The paper examines the presence of arsenic in drinking water supplies and discusses the health effects. Information is presented on the source of arsenic, the method in which sediments remove arsenic from the surface water, and the processes by which arsenic can be released from the sediments back into the water. Water treatment practices related to arsenic removal from water are discussed. Arsenic levels in the Regina/Moose Jaw water distribution system are presented, along with an examination of the factors that may release arsenic held in the sediments in Buffalo Pounds Lake, the source of water supply for Regina and Moose Jaw. Based on the analysis of data, the possibility of reaching enhanced arsenic levels in Buffalo Pounds Lake through transfer from sediments is low; however, regular monitoring of arsenic in the lake water and distribution system is advisable.
