Merrimack

In the fall of 2016, Saint-Gobain began work to connect homes in Merrimack whose wells had been impacted by PFOA to the municipal water lines of Merrimack Village District (MVD).

(This is a timeline of the project from October 2016 to August 2017. For updates on the project past August 2017, please visit the home page or look for the “Merrimack” category in the drop-down menu to the right.)

August 2017 – A total of 16 properties have been connected: 3 properties on Back River Road; 3 properties on Woodhaven Circle; 2 properties on Bedford Road; 7 on Daniel Webster Highway; and 1 on Maple Street. Planned connections in the works/being scheduled: 1 property on Woodhaven Circle; 1 property on Maple Street that requires a short extension; and 1 property on Daniel Webster Highway where an easement is needed. NHDES has requested that Saint-Gobain connect the following properties to Merrimack Village District water. Saint-Gobain is disputing responsibility for groundwater contamination in this area: 3 properties on Wire Road; 1 property on Paige Drive; 1 property on Bedford Road; 1 property on Knollwood Drive.

May 25, 2017 – Two more water services have been installed. Several wells to the west of Saint-Gobain have tested above 70 ppt. NHDES has requested that Saint-Gobain connect these properties to MVD.

February 10, 2017 – Three more water services have been installed. Five more properties’ wells have tested over 70 ppt. NHDES requests that Saint-Gobain provide public water to these properties.

December 16, 2016 – Some Merrimack properties will need a Point-of-Use system installed if water service installation cannot be completed in 2016.

November 4, 2016 – Thirteen properties in Merrimack have been connected to public water. Saint-Gobain is moving forward with making connections at an additional seven properties with impacted wells.

October 2016 – Saint-Gabain notified NHDES that five properties in Merrimack had been connected to public water, and the company was moving forward with making connections at an additional 16 properties.

MVD Well Nos. 4 and 5


May 25, 2017 – Saint-Gobain’s consultants, Barr Engineering, completed their study around MVD wells 4 and 5. A copy of the report is available here.

January 13, 2017 – Saint-Gobain has offered to deliver a temporary granulated activated carbon (GAC) filtration system with new GAC. MVD and Saint Gobain need to finalize responsibility for installation, operation and maintenance of the temporary GAC filtration system.

December 16, 2016 – MVD and Saint-Gobain have an agreement in place for MVD to have their Engineer continue with Preliminary Engineering for implementation of a treatment solution. MVD’s Engineer is working through the preliminary engineering. MVD is slated to confirm at the Board meeting on Dec. 20, 2016, whether they want the temporary GAC filter unit from Hoosick Falls, NY as offered by Saint-Gobain. If so, Saint-Gobain will arrange delivery. It is expected to be available in late January.
