The Challenge

80% of the error and uncertainty, therefore the time and cost of site

assessment, cleanup, and long term resolution is directly attributable to a

lack of representative samples

Audience Poll


Have you previously used direct sensing tools? • Membrane Interface Probe (MIP) • Laser Induced Flourescence (LIF) • Hydraulic Profiling Tool (HPT) • Membrane Interface Probe-Hydraulic Profiling

Tool (MiHpt) • No


Integration of Multiple HRSC Tools


1. Isolate and

Refine the

Source Area

2. Determine pathways

of permeability

3. Sample to confirm mass and contaminant

ID and remediation parameters


Membrane Interface Probe (MIP) Quick Notes: - Volatile Organic Compounds (VOCs) - Vapor, Dissolved Phase, Sorbed Phase, some NAPL - Typical DL: 1 ppm fuel / 200 ppb solvent (can be lower with special procedures)

- Integrated Electrical Conductivity and/or Hydraulic Profiling Tool - Optional Heated Trunk Line - Matrix effects - Performance Test Required!

Sample LIF Log

Laser Induced Fluorescence (LIF) UltraViolet Optical Screening Tool®(UVOST®)

Quick Notes: - Responds to PAH containing compounds - Residual Phase Petroleum Hydrocarbons - Excellent mapping of NAPL - Matrix effects - Reference Emitter (RE) source test required

Compound Waveforms

Optical Spectroscopy:

- FOUR different frequency bands - Fluorescent light received from the down hole window - Lighter, shorter chain hydrocarbons blue-green - Heavier, longer chain hydrocarbons orange-red - Matrix effects - Reference Emitter (RE) source test required

Pneumatic Slug Test (PST)

Quick Notes: - Used to measure hydraulic conductivity “K” - Portable, manual tool kit - Pressurizes formation and then monitors formation recovery after releasing the pressure - Test performed in existing monitoring well or via direct push drive point - Development and condition of the well or drive point screen critical to the quality of the test

Comparison of 8 Effective K Measurements to 10 Conventional Pump Tests

Potentially Better and More Info For Lower Cost

Average K-Value calculated from Slug Test Results in 10 monitoring wells from the 11-14 meter screened interval 1.5 x 10-3 cm/sec compared to 2.6 x 10-3 cm/sec for HPT

• Consider the cost of well installation and pump tests. • Consider the challenge of isolating individual flow regions. • Consider the impact on site dynamics and remediation costs if you don’t.

Important Final Thoughts • LOE – Use a (Multiple) Lines of Evidence Approach (no one

tool, sampling methodology, or analytical method works in every soil and every situation)

• Measure the heterogenity - Local lithologic changes and local hydraulics control your outcome

• Match the correct detectors to the compounds of concern and know what you are measuring

• Always review performance test before going to the site

• Beware of the statisticians – trying to correlate sample + lab for specific compounds against qualitative screening tools is worse than going to Las Vegas

• Call for expert support prior to planning your field effort

One More Final Thought

It is far better to be approximately correct with a huge data set than precisely wrong with a limited data set.
