Arsenic Removal

Arsenic is a naturally occurring chemical found in the earth's crust, but can be dangerous to humans when released into drinking water supplies when rocks, minerals, and soil erode.

One of today's hottest, and often controversial, topics in worldwide water regulations is arsenic in drinking water. Arsenic is a naturally occurring chemical found in the earth's crust, but can be dangerous to humans when released into drinking water supplies when rocks, minerals, and soil erode. Studies have linked long-term exposure to arsenic contamination with cancer and cardiovascular, pulmonary, immunological, neurological and endocrine effects. USEPA announced in January that the new arsenic standard of 10 ppb will require compliance by January 2006.

While many water systems do not detect arsenic in their drinking water above 10 ppb, geographic "hot spots" have systems that may have higher levels of arsenic than the predicted occurrence for that area. In the U.S., for example, about 3,000 (or 5.5 percent) of the nation's 54,000 community water systems (CWSs) and 1,100 (or 5.5 percent) of the 20,000 non-transient, non-community water systems (NTNCWSs) will need to take measures to lower arsenic in their drinking water. Nearly all of the affected systems serve less than 10,000 people.

So how do we treat systems affected by new regulations? Severn Trent Services' arsenic removal program incorporates a process and filter media that can be a lifeline for those feeling the pressures of regulatory compliance. The result of years of careful development, the SORB33 system – commercially proven since 1999 - reduces levels to less than 4 ppb. The simple and economical SORB 33® technology uses Bayoxide® E33 granular or Bayoxide® E33P pelletized, ferric oxide media, developed by LANXESS and produced for Severn Trent specifically for groundwater source drinking water adsorption. The Bayoxide® media are long-lasting and once exhausted can be sent to a non-hazardous landfill for disposal.
