All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this article shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater," published by the American Public Health Association, and shall be determined at the sampling station provided, or upon suitable samples taken at said sampling station. Not less than three (3) copies of the latest edition of said volume shall be kept on file in the office of the city clerk for use and examination by the public. In the event that no special sampling station has been required, the sampling station shall be considered to be the nearest downstream manhole in the public sewer from the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property. (The particular analyses involved will determine whether a twenty-four hour composite of all outfalls of a premises is appropriate or whether a grab sample should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from a twenty-four-hour composite of all outfalls whereas pH's are determined based upon periodic grab samples.)
