| Contaminated Land - A pragmatic
view |
| by DAN CLOWATER, Senior Consultant
and JIM GOTT, Associate Director, CRA (EUROPE) |
|
Let’s face it, in the majority of cases, the
remediation of contaminated land shouldn’t be
complicated; so why are views so widely varied?
Simply put: risk!
Potential environmental risk on any site is important
in the eyes of a variety of stakeholders, including
the site owner, the potential developer, the chosen
consultant/contractor and the site regulator.
Unfortunately, it is rare for all parties to have
the same understanding of the risks and to have
the same views on acceptable and unacceptable
risk levels...

| Stakeholder liaison: A case study
from Cornwall |
| by DR STEVE HOBBS of Enviros |
| Contaminated land can be a very emotive
issue affecting people's lives in many ways. Technical
issues are only one facet of a complex interplay
which may also include financial, political, regulatory
and social aspects with resolution of conflicting
opinions being a key issue. At RAF Portreath many
of these factors required consideration to deal
with the contaminated land legacy from former Chemical
Defence Establishment (CDE) Nancekuke. Addressing
the relationships, interactions and requirements
of all stakeholders at an early stage was essential
to the success of the project... |

| Groundwater Remediation of a Chalk
Aquifer |
| Bilfinger Berger is currently
undertaking the remediation of land contaminated
with Chlorinated Solvents and Hydrocarbons on a
site on the South Coast of England. |
| Chlorinated Solvents to degrease
and clean aircraft engines at a facility on the
south coast of England had lead to losses of the
cleaning agent into the groundwater. In addition,
a separate loss of kerosene fuel had occurred. Voluntary
remedial works were already in place to address
both the kerosene loss which had impacted a shallow
gravel aquifer at 2-4 metres below ground level
and the deeper chalk aquifer (12m bgl) contaminated
with solvents... |

Japanese Knotweed continues to invade the UK
causing costly and lengthy problems for landowners
and developers alike. Left to its own devises
it will displace native species causing, in some
instances, extensive damage to property growing
through concrete and tarmac.
The legal position is that Japanese Knotweed
is just one of the plants listed within the Wildlife
& Countryside Act 1981 for which it is a criminal
offence to allow or otherwise cause to grow in
the wild...

| SOILUTIONS |
| BACKGROUND - Soilutions were approached
to devise and implement an innovative technique
to address contamination issues resulting from former
military operations at Stornoway Airport on the
Isle of Lewis. THE PROBLEM - A redundant NATO jet
fuel pipeline contained an unknown amount of water
grossly contaminated with residual kerosene. The
pipeline, which is encased within concrete below
ground, runs from a purpose-built fuel jetty across
machair for 1.5km to an underground fuel bunker... |

(EIA) |
| Emerging local and regional planning
policy has identified land near the confluence of
the River Thames and River Lea in east London as
an opportunity for high-density residential-led
mixed-use redevelopment. |
| Gasworks Redevelopment in West
London |
| The site, formerly part of the National
Grid Gas property portfolio, had already been investigated
by Waterman Environmental under its term contract.
Waterman Environmental was then selected by the
developer as retained consultant because of the

environmental management and development engineering
