2、07) ii AWWA Standard This document is an American Water Works Association (AWWA) standard. It is not a specification. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifications. The AWWA standards usually
3、 contain options that must be evaluated by the user of the standard. Until each optional feature is specified by the user, the product or service is not fully defined. AWWA pub- lication of a standard does not constitute endorsement of any product or product type, nor does AWWA test, certify, or app
4、rove any product. The use of AWWA standards is entirely voluntary. This standard does not supersede or take precedence over or displace any applicable law, regulation, or code of any governmental authority. AWWA standards are intended to represent a consensus of the water supply industry that the pr
5、oduct described will provide satisfactory service. When AWWA revises or withdraws this standard, an official notice of action will be placed in the Official Notice section of Journal - American Water Works Association. The action becomes effective on the first day of the month fol- lowing the month
6、of Journal - American Water Works Association publication of the official notice. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer,
7、 the consumer, and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether that person has ap - proved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standar
8、d. American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions. Producers of goods made in conformity with an American National Standard are encour - aged to state on their own responsibility in advertising and promotional materials or on tags or
9、 labels that the goods are produced in conformity with particular American National Standards. Caution n oti Ce : The American National Standards Institute (ANSI) approval date on the front cover of this standard indicates completion of the ANSI approval process. This American National Standard may
10、be revised or withdrawn at any time. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of ANSI approval.

This edition was approved on Jan. 24, 2015. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a
19、cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct and indirect drinking water additives. Other members of the original consortium included the Water Research Foundation (formerly AwwaRF)
20、and the Conference of State Health and Environmental Managers (COSHEM). The American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (ASDWA) joined later. In the United States, authority to regulate products for use in, or in contact with, drinking water res
21、ts with individual states. Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health effects of products and drinking water additives from such products, state and local agencies may use various references, including two standards develo
22、ped under the direction of NSF : NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 60. Individual states or local age
23、ncies have authority to accept * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New York, NY 10036. Water Research Foundation, 6666 West Quincy Avenue, Denver, CO 80235.

Accreditation of certi- fication organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 60 does not
25、 stipulate a maximum allowable level (MAL) of a contaminant for substances not regulated by a USEPA final maximum contaminant level (MCL). The MALs of an unspecified list of “unregulated contaminants” are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (ca
26、rcinogens). Use of Annex A procedures may not always be identical, depending on the certifier. ANSI/AWWA B306 addresses additives requirements in Sec. 4.3.4 of the standard. The transfer of contaminants from chemicals to processed water or to residual solids is becoming a problem of great concern. T
27、he language in Sec. 4.3.4 is a recommenda- tion only for direct additives used in the treatment of potable water to be certified by an accredited certification organization in accordance with NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects. However, users of the standard may opt to mak
28、e this certification a requirement for the product. Users of this standard should also consult the appropriate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable standards. 2. Determine the status of certifications by parties offering to c
29、ertify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. This standard has no applicable information for this section. III. Use of This Standard. It is the responsibility of the user of an AWWA standard to deter
30、mine that the products described in that standard are suitable for use in the particular application being considered. III.A. Purchaser Options and Alternatives. The following information should be provided by the purchaser: 1. Standard usedthat is, ANSI/AWWA B306, Aqua Ammonia, of latest revision.
31、2. Whether compliance with NSF/ANSI 60, Drinking Water Treatment ChemicalsHealth Effects, is required. 3. Size and type of bulk storage container to be used and details on transfer equipment available for receiving bulk shipments. If bulk storage is not used, state required container sizes. 4. Detai
32、ls of other federal, state or provincial, and local requirements (Section 4). 5. Physical form(s) and quantity (Sec. 4.1). ix 6. Tolerances allowed for concentrations (Sec. 4.2). 7. Specific maximum impurity content limits, if required (Sec. 4.3). 8. Whether the purchaser will reject product from co
33、ntainers or packaging with missing or damaged seals. The purchaser may reject product from bulk containers or packages with missing or damaged seals unless the purchasers tests of representa- tive samples, conducted in accordance with Sec. 5.1 and Sec. 5.2, demonstrate that the product meets the sta
34、ndard. Failure to meet the standard or absence of, or irregularities in, seals may be sufficient cause to reject a shipment. 9. Whether alternative security measures have been adopted to replace or aug- ment the security measures set out in Sec. 6.2.4 and 6.2.5. 10. An affidavit of compliance or cer
35、tified analysis or both, if required (Sec. 6.3). III.B. Modification to Standard. Any modification to the provisions, definitions, or terminology in this standard must be provided by the purchaser. I V. Major Revisions. Major changes made to the standard in this revision include the following: 1. In
36、clusion of the use of this material for wastewater and reclaimed water as well as definitions of these terms (Sections 1 and 3). 2. Inclusion of a requirement for compliance with the Safe Drinking Water Act and other federal regulations (Section 4). 3. Inclusion of guidance for rejection of the mate
37、rial and concentration varia- tion (Sec. 5.3 and 5.4). 4. Inclusion of a requirement for tamper-evident packaging (Sec. 6.2.4 and 6.2.5). V. Comments.
