Because each study or survey may be different, much effort is needed to set up and equip the laboratory and schedule the required survey tests. For example, when the Technical Sup­ port Branch field team arrives at the study site, they will set up the mobile laboratory, prepare reagents and glassware, and run preliminary standard tests

to be certain that the methods and instruments are functioning properly. Region II maintains one Mobile Laboratory at Edison and one at Rochester ',hat are used on-site to monitor bacteriological changes, biological oxygen demand, pH, total suspended solids, and other time-sensitive tests. There is also an Air Mobile Laboratory at Edison containing instruments for the analysis of S 0 , NO>, oxidants, methane and nonmethane hydrocar­ bons, CO, and a tape sampler for particulates in air. The data is collected on a Wang 600 and reduced from the tape on a second Wang 600 for printout of hourly averages and other data on a typewriter. 2

Laboratory Work, Data, and Reports Field data is entered on the Field Data Sheet, which corresponds to a laboratory number attached to the test sample. Sample numbers are matched against the descriptors and parameters in the field, on receipt at the laboratory, and by each analyst. Preliminary reports are issued to the...
