PM 661 is a lecture/laboratory/field practicum covering sampling and analysis techniques for Occupational and Environmental assessment and monitoring. The laboratory experiments are intended to simulate typical measurement situations and to provide a basis for selection of sampling techniques and critical evaluation of laboratory results. The concepts common to each type of analysis and sampling method are these: (1) the identification of situations where this is appropriate; (2) the limitations inherent in the method (and what specific factors in the sampling situation might prevent accurate application of that approach); (3) the use of quality control procedures in sampling and analysis to verify the reliability and accuracy of the results; (4) correct expression of the results in terms applicable to occupational standards. One Red Mile building project and field sampling projects will allow the class to design, implement, and evaluate sampling results as well as prepare formal reports of the projects.
