Arsenic Treatment for Small Water Systems
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.
The student is expected to read and review the
material contained in Guidance Document: Arsenic Treatment For Small Water
Systems, DOH Pub #331-210 November 2005.
The student must take a
multiple-choice quiz consisting of sixteen (16) questions at the end of this course to earn PDH credits.
