There are a number of treatment techniques that can effectively remove arsenic from drinking water. It is essential for utilities that are in the process of selecting an arsenic removal treatment technology to also identify the types of residuals that would be generated, their expected arsenic concentrations, and pre-treatment strategies that would be required prior to final disposal. This document provides utility guidelines for disposal of residuals containing elevated concentrations of arsenic.Originally published by AwwaRF for its subscribers in 2003 This publication can be purchased and downloaded via Pay Per View on Water Intelligence Online - click on the Pay Per View icon below

The reduced drinking water arsenic MCL of 10 micro grams per litre will require many utilities to remove more arsenic from their source water, thereby concentrating it in their residuals. Because arsenic removal is sensitive to both the pH and the oxidation state, any process that changes pH or results in a reducing environment may release arsenic from the solid phase. Management of arsenic-laden residuals is an important issue due to the potential re-release of arsenic into the environment. This report identifies factors that influence arsenic release and provides a decision tree for use by utilities with arsenic-laden residuals.

The book provides state-of-the-art information on removal, recovery, treatment, and disposal of mercury and arsenic wastes, based on a workshop held in Alexandria, Virginia in August 1992. The goals of the workshop were: 1) to examine the fundamentals and analytical issues related to mercury and arsenic compounds; 2) to disseminate information on the state of practice of source reductiontechnologies that recover or remove mercury and arsenic from industrial wastes'and recycling or reuse processes; and 3) to discuss existing and emerging technologies that treat industrial wastes or contaminated soil and water, and the storage and disposal of treated wastes. The book is presented in two parts Mercury and Arsenic and contains extended summaries of papers presented at the workshop. The areas covered are fundamentals, analytical techniques/characterization; removal, recovery, and reuse; and treatment, storage, and disposal.

The authoritative articles in this book represent the state-of-the-art in arsenic research. Arsenic experts from around the world - participants in the Fifth International Conference on Arsenic Exposure and Health Effects organized by the Society for Environmental Geochemistry and Health in 2002 - present their critical findings. The authors share their latest arsenic research findings in Occurrence, Epidemiology, Biomarkers and Animal Models, Mode of Action, Mode of Action, Risk Estimation, Intervention and Medical Treatment, and Water Treatment and Remediation. As in past conferences, the first report of elevated arsenic exposures in a new country was given. The Conference introduced the finding of arsenic contamination in Nepal and updates of the arsenic problems in Bangladesh, India, Vietnam are included. A vital contribution to arsenic study and policy making, this volume examines the global impact of the toxin and discusses arsenic in the environment, mechanisms of arsenic metabolism and carcinogenesis, water treatment technology, and medical care. Arsenic Exposure and Health Effects V offers informed, challenging insights into a highly important and controversial topic.

Due to California's stringent hazardous waste (HW) classification regulations, high capacity adsorptive media (AM) used for the removal of arsenic from potable water are likely to be classified as HW if operated to breakthrough. An alternative is to prematurely shorten the AM life, avoiding generation of HW. A user friendly model was developed to examine the impact of the waste classification of spent AM on the replacement and disposal costs for arsenic removal systems. The model was used to examine the effects of influent arsenic concentration, AM cost, HW transport distance, and disposal fee on total costs associated with both generation of non-HW and HW for a range of AM exhaustion capacities for arsenic. Waste transport and disposal were found to be only 3.2 and 14.3 percent of the cost of media replacement for a system generating non-HW and HW respectively. As a result, large increases (e.g., tenfold) in HW transport and disposal costs had a relatively small effect on the range of arsenic exhaustion capacities of AM over which non-HW generation was less costly. The only realistic scenario in which non-HW generation would become less costly for a large range of exhaustion capacities would be a large (e.g., tenfold) decrease in media cost.
