Passive Diffusion Sampler:

    Case Studies & Technical Papers

• Bunnell-Lammons Engineering Study (1998) - Report produced by Andrew Alexander and Thomas Lammons titled "Field Trial of a New Commercially Available Diffusive Ground-Water Sampler". (Equilibrator introduced in study)

• McClellan Air Force Base (2001) - A recent study that compares cost, ease of use, and analytical results of samples collected by diffusion sampling and low-flow methods. (Equilibrator shown effective)

• USGS/EPA Guidance Document (2001) - Federal and State Agencies publish a Guidance Document for the use of Passive Diffusion Sampling.

• ITRC Final Report (2002) - Inter-State Technical Regulatory Council publishes "Recommendations on the Use of Polyethylene Diffusion Bag Samplers for Long Term Monitoring of Volatile Organic Compounds in Groundwater".

• ITRC Tech-Reg Document (2004) - Inter-State Technical Regulatory Council publishes "Technical and Regulatory Guidance for Using Polyethylene Diffusion Bag Samplers to Monitor Volatile Organic Compounds in Groundwater." This is an aid to regulators and users to determine the applications and use of PDBs.
