Dakota Technologies, Inc.

Dakota Technologies (Dakota) provides state-of-the-art services for hazardous waste site investigations, specializing in the rapid site assessment of subsurface LNAPL and multi-component DNAPL. Incorporated in 1993, Dakota has an experienced staff with over 100 years of combined experience in developing and deploying direct push screening tools for site investigations. Chlorinated solvents and petroleum hydrocarbons have contaminated subsurface soils and groundwater at thousands of sites all over the world. Traditional methods of determining the presence and extent of light non-aqueous phase liquid (LNAPL) and dense non-aqueous phase liquid (DNAPL) contamination are time consuming and costly, and may not be able to differentiate between contaminant phases. Laser-induced fluorescence (LIF) employs laser light to excite fluorescent molecules contained in the vast majority of hazardous NAPLs including petroleum fuels/oils, coal tars and creosotes.
