Experts In Contaminated Land Remediation

We undertake consultancy and remediation work on a number of different contaminant types to include:

Heavy Metals / Mettalloids

Heavy Metals and metalloids (an element such as arsenic or antimony with properties in between those of metals and non-metals) are common soil and groundwater contaminants that present a risk to users if concentrations exceed acceptable risk-based concentrations.  Contamination by metals and metalloids is most often related to industrial sources or mining and mineral processing.


Hydrocarbons in whatever form are generally the most common contaminant that requires remediation due to their widespread occurrence and the risks they pose to human health and controlled waters. We often advise on Petroleum Hydrocarbon contamination such as Petroleum, Diesel, Kerosene and Lubricating Oils/Greases. In addition, we can work with heavier TPH compounds including PAHs such as those found in coal tar, heavy oils and creosotes.  Chlorinated Hydrocarbons such as those found in solvents, plastics and insecticides also fall within our remit.

Inorganics / Invasive Species

A large number of inorganic contaminants exist that can impact soils, groundwater and drinking water. Whilst there is a degree of overlap with the metalloids from earlier, our expertise also extends to other contaminants such as nitrates and sulphates.  An invasive species is a plant, fungus, or animal species that is not native to a specific location (an introduced species) and has a tendency to spread to a degree that can cause damage to the environment, human economy or human health.  Our environmental experts are experienced in the identifi­cation and management of such species.
