No.water shall be provided or rendered available for use to the public for drinking or domestic use which is of unsatisfactory;sanitary quality and is not approved by the State Department of.Health. The sanitary quality shall be determined by the bacterio- logical, chemical, and physical standards as published by the U. S. Public Health Service„ and contained in "Public Health Service Drinking Water Standards, 1946." The following are the bacteriological, physical and chemical requirements contained in these standards and are quoted for reference as follows: "3.2 Application - Applications 3.21 and 3.22 given below shall govern when ten milliliter (10 ml.) portions are used and applications 3.23 and 3.24 will govern when one hundred milliliter (100 ml.) portions are used.# "3.21. Of all the standard ten milliliter (10 ml.) portions examined per month in accordance with the speci- fied procedure, not more than ten (10) per cent shall show the presence of organisms of the coliform group. "3.22. Occasionally three (3) or more of the five (5) equal ten milliliter (10 ml.) portions constituting a single standard sample may show the presence of organisms of the coliform group, provided that this shall not be allowable if it occurs in consecutive samples or in more than: (a) Five (5) per cent of the standard samples when twenty (20) or.more samples have been examined per month. (b) One (1) standard sample when less than twenty (20) samples have been examined per month. "Provided further, That when three or more of the five equal ten milliliter (10 ml.) portions constituting a single standard sample show the presence of organisms of the coliform group,'daily samples from the same sampling point shall be collected promptly and examined until the results obtained from at least two consecutive samples show the water to be of satisfactory quality. #It is to be understood that in the examination of any water supply the series of samples for any one month must conform to both of the above requirements, either 3.21 and 3.22 or 3.23 and 3.24. 113.23. Of all the standard one hundred milliliter (100 ml.) portions examined per month in accordance with the specified procedure, not more than sixty (60) per cent shall show the presence of organisms of the coliform group. 113.24. Occasionally all of the five (5) equal one hundred milliliter (100 ml.) portions constituting a single standard sample may show the presence of organisms of the coliform group, provided that this shall not be allowable if it occurs in consecu.tive samples or in -more than: (a) Twenty (20) per cent of the standard samples when five (5) or more samples have been examined per month. (b) One (1) standard sample when less than five (5) samples have been examined per month. "Provided further, That when all five of the standard one hundred milliliter (100 ml.) portions constitut- ing a single standard sample show the presence of organisms of the coliform group, daily samples from the same sampling point shall be collected promptly and examined until the results obtained from at least two consecutive samples show the water to be of satisfactory quality. "4.1. Physical characteristics. The turbidity of the water shall not exceed 10 p. p. m. (silica scale), nor shall the color exceed 20 (platinum cobalt scale). The water shall have no objectionable taste or odor. "4.2. Chemical characteristics. The water shall not contain an excessive amount of soluble mineral substance, nor excessive amounts of any chemicals employed in treatment. Under ordinary circumstances, the analytical evidence that the water satisfies the physical and chemical standards given in sections 4.1 and 4.21 and simple evidence that it is acceptable for taste and odor will be sufficient for certification with respect to physical and chemical characteristics. 114.21. The presence of -lead (Pb) in.excess of 0.1 p. p. m., of fluoride in excess of 1.5 p. p. m., of arsenic in excess of 0.05 p. p. m., of selenium in excess of 0.05 p. p. m., of hexavalent chromium in excess of 0.05 p. p. m., shall constitute grounds for rejection of the supply. "These limits are given in parts per million by weight. Salts of barium hexavalent chromium, heavy metal glucosides, or other substances with deleterious physiological effects shall not be added to the system for water treatment purposes. 0 "Ordinarily analysis for,these:.substances need be made only semiannually. If, however, there is.some presumption of unfitness because of these elements, periodic determina- tion for the element in question should be made more frequently. 114.22. The following chemical substances which may be present in natural or treated waters should preferably not occur in excess of the following concentrations where other more suitable supplies are available in the judgment of the certifying authority. Copper (Cu) should not exceed 3.0 p. p. m. Iron (Fe) and manganese (Mn) together should not exceed 0.3 p. p. m. Magnesium (Nig) should not exceed 125 p. p. m.

(3) -The wallowing of hogs and other animals in and along the streams, and similar abuses, shall not be permitted within five miles of the water supply intake. (4) No dwelling houses, or other place where persons reside, congregate or are employed, shall be built or maintained - on any watershed without being provided with a sanitary privy or system for the disposal of sewage, constructed and maintained in accordance with the rules and regula- tions of the State Board of Health. (5) The State Board of Health shall, when it becomes desir- able because of local conditions', enact special rules and regulations for the protection from contamination of the watershed from which any specific public water supply is derived. These rules and regulations will deal with the methods of sewage and waste disposal and other matters in so far as they may affect the sanitary quality of the water tributary to the, supply. .54.160 Cities to Define Watersheds. Whenever any of the cities or towns of the State of Washington shall seek or take steps to exercise authority or jurisdiction over any watershed, or any property acquired for works, reservoirs, systems, branches or pipes, said municipal corporation shall first by ordinance, define the limits of the territory or property over which it may seek to take steps to exercise such jurisdiction. A copy of said ordinance shall be filed with the State Department of Health. Cross -Connections .54.170 Definitions. (1) "Cross -Connection"- A cross -connection is any physical arrangement whereby a public or semipublic water supply system is connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains, or may contain, contaminated water, sewage, or other waste or liquid which would be capable of imparting contamination to the public or semipublic supply as a result of back-flow. (2) "By -Pass"- A by-pass is a physical arrangement whereby water may be diverted around any feature of the puri- fication process of a public water supply. (3) "Emergency Intake"- An emergency intake is an intake or other device capable of introducing water into the public water supply system from a source,of supply which, because of its unsafe characteristics, has not been approved for drinking and culinary purposes by the State Department of Health. .54.130 Cross-Connectiora„�rib'hlbited. All cross - connections as defined ii? .:54.170 "(1) 'whether or not such cross - connections are controlled by automatic devices, such as check - valves, or by hand operated mechanisms such as gate -valves or stop cocks, are hereby prohibited. Failure on the part of persons, firms, or corporations to discontinue the use of any and all cross -connections and to physically separate'such cross -connections will be sufficient cause for the discontinuance of the public water service to the premises on which the cross -connection exists. .54.190 Methods of Providing for Fire Protection. When water supplies, not approved for drinking and culinary purposes by the State Department of Health, are used or maintained, pub- lic water supplies shall be made available for fire protection by the following methods only: (1.) Construction of a pump sump or reservoir into which the city mains discharge with a free fall, equal to not less than two diameters of the discharge pipe above the maximum spill line of the pump sump or reservoir, with pumps serving the independent system by taking suction from the pump sump or reservoir and pumping directly into the fire protection system; or (2) An elevated tank or standpipe supplied at the top by a discharge from the city main with a free fall, equal to not less than two diameters of -the discharge pipe above the maximum spill line of the elevated tank or standpipe. Such tank or standpipe may then be con- nected to the fire protection system; or (3) Installation of a "swing -connection” designed and operated in such a manner that when the private source is serving the independent system the public supply is completely severed, and when the public source is serving the independent system the private supply is completely severed; or (4) Two independent systems of piping without any con- nection whatsoever, one being supplied from the public system and the other from the independent water supply. .54.200 By -Passes Prohibited or Approved. No by-pass shall be established or maintained whereby water may be di- verted around any feature of a purification process of a I pubiid water' supply system, provided that with the specific approval of the State Department of Health, by-passes may be permitted around primary sedimentation basins, aerators or mixing chambers. .54.210 Emergency Intakes Prohibited. No emergency intake as defined in .54.170 (3) shall be established or maintained in connection with a public water supply system.

(d) The owner of the utility has instructed its proper operating officers and employees to add fluorine ion as apecifically authorized by the owner after approval of the State Department of Health. (4) Application of a fluorine compound - (a) The application of a fluorine compound shall be made through accurate feeding equipment. Either gravimetric or volumetric dry -feed equipment or positive -displacement liquid -feed equipment with an accuracy within 5 per cent is required. (b) Special precautions shall be taken to protect the operators from inhaling a fluorine compound dust when charging the hoppers of the feeders. Dry feeders must be equipped with dust collectors con- sisting of bag filters operating under positive air pressure and vented to the outside air. Each operator who handles a fluorine compound shall be provided with his individual toxic -dust respirator to be used only when handling the chemical. When liquid -feed equipment is used, at least two solu- tion tanks must be available for the preparation and storage of a fluorine compound solution. (c) The final minimum concentration of fluoride ion in the water supply shall be 0.7 p. p. m. and the maximum concentration 1.5 p. p. m. (5) Control - (a) Laboratory analysis and control shall follow specific instructions from the State Department of Health. (b) Samples must be taken before and after fluorida- tion and from one or more points in the distribu- tion system and at intervals as specified by the State Department of Health. (c) The method of determining the fluoride ion content of the water shall be specified by the State Department of Health. (d) The results of all chemical tests shall be recorded on forms approved by the State Department of Health and by the legal counsel of the water utility.

Operation of Public Water Supp'l'ie*s', .54.060 Quality':• No water shall be provided or rendered available for use to the public..for-drinking or domestic use which is of unsatisfactory sanitary 'quality and is not approved by the State Department-of Health. The sanitary quality shall be determined by the bacterio- logical, chemical, and physical standards as published by the U. S. Public Health Service, and contained in "Public Health Service Drinking Water Standards, 1946." The following are the bacteriological, physical and chemical requirements contained in these standards and are quoted for reference as follows: "3.2 Application - Applications 3.21 and 3.22 given below shall govern when ten milliliter (10 ml.) portions are used and applications 3.23 and 3.24 will govern when one hundred milliliter (100 ml.) portions are used.## 113.21. Of all the standard ten milliliter (10 ml.) portions examined per month in accordance with the speci- fied procedure, not more than ten (10) per cent shall show the presence of organisms of the coliform group. 113.22. Occasionally three (3) or more of the five (5) equal ten milliliter (10 ml.) portions constituting a single standard sample may show the presence of organisms of the coliform group, provided that this shall not be allowable if it occurs in consecutive samples or in more than: (a) Five (5) per cent of the standard samples when twenty (20) or more samples have been examined per month. (b) One (1) standard sample when less than twenty (20) samples have been examined per month. "Provided further, That when three or more of the five equal ten milliliter (10 ml.) portions constituting a single standard sample show the presence of organisms of the coliform group, daily samples from the same sampling point shall be collected promptly and examined until the results obtained from at least two consecutive samples show the water to be of satisfactory quality. #It is to be understood that in the examination of any water supply the series of samples for any one month must conform to both of the above requirements, either 3.21 and 3.22 or 3.23 and 3.24. 113.23. of all the standard one hundred milliliter (100 ml.) portions examined per month in accordance with the specified procedure, riot more than sixty (60) per cent shall show the presence of organisms of the coliform group. "3.24. occasionally all of the five (5) equal one hundred milliliter (100 ml.) portions constituting a single standard sample may show the presence of organisms of the coliform group,. provided that this shall not be allowable if it occurs in consecutive samples or in more than: (a) Twenty (20) per cent of the standard samples when five (5) or more samples have been examined per month. (b) one (1) standard sample when less than five (5) samples have been examined per month. "Provided further, That when all five of the standard one hundred milliliter (100 ml.) portions constitut- ing a single standard sample show the presence of organisms of the coliform group, daily samples from the same sampling point shall be collected promptly and examined until the results obtained from at least two consecutive samples show the water to be of satisfactory quality. "4.1. Physical characteristics. The turbidity of the water shall not exceed 10 p. p. m. (silica scale), nor shall the color exceed 20 (platinum cobalt scale). The water shall have no objectionable taste or odor. "4.2. Chemical characteristics. The water shall not contain an excessive amount of soluble mineral substance, nor excessive amounts of any chemicals employed in treatment. Under ordinary circumstances, the analytical evidence that the water satisfies the physical and chemical standards given in sections 4.1 and.4.21 and simple evidence that it is acceptable for taste and-odor will be sufficient for certification with respect to physical and chemical characteristics. "4.21. The presence of lead (Pb) in excess of 0.1 p. p. m., of fluoride in excess of 1.5 p. p. m., of arsenic in excess of 0.05 p. p. m., of selenium in excess of 0.05 p. p. m., of hexavalent chromium in excess of 0.05 p. p. m., shall constitute grounds for rejection of the supply. "These limits are given in parts per million by weight. Salts of barium hexavalent chromium, heavy metal glucosides, or other substances with deleterious physiological effects shall not be added to the system for water treatment purposes. "Ordinarily analysis for;,:these substances need be made only semiannually. If, however, there is some presumption of unfitness because of these elements, periodic determina- tion for the element in question should be made more frequently. 114.22. The following chemical substances which may be present in natural or treated waters should preferably not occur in excess of the following concentrations where other more suitable supplies are available in the judgment of the certifying authority.
