Intrusive investigations follow on from the Desktop Study. This is when we physically carry out soil sampling and soil testing.

This allows soil sampling to be carried out to determine the level of contamination present. The scope must be based on the findings of the desktop study. However, there is much more to it than just sampling soils! It allows other data to be gathered such as soils and rock type – which must be logged properly, observations of contaminants, depth to water etc. Monitoring wells may also be installed to measure groundwater depth, take water samples or measure gases in the soil.

What does an intrusive investigation involve?

An intrusive investigation also referred to as soil sampling, soil testing etc is more complex than simply putting soil into a jar or a bag! It is essential that it is carried out in the correct manner if the findings are to be accepted by regulators. We can guide you smoothly though this stage. The method and scope will depend on the findings of the desk top study. It can vary from a simple exercise involving hand sampling of shallow soils to investigations to assess risks to groundwater and from landfill gas.

How much does it cost?

This can vary tremendously depending on what is actually required. This will largely be determined by the findings of the desk top study. We normally liaise with the regulators in advance to establish what they are expecting meaning that we provide a report that covers what is required. We will give you an honest appraisal of what is required and what therealistic costs are. Of course, there are some situations where unexpected conditions are encountered that may require further work, but we will keep you appraised of this should it occur.

We have many years of experience in working on a wide variety of sites throughout the UK.
