Progress Update on Mill River Dredging
The CT Department of Energy and Environmental Protection together with TRC, the firm conducting the cleanup work for Exide, has just released the June update on the Mill River cleanup project in Fairfield, Connecticut.
The contractor is currently in the process of dredging, dewatering the sediment, treating the filtrate water from the dewatering process, and discharging treated water back to the Mill River. All of the sediment dewatering and water treatment work is occurring at the facility on Exide’s property at 2190 Post Road in Fairfield.
During the May, the crews working on the project conducted additional dredging operations in Area III. Also, the turbidity meters (yellow buoys with solar panels), turbidity curtains (floating yellow items), and the large orange pipeline that conveys sediment to the Exide property were moved as dredging progressed in Areas III and I.
In June TRC will conduct the following activities:
- Continue dredging in Area I. Once this Area is complete, dredging will begin in Area II – the portion of the Mill River between the Metro North railroad bridge and Post Road bridge. The earliest dredging is anticipated to begin in Area II is during the last week of June;
- The turbidity meters (yellow buoys with solar panels), turbidity curtains (floating yellow items), and the large orange pipeline that conveys sediment to the Exide property will be moved as dredging progresses;
- Dewatering of sediment and treatment of filtrate will continue at Exide’s property;
- Monitoring and sampling will continue, as required by CT DEEP.
