Identify contamination sources

We specialise in investigating hydrocarbon-contaminated sites, particularly those with NAPLs (non-aqueous phase liquids) derived from heating oils. Our approach thoroughly identifies contamination sources and accurately measures the extent of pollution, helping you make informed decisions about site remediation and future development.

Our monitoring process

  1. Exploratory holes
  • Drilled to confirm or rule out suspected contamination.
  • Standpipes installed for in-situ groundwater sampling and monitoring.
  1. Oil/water interface probe
  • Determines the thickness of NAPLs within the standpipe.
  • Utilises a precision float to detect the NAPL’s surface and a conductive probe to identify the groundwater interface.
