Arsenic

Arsenic in drinking water has been making headlines lately.

You may have seen some articles with the words “poison” and “toxic” in reference to arsenic. A recent USGS press release on a study they completed in 2011 focused on arsenic and other contaminant levels in New England bed rock wells caused a stir. Coincidently, ongoing research into the health effects of arsenic in drinking water has also been making headlines. What’s it all about? Keep reading for more information. What is Arsenic?

Arsenic (As) is a naturally occurring contaminant in drinking water originating from rock and soil deposits containing arsenic. The presence of arsenic can also result from human activities such as use of pesticides or glass and electronic production wastes. It is generally understood that most of the arsenic occurring in New England drinking water wells is associated with naturally occurring bedrock deposits. 

 

CEI Innovations

Engineers at CEI developed a treatment prediction model to assist the operators in determining the chemical feed dosages. Use the following link to find out more information about a treatment prediction model developed for a New England water treatment facility receiving water from multiple bedrock wells with water containing arsenic, iron, manganese and radon.

Water Treatment Chemical Feed Prediction Model

CEI developed a paper summarizing the information presented on this website, including methods of treatment for arsenic in drinking water.
