| Use: | Sampling for vertical distribution of volatile ground water constituents. Samplers are used in both fixed and portable (see Section 3.5.2) configurations. |
Description:
Sampling occurs passively through natural diffusion of ground water so no pumping or displacement of water in involved (purging is not required).
Analytes:
| 1. Non-Halogenated VOCs | 3. Halogenated VOCs |
Media:
| Soil: | Ground Water: | Surface Water: | Gas/Air: |
| Not Applicable | MINIMUM | Not Applicable | MINIMUM |
| Maximum Depth: | Greater than 100 feet. |
| Production Rate: | Sample is available after a short amount of time. |
| Investigation Derived Waste Volume: | Small volume of waste. |
| Technology Status: | Commercially available technology with moderate field experience. |
| Certification/Verification: | Technology has not participated in CalEPA certification and/or CSCT verification program. |
| Relative Cost per Sample: | Least expensive. |
Limitations:
ASTM Standards/EPA Methods:
No applicable ASTM standards or EPA methods are cited for this technology.
