1. ANALYTICAL CHEMISTRY, INCLUDING TECHNIQUES, EQUIPMENT, AND PROCEDURES FOR INORGANIC AND ORGANIC ANALYSES-These questions test for knowledge of general principles of chemical analysis, including the various techniques used in the chemical analysis of both organic and inorganic materials, the operating principles and characteristics of the analytical equipment used, and laboratory safety.

2. ORGANIZATION AND INTERPRETATION OF DATA, INCLUDING ELEMENTARY STATISTICAL ANALYSIS AND QUALITY CONTROL-These questions test for knowledge of the various techniques used in data collection and analysis. Questions may include such areas as proper methods of collecting and organizing data, elementary statistical operations performed on data, and interpreting tabulated results properly.

3. PRINCIPLES AND APPLICATIONS OF PHYSICS AND CHEMISTRY RELATED TO THE TESTING OF BOTH TREATED AND UNTREATED WATER-These questions test for knowledge of the principles and practices of physics and chemistry as they relate to the characteristics of water, including such areas as water testing, sample preparation, and the methods, materials, and equipment used for measuring a variety of physical and chemical parameters; and water treatment processes as they relate to water chemistry and testing.

4. GENERAL LABORATORY PRACTICES, TECHNIQUES, AND EQUIPMENT-These questions test for knowledge of basic laboratory practices, techniques, and equipment, including such areas as proper and safe techniques in sample preparation and analysis; use and characteristics of laboratory supplies, equipment, and instrumentation; principles and practices of laboratory safety; preparation of solutions of various concentrations; and terminology and underlying scientific principles associated with laboratory work.

5. SUPERVISION-These questions test for knowledge of the principles and practices employed in planning, organizing, and controlling the activities of a work unit toward predetermined objectives. The concepts covered, usually in a situational question format, include such topics as assigning and reviewing work; evaluating performance; maintaining work standards; motivating and developing subordinates; implementing procedural change; increasing efficiency; and dealing with problems of absenteeism, morale, and discipline.

6. PRINCIPLES AND APPLICATIONS OF MICROBIOLOGY RELATED TO THE TESTING OF BOTH TREATED AND UNTREATED WATER-These questions test for knowledge of microbiology as it relates to water testing, including such areas as sample preservation and preparation for microbiological analysis; methods, materials, and equipment used in the culture and identification of microorganisms, including microscopy; characteristics and effects of microorganisms; and general principles of microbiology and water treatment.

7. TESTING METHODS FOR ASPHALT AND ITS INGREDIENTS, AND RELATED LABORATORY EQUIPMENT, TECHNIQUES, AND SAFETY PRACTICES-These questions test for knowledge of various asphalt and aggregate tests, laboratory practices, quality controls, safety related to these tests, and the evaluation of results.
