Intended Audience and Benefit

This course is intended for environmental engineers, hydrologic\hydraulic engineers, geo-hydrologists, municipal engineers, project managers, and any persons working in civil engineering field or anyone with an interest in Removal of Arsenic from Drinking Water Supplies by Iron Removal Process.

Course Introduction

Arsenic is a common occurring contaminant that can be found in arsenic-bearing rocks and soils. Arsenic can also be found in pesticide runoff, glass and electronics production waste. Arsenic can be transported by erosion to natural waters and subsequently to water treatment plants. The removal or arsenic can be done effectively using the iron removal process.

Course Content

The Safe Drinking Water Act (SDWA) of 1974 mandated that the United States Environmental Protection Agency (USEPA) identify and regulate drinking water contaminants that may have an adverse effect on the public. In 2003 the USEPA mandated that the Maximum contaminant level (MCL) of arsenic to be at or below 0.010 mg/L. This course will present the removal of arsenic from drinking water using the Iron removal process.
