UVOST or MIP?

UVOST and MIP are not equivalent, and each has a role to play. Dakota offers both technologies as services since they apply to distinctly different forms of contamination. Most UVOST and MIP technicians report that they prefer to operate UVOST over MIP since there are far fewer variables and less maintenance. In practice the MIP systems requires a greater amount of expertise on the part of the provider.

Image of equipmentUVOST

  • Designed specifically for NAPLs containing PAHs (source term)

  • Smooth and hard sapphire window is slick like Teflon - resists dragging NAPL down or smearing 

  • Nearly instantaneous rise/fall - and 100% reversible response UVOST does NOT see any useful levels of response to dissolved phase PAHs or VOCs 

  • UVOST shows intimate detail of NAPL distribution (relative to MIP) 

  • UVOST provides readily interpreted spectral information in real time 

  • UVOST is blind to halogenated DNAPL - unless it was used to degrease PAHs

MIP

  • Specifically designed for VOCs

  • Encountering NAPL's sticky semi-VOCs often cause transfer line/carryover problems

  • Difficult to find bottom of NAPL due to carryover and resulting lag time

  • Logs require more experience and expertise to interpret (compared to LIF)
