Introduction. I. Background. I.A. Copper sulfate primarily is used as an algicide in potable water. It is avai

21、lable both as a commercial product and as a by-product of the printed- circuit-board industry. The commercial product is produced by reacting a solution of sulfuric acid with copper metal, cupric oxide, or basic cupric copper salts. Copper sulfate crystals form in the concentrated solution and grow

22、in size in a characteristic crystalline shape. A broad range of crystal sizes is produced by controlling the length of crystallization time or by fracturing the larger crystals and screening to the desired sizes. The by-product copper sulfate is generally produced in printed-circuit-board shops, whe

23、re proprietary etchant solutions are used to dissolve copper from printed-circuit boards. If a sulfuric acidbased etchant solution is used, it becomes saturated with copper ions and sulfate ions. Small crystals of copper sulfate form and are mechanically removed. The presence of various impurities a

24、nd their amounts in the copper sulfate depend on the impurities present in the starting materials or the solution in which the crystals grow. The selection of crystal size for use in algae control depends on a number of factors, including algae type and growth habits as well as application method an

25、d equipment to be used. The application rate will depend on algae type and species as well as water char- acteristics, including pH, alkalinity and hardness, presence of suspended solids, den- sity of algae growth, and water temperature. For potable water, the US Environmental Protection Agency (USE

26、PA) has set a tolerance for the maximum residue of copper at 1 ppm, or equal to 4 ppm as copper sulfate pentahydrate (CuSO 4 5H 2 O) (40 CFR* 185.1200), which also is the secondary standard under the US National Drinking Wa- ter Regulations. USEPA, Office of Drinking Water, has set the Action Level

27、at 1.3 mg/L copper (Cu) as the Primary Drinking Water Standard. Under most use conditions, the effective dose is considerably less than the established residue tolerance. History. I.B. This standard was first approved as tentative on Sept. 15, 1957. It was developed by the AWWA Water Purification Di

28、vision and also was submitted * Code of Federal Regulations, US Government Printing Office, Superintendent of Documents, Washington, DC 20402. Forewordviii for review to producers and consumers whose comments were then considered by a referee. It was approved as a standard without revision on Jan. 2

29、6, 1959, and published as AWWA B602-59. This standard was revised by the AWWA Standards Committee on Taste and Odor Control Chemicals. The dates of approval and numerical designation of past editions of ANSI/AWWA B602 are listed below. Designation Date of Approval B602-57T Sept. 15, 1957 B602-59 Jan

Acceptance. I.C. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative a

31、greement 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 American Water Works Association Research Foundation (Aww

32、aRF) 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 wate

33、r rests 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

34、developed 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 accordance with NSF/ANSI 60. Individual states or local

35、 agencies have authority to * Persons outside the United States should contact the appropriate authority having jurisdiction. NSF International, 789 N. Dixboro Road, Ann Arbor, MI 48113.

36、t certification organizations within their jurisdiction. Accreditation of certification organizations may vary from jurisdiction to jurisdiction. Annex A, “Toxicology Review and Evaluation Procedures,” to NSF/ANSI 60 does not stipulate a maximum allowable level (MAL) of a contaminant for substances

37、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 (carcinogens). Use of Annex A procedures may not always be identical, dependin

38、g on the certifier. ANSI/AWWA B602 addresses additives requirements in Sec. 4.4 of the standard. The transfer of contaminants from chemicals to processed water or the residual solids is becoming a problem of great concern. The language in Sec. 4.4.3 is a recommendation only for direct additives used

39、 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 make this certification a requirement for the product. Users of this standard sho

40、uld also consult the appropriate state or local agency having jurisdiction in order to Determine additives requirements, including applicable standards. 1. Determine the status of certifications by parties offering to certify products 2. for contact with, or treatment of, drinking water. Determine c

41、urrent information on product certification. 3. Special Issues. II. Storage and Handling Precautions. II.A. Copper sulfate pentahydrate crystals are highly soluble in water but do not react with water. Store this pesticide product in a dry place in its original container until ready for use. Store t

42、his product separately to prevent cross-contamination with other chemicals. Proper attention to safety requirements should be followed. Protective clothing should be worn while handling copper sulfate pentahydrate, especially goggles to protect against dust or splashes into the eyes. Disposal. II.B.

43、 As an algicide, copper sulfate pentahydrate is covered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as a pesticide. It must be packaged and labeled as a pesticide for algae control. Packaging material that is empty must be disposed of in compliance with FIFRA and local regu

44、lations. Any spilled solid material or waste liquid material must be disposed of in compliance with FIFRA and local regulations. Questions on proper disposal can be answered by your state pesticide control office or your regional USEPA hazardous waste representative.x Use of This Standard. III. It i

45、s the responsibility of the user of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered. Purchaser Options and Alternatives. III.A. The following items should be covered by the purchaser: Standard usedthat is,

46、 ANSI/AWWA B602, Copper Sulfate, of latest 1. revision. Crystal size designation. 2. Whether compliance with NSF/ANSI 60, Drinking Water Treatment 3. ChemicalsHealth Effects, is required.
