Samplers for Industrial-Waste Surveys Hubert S. Kline Industrial Hygiene Engineer, Frigidaire Division General Motors Corporation Dayton, Ohio In an industrial-waste survey program, a sampler may be defined as a device for obtaining a portion of the flowing waste for study. With modern-day direct-reading equipment it is possible to modify the definition of a sampler to include means for obtaining samples or indicating directly the chemical nature of the flowing waste. Thus, an indicating pH meter could well be classified as a sampling instru¬ ment. Inasmuch as flow is integrated so closely with samplying, this paper will include a brief review of methods and equipment for obtain¬ ing flow and pH data as well as samples for chemical analysis. As a composite example of the principles discussed, the paper concludes with a brief description of the sampling station used in connection with the Frigidaire industrial-waste control program. Flow Measurement Certain industrial plants rely more heavily than others on dilution of their plant effluents by the receiving body of water. Therefore, it is important that flow rates, both of the waste water and the receiv¬ ing stream, be definitely known. This is especially true during dry- weather flow periods when dilution may be greatly diminished. For¬ tunately some of our public agencies have established gaging stations on most of the heavily populated rivers and have available flow data which may be obtained upon request. Many of the state stream com¬ missions, conservancy districts, water resources boards, and private utilities along such bodies of water are likewise sources for this infor¬ mation. If stream-flow information is lacking in the area, it is then advisable for the industry to consider establishment of their own stream- flow gaging station. With the flow characteristics of the receiving stream at hand, it is rather simple for the particular industry to evalu¬ ate its own waste discharge rates in order to determine if stream standards can be or are being satisfied. 191
