22、er sulfate is used primarily as an algicide in potable water. It is available 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 sa

23、lts. Copper sulfate crystals form in the concentrated solution and grow 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

24、copper sulfate is generally produced in printed-circuit-board shops, where proprietary etchant solutions are used to dissolve copper from printed circuit boards. If a sulfuric-acid-based etchant solution is used, it becomes saturated with cop- per ions and sulfate ions. Small crystals of copper sulf

25、ate form and are mechanically removed. The presence of various impurities and 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 facto

26、rs, including algae type and growth habits as well as application method and equipment to be used. The application rate will depend on algae type and species as well as water characteristics, including pH, alkalinity and hardness, presence of suspended solids, density of algae growth, and water temp

27、erature. For potable water, the US Environ- mental Protection Agency (USEPA) 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 Water R

28、egulations. USEPA, Office of Drinking Water, has set the action level at 1.3 mg/L copper (Cu) as the National Primary Drinking Water Standard. Under most use conditions, the effective dose is considerably less than the established residue tolerance. * American National Standards Institute, 25 West 4

30、 15, 1957. It was developed by the AWWA Water Purification Division and also was submitted for review to producers and consumers whose comments were then considered by a referee. It was approved as a standard without revision on Jan. 26, 1959, and published as AWWA B602-59. This standard was revised

31、 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 as follows: Designation Date of Approval B602-57T Sept. 15, 1957 B602-59 Jan. 26, 1959 B602-80 Jan. 28, 1980 B602-86 Jan. 27, 1986 B602-91 Jan.

In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF Interna

33、tional (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) and the Conference of State Health and Environmental Manag

34、ers (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 rests with individual states.* Local agencies may choose to i

35、mpose 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 developed under the direction of NSF : NSF/ANSI 60, Drinking Wa

36、ter Treatment ChemicalsHealth Effects, and NSF/ANSI 61, Drinking Water System ComponentsHealth Effects. * Persons outside the United States should contact the appropriate authority having jurisdiction.

37、s Association. All Rights Reserved. ix Various certification organizations may be involved in certifying products in accor- dance with NSF/ANSI 60. Individual states or local agencies have authority to accept or accredit certification organizations within their jurisdictions. Accreditation of certi-

38、 fication 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 not regulated by a USEPA final maximum contaminant level (MCL). The MALs of an

39、 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, depending on the certifier. ANSI/AWWA B602 addresses additives requirements in Sec. 4.

40、3.3 of the standard. The transfer of contaminants from chemicals to processed water or to residual solids is becoming a problem of great concern. The language in Sec. 4.3.3 is a recommenda - tion only for direct additives used in the treatment of potable water to be certified by an accredited certif

41、ication 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 should also consult the appropriate state or local agency having jurisdiction

42、 in order to 1. Determine additives requirements, including applicable standards. 2. Determine the status of certifications by parties offering to certify products for contact with, or treatment of, drinking water. 3. Determine current information on product certification. II. Special Issues. II.A.

43、Storage and Handling Precautions. 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 this product separately to prevent cross-contamination with other chemicals

44、. Proper attention to safety requirements should be followed. Protective clothing should be worn while handling copper sulfate pentahydrate, especially goggles to pro- tect against dust or splashes into the eyes. II.B. Disposal. As an algicide, copper sulfate pentahydrate is covered under the Federa

45、l 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 regulations. Any spilled solid material or waste liquid material must be dis

46、posed of in compliance with FIFRA and Copyright 2017 American Water Works Association. All Rights Reserved. x local regulations. Questions on proper disposal can be answered by the state pesticide control office or regional USEPA hazardous waste representative. II.C. NPDES Permitting. Point source d

47、ischarges of biological pesticides and chemical pesticides that leave a residue in waters of the United States are required to comply with National Pollutant Discharge Elimination System (NPDES) requirements. Operators wanting to apply copper sulfate to waters of the United States impaired for coppe

48、r or sulfate must obtain coverage under an NPDES individual permit rather than the USEPAs Pesticide General Permit. Information about the requirements for these permits can be found at https:/www. epa.gov/npdes/pesticide-applications-1. III. Use of This Standard. It is the responsibility of the user

49、 of an AWWA standard to determine that the products described in that standard are suitable for use in the particular application being considered. III.A. Purchaser Options and Alternatives.
