Families complaining that their houses are shaking were told that it's due to an expansion at a nearby military firing range.
Altcar Training Camp has quashed fears raised by people living in the vicinity, that 'fracking has begun at the bottom of our gardens'.
Residents living in homes very near the camp in Hightown , told the ECHO that there is an 'incredible' amount of noise coming from the site.
One woman living on Mark Road said: "There is an incredible racket coming from the bottom of my garden, and I can see what looks like a giant fracking operation about 20 feet away.
"It's very noisy and there's a giant digging machine. The foundations are shaking."
Another resident compared the vibrations to a 'mini earthquake'.
But a spokeswoman for the military base has put their worries to bed.
What people are experiencing, according to the Reserve Forces’ & Cadets’ Association (RFCA), is actually due to piling work that has begun onsite.
The work is expected to last for the rest of this week, and possibly into next week, depending on ground conditions that are encountered.
The piling work will only take place during daytime hours Monday-Friday, evening and weekend work will not be required.
These works will form part of a ten-month project which will see North West RFCA headquarters staff move into a new two storey office building located near the main entrance of the camp.
A spokeswoman said: "The office will be a modern and eco-friendly building with an associated car park ; which will provide an enduring base for our ongoing work in support of the Reserve and Cadet forces in the region.
"The move comes as part of an ongoing project to relocate into a sustainable building for the future.
"The project is completely self-funded and will reduce the financial burden imposed on the association and freeing more resources to the benefit of the Reserve and Cadet estate in the region."
The site at Hightown has been used for training hundreds of thousands of soldiers, including those involved in two world wars.
The facility was founded when, under threat from invasion, the War Office called for Volunteer Rifle Corps to be set up.
In 1860 the 500 acres of land was sub let by Stodart Robert Clarke to Lieutenant Colonel Gladstone at a rent of £250 a year and later was rented directly from Lord Sefton.
The earliest record of cadets shooting there is in 1865.
All building work is expected to be completed by the end of July 2020.
