New Sensor for Detecting Petroleum Spills in the Subsurface

摘要

Dakota Technologies (USA) offers the UVOST®, a direct-push delivered sensor that allows rapid screening of most petroleum-based light non-aqueous phase liquids (LNAPLs). This tool uses laser-induced fluorescence (LIF) technology to immediately detect sub-surface contamination without having to draw samples or wait for lab results. The UVOST responds exclusively to source term NAPL, free of interference from dissolved phase hydrocarbons, and it is ideal for detecting fuels, lubricants, and crude oils. The system is designed for use with all direct-push platforms such as Geoprobe®, AMS PowerProbe®, and cone penetrometers.
