Boo Hole landfill site
The former Boo Hole landfill site was designated as contaminated
land in April 2009. Although there was evidence of gas migrating
from the site, investigations did not identify the presence of gas
inside properties bordering the site where monitoring had been
undertaken.
Background
Boo Hole is located in Heywood between Bury New Road and Bury
Old Road, situated approximately 1.5km east of the M66, junction
2.
Site History
The 1890’s historical maps record a “Sand Pit” in the vicinity
of the present day Boo Hole Farm in the northwest corner of the
map. This sand pit was subsequently expanded up until the 1960’s.
Sometime after this the site became a landfill for domestic and
commercial wastes, tipping continued until the 1990’s when the site
was closed and landscaped.
Action taken
We were alerted the landfill was producing gas in 2002. Landfill
gas is produced from the natural breakdown of the infilled
material, in this case, wood, paper and other wastes and comprises
a number of gases, chiefly methane and carbon dioxide. We then
commissioned consultants to undertake investigations.
The investigations
The investigations involved:
- A record search over the type of wastes that went into the
site
- Installing boreholes so the ground gases could be
monitored
- Taking soil samples to analyse for contamination
- Risk assessments to assess the level of risk
The investigation concluded there was no risk to site users.

Work following determination
- Our application to DEFRA for funding to undertake the
remediation works at Boo Hole was successful and the works have now
been completed.
- A monitoring period has been completed that has demonstrated
the barrier is working as expected.
- The contaminated land register has now been altered to show the
former Boo Hole Landfill has now been remediated.
