CV 322 - Environmental Laboratory2 lecture hours 2 lab hours 3 credits
Course Description
Emphasizes laboratory methods and interpretation of laboratory results for the physical, chemical, and biological analyses of environmental samples, including those used to characterize water and wastewater treatment operations, surface water systems, and soil and ground water (prereq: CH 201 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Describe several of the more important water quality parameters used to characterize water quality with respect to potable water and municipal wastewater
- Conduct experiments and analyze and interpret the experimental data to determine values of selected water quality parameters following Standard Methods procedures
- Explain the environmental significance of each of the water quality parameters studied
