Removal of Arsenic from Drinking Water Supplies by Iron Removal Process

Vincent D. Reynolds, MBA, PE

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.

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.

This course will provide the reader with the practical knowledge to remove Arsenic from Drinking Water Supplies by Iron Removal Process. Various types of oxidants used in the removal processes will be discussed, as well as capital and operating costs of water treatment facilities.

This course material is based on the document “Removal of Arsenic from Drinking Water Supplies by Iron Removal Process,” as published on the website of the United States Army Corps of Engineers.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
