Summary:Long recognized as a toxic element, arsenic has been linked to skin, bladder, and other cancers [1]. In an effort to protect human health, the U.S. EPA recently has lowered the arsenic drinking water standard from 50 to 10 mg/L. The tightening of the standard has encouraged federal, state, and local agencies to more closely examine water supplies for potential contamination with even trace amounts of arsenic. Because the processes that control arsenic behavior are often complex and interrelated, a combination of laboratory, field, and modeling analyses must be designed to provide a comprehensive protocol for evaluating the source, mobilization, and migration of arsenic.
