HIGH RESOLUTION Site CHARACTERIsATION (HRSC) 

  • Membrane Interface Probe (MIP) - In-situ gas testing for VOC's.
  • Ultra Violet Optical Screening Tool (UVOST) - Detection of free phase (LNAPL) hydrocarbons through Laser induced florescence.
  • Hydraulic Profiling Tool (HPT) - Identification of preferential pathways through hydraulic conductivity and Electrical conductivity (EC)
  • High resolution data required to effectively prepare CSM for the effective remediation of contaminated soils and groundwater.
