NSF Standard 60, or at the manufacturer’s recommended level.
2. The aquifer contains 3.1 million liters of water (815,000 gallons), based on a 0.5 acre aquifer of 6.1 meters depth (20
feet) and 25 percent porosity.
3. The bore hole is 61 meters in total depth (200 feet), the screen is 6.1 meters in length (20 feet), and the bore hole
diameter is 25.4 cm. (10 inches).
4. The amount of well drilling fluid removed from the well during construction is equal to the combined volumes of
the casing, the screen and bore hole annulus around the casing and the screen, plus an additional amount removed
through well disinfection and development (90 percent of that initially applied is removed).
4
These products contain polyacrylamides. Because questions remain regarding potential health risks from exposure to these
products, the MDH recommends that they not be used in potable water applications.
5
Certification of this product is based on a well drilling model using assumptions stated in ANSI/NSF Standard 60, Section
8 for well drilling foamers. These products are designed to be flushed out prior to using the system for drinking water.
Before being placed in service, the well is to be properly flushed according to the manufacturer’s use instructions.
6
These products are intended to be mixed with sand at ratios specified by the manufacturer. Some bentonite and sand
mixtures do not meet the grouting materials specifications found in Minnesota Rules, part 4725.0100, subpart 21d or part
4725.7050, subpart 1, item D. These mixtures may not be used unless a variance is obtained from the MDH. The MDH has
granted variances to allow use of these products.
The August 4, 2008, amendments to Minnesota Rules, Chapter 4725 allow the use of thermally enhanced bentonite grout
for grouting the bore hole of a vertical heat exchanger, provided that the thermally enhanced bentonite grout consists of a
fluid mixture of not more than 17.5 gallons of water, not more than 200 pounds of sand with 80 percent or more of the sand
smaller than 0.0117 inch (passing U.S. Sieve No. 50), and a minimum of 50 pounds of bentonite.
Following is a partial list of requirements for drilling fluids and grouts used in wells and borings in Minnesota (complete
requirements can be found in Minnesota Rules, Chapter 4725, Wells and Borings):
• Drilling fluid additives, including bentonite, must meet the requirements of ANSI/NSF Standard 60-2003e.
• Bentonite used for grout must meet ANSI/NSF Standard 60, or be a natural bentonite without additives.
• Grout must be mixed into a water slurry and pumped through a tremie pipe or the casing.
• Bentonite pellets, chips, and dry granular bentonite may be used only as an intermediate seal between a gravel pack and
grout in any regulated well or boring. The layer of bentonite pellets, bentonite chips, or granular bentonite must not exceed
5 feet in thickness, must not extend into a confining layer, and must not extend more than 10 feet above the static water
level.

Following is a partial list of requirements for drilling fluids and grouts used in wells and borings in Minnesota
(complete requirements can be found in Minnesota Rules, Chapter 4725, Wells and Borings):
●
Drilling fluid additives, including bentonite, must meet the requirements of American National Standards
Institute (ANSI)/ NSF International (NSF) Standard 60-2003e. The MDH has developed a supplementary list
(above) of foams and lost-circulation materials.
●
Bentonite used for grout must meet ANSI/NSF Standard 60, or be a natural bentonite without additives.
●
Grout must be mixed into a water slurry and pumped through a tremie pipe or the casing.
●
Bentonite pellets, chips, and dry granular bentonite may be used only as an intermediate seal between a gravel
pack and grout in any regulated well or boring. The layer of bentonite pellets, bentonite chips, or granular
bentonite must not exceed 5 feet in thickness, must not extend into a confining layer, and must not extend
more than 10 feet above the static water level.

Amendments to Minnesota Rules, Chapter 4725, effective August 4, 2008, require that chlorine materials used for well disinfection must meet the
requirements of ANSI/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 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.
420
Annual renewal of product registrations at the MDA 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 MDH 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.

Well Cap Note – All regulated wells and borings must have a permanent watertight and vermin-proof cap
installed on the casing (the innermost casing, if the well or boring has multiple casings). The cap must be
an overlapping well cap with compression gasket, a threaded or welded well cap, a sanitary well seal, or
the extension of the casing at least 1 inch into the base of a pump. The screened vent required for a watersupply well may be incorporated into the underside of the well cap.
Casing Connection Note – A pitless unit that connects to the well casing with a compression seal must
provide for the well casing to extend at least 2.5 inches into the throat of the pitless unit.
