Laboratory

The laboratory sections will be self-directed, with the exception of training on some of the more advanced instruments. I will provide you with the equipment to measure a number of water quality parameters. You, as a group, will be responsible for developing a work plan to evaluate water quality at a field site, implement that plan, analyze the data, and develop a quantitative report on the water quality.

Chapters 9-33 deal with the theory and operation of environmental instrumentation. These chapters will be very beneficial to you as you develop your water quality sampling and analysis plan. In addition, these chapters will provide you with the information you need to discuss the various analysis techniques and approaches. I will not assign reading in these chapters, but will expect you to be familiar with the material as it applies to your laboratory work.

The laboratory section is focused on data analysis and designed to allow you to become familiar with basic laboratory techniques. It is not designed to train you to be an environmental analytical chemist. You should also become familiar with field sampling methods and field analytics. You will be required to develop your own work plan, implement that work plan, and write a comprehensive quantitative water quality analysis report. This type of work is similar to what you will do as environmental engineers, many times sending samples to analytic laboratories, but still responsible for data analysis and reporting.

The written laboratory reports are a significant portion of the laboratory experience. Organization, style, grammar, completeness, and appropriateness will be considered in the grading.

Grading:

This course is made of two distinct parts: 1) Class lectures and 2) laboratories. The goal of the lecture portion of the class is to help you develop chemistry skills which will be useful you as you practice environmental engineering

A presentation will be developed on some aspect of environmental chemistry approved by the instructor. It will be presented (PowerPoint or overheads) in a 10-minute event on the last day of lab.

Grades will be based on the following criteria:

1^st Midterm Exam 15%

2^nd Midterm Exam 15%

Intermediate Lab Reports 10%

Lab Water Quality Report 15%

Homework 20%

Presentation 5%

Final Exam 20%

Please note that the laboratory can be a dangerous place if proper safety procedures are not followed. For this reason, safety instructions will be strictly enforced. A list of laboratory rules and procedures will be distributed before lab work begins.

LABORATORY SCHEDULE

With a few exceptions, the laboratory schedule will be determined by your individual teams working with the rest of the class.

Date	Ideas	Reading
Sept 4	Introduction	Chap 9
Sept 6	Semester Goals and Requirements	Chap 10
Sept 11	Basic Concepts	Chap 11
Sept 13	Instruments	Chap 12
Sept 18	DRAFT Work Plan – DUE
	Work Plan needs coordination across groups
TBD	GC/MS – probably 3 lab periods
TBD	Purge and Trap – probably 2 lab periods
Dec 4	Presentations -
Dec 6	Presentations -
Dec 13	Laboratory Final Report – Hand In

You will be required to write and hand in a weekly laboratory report. In some cases, this will be a status report. In other cases, it will be a laboratory report on the measurements you performed and results you found that week. These will be chapters in the final laboratory report.

I will (or you will) divide the class into 2 or 3 student teams for this work. Each team will need to supply their data to the other teams so that a statistical analysis of the results can be performed.
