A intrusive investigation service is available at Edge Enviro Services should evidence from the preliminary and supplementary investigations identify that a significant risk of significant harm exists within and around the site.

Following sampling plan approval an on-site investigation will be conducted in accordance with best practice in order to ascertain the extent of contamination on site. Borehole sampling, auger sampling and window sampling are just some of the techniques used to obtain samples from a potentially contaminated site; water and gas monitoring are also available.

Samples are sent to an accredited laboratory for analyses and are then critically analysed in relation to the environment, and human health, Soil Guideline Values (SGV’s) are used in the assessment of risk to human health.
