Arsenic in Drinking Water November 10, 2023 By Katelyn McLaughlin A-Z for Operators series, Compliance Monitoring, Drinking Water, Water Treatment arsenic, A-Z for Operators, compliance, free resources 0 Arsenic is a heavy metal and a regulated contaminant in drinking water and wastewater effluent. In 2001, under the Arsenic Rule, EPA adopted a lower standard for arsenic in drinking water of 10 parts per billion (ppb) which replaced the previous maximum contaminant level (MCL) of 50 ppb. Arsenic is a semi-metal element in the periodic table. It is odorless and tasteless. It can enter drinking water supplies from natural deposits in the earth or from agricultural and industrial practices.
