Ariz. Admin. Code § R18-4-213 - Standards for Additives, Materials, and Equipment

A. Each product added directly to water during production or treatment shall conform to ANSI/NSF Standard 60. Products covered by this subsection include but are not limited to:

1. Coagulation and flocculation chemicals;

2. Chemicals for corrosion and scale control;

3. Chemicals for softening, precipitation, sequestering, and pH adjustment;

4. Disinfection and oxidation chemicals;

5. Chemicals for fluoridation, defluoridation, algae control, and dechlorination;

6. Dyes and tracers;

7. Antifreezes, antifoamers, regenerants, and separation process scale inhibitors and cleaners; and

8. Water well drilling and rehabilitation aids.

B. Except as identified in subsections (D) and (E), a material or product installed after January 1, 1993, that comes into contact with water or a water treatment chemical shall conform to ANSI/NSF Standard 61. Products and materials covered by this subsection include but are not limited to:

1. Process media, such as carbon and sand;

2. Joining and sealing materials, such as solvents, cements, welding materials, and gaskets;

3. Lubricants;

4. Pipes and related products, such as tanks and fittings;

5. Mechanical devices used in treatment, transmission, or distribution systems such as valves, chlorinators, and separation membranes; and

6. Surface coatings and paints.

C. Evidence that a product conforms to the requirements of this Section shall be the appearance on the product or product package of a seal of a certifying entity that is accredited by the American National Standards Institute to provide the certification.

D. Chemicals and additives certified as conforming to the national sanitation foundation standards comply with the standards required by this section. ... In those instances where chemicals, additives and drinking water system components that come into contact with drinking water are essential to the design, construction or operation of the drinking water system and have not been certified by the national sanitation foundation or have national sanitation foundation certification but are not available from more than one source, the standards shall provide for the use of alternatives which include:

1. Chemicals and additives composed entirely of ingredients determined by the environmental protection agency, the food and drug administration or other federal agencies as appropriate for addition to potable water or aqueous food.

2. Chemicals and additives composed entirely of ingredients listed in the national academy of sciences water chemicals codex.

3. Chemicals, additives and drinking water system components consistent with the specifications of the American water works association.

4. Chemicals, additives and drinking water system components that are designed for use in drinking water systems and that are consistent with the specifications of the American society for testing and materials.

5. Drinking water system components that are historically used or in use in drinking water systems consistent with standard practice and that have not been demonstrated during past applications in the United States to contribute to water contamination. A.R.S. §§ 49-353.01(B) and (C) (2006).

E. The Department exempts the following materials and products from the requirement to conform to ANSI/NSF Standard 61:

1. A concrete structure, tank, or treatment tank basin that is constructed onsite if the structure, tank, or basin is not normally coated or sealed and the construction materials used in the concrete are consistent with subsection (D). If a coating or sealant is specified by the design engineer, the coating or sealant shall comply with ANSI/NSF Standard 61;

2. An earthen reservoir or canal located upstream of water treatment;

3. A water treatment plant that is comprised of components that comply with subsections (B), (C), and (D);

4. A synthetic tank constructed of material that meets Food and Drug Administration standards for a material that comes into contact with drinking water or aqueous food, or a galvanized steel tank, either of which is:

a. Less than 15,000 gallons in capacity, and

b. Used in a public water system with 500 or fewer service connections; or

5. A pipe, treatment plant component, or water distribution system component made of lead-free stainless steel.
