Environmental Sampling and Analysis: A Laboratory Course for 21st Century Environmental Engineers

环境工程正在从一个主要关注市政供水，废水处理过程和工业废水排放的管道末端处理的领域发展到一个更广泛的关注领域。这一领域现在比以往任何时候都更加关注空气污染问题，而且在工艺一级减少污染也补充了对工业废物的最终处理心态。我们的教育本科生在环境工程需要改变，以反映在该领域的这些进步。 该项目调整和更新现有出版材料中的水化学方法和实验室练习，这些方法和练习以前在缅因州大学和密歇根大学实施过。 该实施将增加对其他介质（空气，土壤）测量的考虑，并增加更多的实际工程经验，以提高学生的学习。我们的本科课程包括环境采样和分析课程。多年来，这门课程基本上保持不变，这是一门强大的实验室课程，致力于学习城市饮用水和废水处理中常见成分的标准测量技术。测量技术的重点一直放在手工、湿化学分析方法上。 本课程的目的是：（i）增进学生对制造过程与环境保护之间关系的了解;（ii）扩大样品的种类，包括空气和土壤样品;（iii）增进学生对环境分析的现代仪器方法的了解。本课程的修订需要大量的人力和财力资源。四名教员，其中三人以前教过这门课，参与，并已组装了三个外部教员的审查小组。为了实现这些目标，将购买新设备。 为这门课开发的材料正在广泛传播，主要是通过环境工程和科学教授协会，一个有着分享实验室课程资源历史的组织。

Environmental engineering is evolving from a field primarily concerned with municipal water supply, wastewater treatment processes, and end-of-pipe treatment of industrial wastewater discharges to one with broader concerns. The field now encompasses air pollution concerns more than at any previous time and the end-of-pipe mentality for industrial wastes is being supplemented by pollution reduction at the process level. Our education of undergraduate students in environmental engineering needs to change to reflect these advances in the field. This project adapts and updates the water chemistry approach and laboratory exercises available in existing published materials and which had been implemented previously at the University of Maine and University of Michigan. This implementation will add the consideration of measurements in other media (air, soil), and add more practical engineering experiences to enhance student learning.Our undergraduate curriculum includes a class on Environmental Sampling and Analysis. For many years, this class has remained essentially unchanged-a strong laboratory class devoted to learning the standard measurement techniques for the common constituents of concern in municipal drinking water and wastewater treatment. The emphasis on measurement techniques has been on manual, wet chemistry methods of analysis. This class is being revised to (i) improve the students' understanding of the relationship between manufacturing processes and environmental protection, (ii) broaden the type of samples to include air and soil samples, and (iii) enhance the student's understanding of modern instrumental methods of environmental analysis.The revamping of this course requires a substantial commitment of human and financial resources. Four faculty members, three of whom have previously taught this class, are involved, and a review team of three external faculty members has been assembled. New equipment is to being purchased to accomplish the objectives. The materials developed for this class are being disseminated broadly, primarily through the Association of Environmental Engineering and Science Professors, an organization with a history of sharing resources for laboratory-based courses.
