Issued 10/22/2013 Administrative Order (AO) to Village of Danvers for failure of its public water system to comply with the Arsenic MCL. The AO requires Danvers to come into compliance with the Arsenic MCL by no later than 12/31/2016; submit quarterly progress reports to U.S. EPA; continue to monitor for Arsenic quarterly until U.S. EPA notifies in writing otherwise; and provide public notice every three months as long as the violation persists. On 6/19/2017, U.S EPA issued the Village of Danvers a letter terminating the AO because our records showed that the Village of Danvers fulfilled the terms of the AO by: constructing a new water treatment facility, collected four quarters of sampling results demonstrating compliance with the arsenic MCL, submitted a preliminary engineering report and quarterly progress reports to U.S. EPA, and provided public notice every three months as long as the violation persisted.
