MacIntosh & Tucker Wells Treatment Evaluation

The Town of Newmarket has been dealing with limited water supply since a decision was reached in 2005 not to upgrade or replace their surface Water Treatment Plant to meet more stringent water quality regulations. With its two gravel packed wells, the Bennett and Sewall Wells, the Town was not in compliance with NHDES source water capacity criteria which require meeting average day demand with the largest well out of service. In 2006, the Town initiated a search for bedrock aquifer groundwater supplies which resulted in development and permitting of the MacIntosh and Tucker Wells. In response to a directive by NHDES, the Town completed a Corrective Action Plan (CAP) indicating how the Town would increase its source water capacity. The CAP, which was submitted and accepted by NHDES in May of 2012, provided a proposed schedule for placing the MacIntosh Well, into service.
