Contaminated Land Remediation

Contaminated Land Remediation
Our contaminated land team possess many years experience in the design,
management, supervision and verification of soil and groundwater remediation
solutions. We provide contaminated land consultancy for landowners, developers
and main contractors, dealing with issues ranging from isolated soil contamination
hot-spots to widespread groundwater contamination.
As dedicated contaminated land consultants, our views are not influenced by the
commercial interests that can result in remediation contractors favouring one
particular outcome, remedial option or overall strategy. Our impartiality ensures the
client’s best interest remain at the fore throughout the project lifecycle, and their
objectives are met without unnecessary expenditure.
Exactly what is ‘contaminated land’?
Contaminated land (as defined by Part 2A of the Environmental Protection Act
(1990)) is that which poses a risk to human health, property or the environment, or of
significant pollution of controlled waters. The overarching objective of any pragmatic
contaminated land remediation strategy should be to reduce such risks to acceptable
levels or ‘as low as reasonably possible’ with the best achievable balance of cost
and effectiveness.
Although a requirement for the remediation of contaminated land may be legally
enforced under Part 2A, the vast majority of brownfield land contamination is
identified and remediated as part of the redevelopment process. Planning Policy
Statement 23 (Planning and Pollution Control) is concerned with development and
building on contaminated land.
Crucially, contaminated land risk assessment should be based on the fitness for use
approach, meaning that the sensitivity of the current or proposed use of the site
should be reflected in the risk assessment and any subsequent remediation strategy.
This means that the total eradication (or even reduction to background
concentrations) of contaminants may not be necessary to ensure it is ‘fit for use’.
