6 SAMPLE ANALYSIS TOOLS for VOCs, SVOCS, and PESTICIDES

Use:

The free product sensor is designed to give an accurate measurement of liquids lighter than water.

Description:

A 1.5-inch (38-mm) diameter probe includes a highly visible light with audible signal to indicate the presence of water and light immiscible liquids.

Analytes:

11. TPH

Media:

Soil/Sediment	Water	Gas/Air
Not Applicable	BETTER	Not Applicable

Selectivity:	Technique measures a part of the compound.
Susceptibility to Interference:	Low.
Detection Limits :	500+ ppm (soil); 100+ ppm (water).
Turnaround Time per Sample:	Minutes.

Applicable To:

Screen/Identify	Characterize Concentration/Extent	Cleanup Performance	Long-Term Monitoring

Quantitative Data Capability:	Does not produce quantitative data.
Technology Status:	Commercially available and routinely used field technology.
Certification/Verification:	Technology has not participated in CalEPA certification and/or CSCT verification program.
Relative Cost per Analysis:	Least expensive.

Limitations:

Primarily for detecting analytes (gasoline, diesel) floating on top of an aquifer.

ASTM Standards/EPA Methods:

No applicable ASTM standards or EPA methods are cited for this technology.
