Overview
Arsenic is a naturally occurring element in the Earth’s crust. Most arsenic in drinking water comes from natural rock formations, especially those of volcanic origin. Arsenic is primarily a groundwater issue. The new federal Arsenic Rule lowered the arsenic maximum contaminant level (MCL) from 50 ppb to 10 ppb and requires existing sources to be in compliance with the new MCL by January 2006.
In this course, the student will learn about arsenic treatment occurrences and processes. The student will learn treatment design using oxidation/filtration, ion exchange, sorption, as well as waste disposal methods.
