WET 215 - Water Quality Analysis And Wet InstrumentationCredits: 3
Investigates conventional water and wastewater laboratory test procedures, with particular emphasis on those analytical techniques that require an understanding and practical use of laboratory instrumentation. Water Quality Lab tests include BOD, TSS, temperature, DO, pH, conductivity, TDS, total and volatile solids, alkalinity, TRC, and others common to the daily operation of both drinking water and wastewater plants; includes discussions of basic stream ecology and applied environmental science principles. Instrumentation Lab includes the use of pH, millivolt and specific ion meters and probes and an introduction to Spectrophotometry, atomic absorption (AA), and gas chromatography/mass spectrometry (GC/MS). Includes field tours of municipal water and wastewater treatment facility labs and related field study discussions.
Prerequisite(s): READING LEVEL 2 and WRITING LEVEL 2 and MATH LEVEL 6 and WET 110 and WET 112 and CHM 105W or CHM 111 or permission of the instructor.
