Background. e purpose of ANSI/AWWA D130 is to provide direction and guidance for selecting and purchasing geomembrane materials used to line or cover potable water reservoirs. e st

24、andard is based on the accumulated knowledge and experience of owners, consulting engineers, manufacturers, fabricators, and installers of geomembrane liners and oating covers. e standard should be used in conjunction with AWWA Manual M25, Flexible-Membrane Covers and Linings for Potable-Water Reser

25、voirs, to dene suitable application for use of these materials. I.B. History. In 1975, AWWA appointed a committee to study and report on the adaptability of geomembrane liners (so called exible membranes) and oating covers for use within the water industry. e committee presented its report at the 19

26、75 AWWA Annual Conference. is report included a recommendation to appoint a task group to prepare a standard to describe the use of geomembrane linings and oating covers. Subsequently, the AWWA Standards Committee on Flexible Reservoir Covers and Linings for Potable Water Storage was established in

27、June 1976. e initial goal of the committee was to prepare a manual with guidelines for design, installation, and maintenance of a geomembrane oating cover or lining, or both. e committee completed a rst draft of the manual in February 1 983 and submitted it for consideration by the AWWA Standards Co

28、uncil later that same year. e rst edition of the standard, designated ANSI/AWWA D130-87, was approved by the AWWA Board of Directors on Jan. 26, 1987, and by ANSI on May 28, 1987. e second edition contained minor technical revisions and was approved on Feb. 4, 1996. e third edition was approved on J

29、une 16, 2002. is edition was approved on June 12, 2011. I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certication program fo

30、r direct and indirect drinking water additives. Other members of the original consortium included the American Water Works Association Research Foundation (AwwaRF, now Water Research Foundation) and the Conference of * American National Standards Institute, 25 West 43rd Street, Fourth Floor, New Yor

Copyright2011AmericanWaterWorksAssociation.AllRightsReserved. viii State Health and Environmental Managers (COSHEM). e American Water Works Association (AWWA) and the Association of State Drinking Water Administrators (

32、ASDWA) joined later. In the United States, authority to regulate products for use in, or in contact with, drinking water rests with individual states.* Local agencies may choose to impose requirements more stringent than those required by the state. To evaluate the health eects of products and drink

33、ing water additives from such products, state and local agencies may use various references, including 1. An advisory program formerly administered by USEPA, Oce of Drinking Water, discontinued on Apr. 7, 1990. 2. Specic policies of the state or local agency. 3. Two standards developed under the dir

34、ection of NSF, NSF /ANSI 60, Drinking Water Treatment ChemicalsHealth Eects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Eects. 4. Other references, including AWWA standards, Food Chemicals Codex, Water Chemicals Codex, and other standards considered appropriate by the state or local age

35、ncy. Various certication organizations may be involved in certifying products in accor- dance with NSF/ANSI 61. Individual states or local agencies have authority to accept or accredit certication organizations within their jurisdiction. Accreditation of certi- cation organizations may vary from jur

36、isdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 61 does not stipulate a maximum allowable level (MAL) of a contaminant for substances not regulated by a USEPA nal maximum contaminant level (MCL). e MALs of an unspecied list of “unregulated contaminants”

37、 are based on toxicity testing guidelines (noncarcinogens) and risk characterization methodology (carcinogens). Use of Annex A procedures may not always be identical, depending on the certier. ANSI/AWWA D130 does not address additives requirements. us, users of this standard should consult the appro

38、priate state or local agency having jurisdiction in order to 1. Determine additives requirements, including applicable standards. 2. Determine the status of certications by all parties oering to certify prod- ucts for contact with, or treatment of, drinking water. 3. Determine current information on

39、 product certication. * Persons outside the United States should contact the appropriate authority having jurisdiction. NSF International, 789 N. Dixboro Road, Ann Arbor, MI 48105.

Water industry experience has established the critical need for a well-dened, regularly executed, site-specic inspection and maintenance program with

41、written documentation of procedures. See chapter 3 of AWWA Manual M25. III. Use of is Standard. It is the responsibility of the user of an A WWA standard to determine that the products described in that standard are suitable for use in the particular application under consideration. III.A.
