Notice of Blasting

Blasting for the Exeter Wastewater Treatment Facility at 13 Newfields Rd will be starting the week of August 7th, 2017.  Blasting is used daily in construction throughout the world.  It is the most effective method of breaking rock.

Portable seismographs will be used to measure and record the ground vibrations and air pressures.  This information is available and will be part of the project files.

The small air pulses that are generated by blasting operations may cause loose windows and loose doors to rattle loudly enough to be heard if you are standing nearby.  Also, ground vibrations will sometimes be heard or felt, if you live near the work area.  These effects are being monitored and recorded, and will be kept well below the safe guidelines recommended by the federal government for occupied residences.
