There are several analytical methods available to collect and measure carbonyls in indoor and ambient environments which range from the use of glass impingers to filter methods to solid-phase extraction (SPE) cartridges through both active and passive sampling techniques. Furthermore, in the past decade, passive sampling has ...
Two new research papers published in 2019, by an Australian research group led by David Poulsen, build on earlier work by McMillan et al (2014) and others in improving our understanding of the depth origin of water samples collected from long-screened and open boreholes. Background When sampling groundwater wells and open boreholes, many practitioners think no ...
Since passive groundwater sampling was introduced over 20 years ago, the reliable, cost-effective sampling collecting alternative to groundwater purging has gained wide acceptance by environmental regulators and consultants. ...

Passive sampling typically produces results that are comparable to purge sampling results in most wells. ...
About the Webinar Purging and sampling methods and protocols have evolved over the past thirty years, from 3-5 well volume purging to low-flow purging and sampling to “no purge” and passive sampling approaches. This webinar provides an overview of these various groundwater sampling methods and ...
Current research activities deal with the development and application of passive air sampling techniques, the use of deterministic models to quantify and assign sources of variability in the contaminant exposure observed in human and wildlife biomonitoring studies, and the quantification and graphical representation of the atmospheric phase distribution of ...
TITLE: Considerations For Use of Passive/No-Purge Groundwater Sampling SPEAKER: Sandy Britt, PG, CHG, ProHydro, Inc. ...
One of the keys to successful remediation of a contaminated property is effective groundwater sampling. A new ASTM standard will aid groundwater samplers by taking a look at three types of passive samplers and their advantages, disadvantages and limitations. The new standard is D7929, Guide for Selection of Passive Techniques for ...
In this webinar learn about environmental diagnostic applications of the passive microbial sampling tool, the bio-trap. Bio-traps collect active microbes from the sampled environment distinguishing organisms involved in current biotransformations from the microbial noise of any natural environment. ...
Lord also delivered a presentation titled: Overcoming the Technical Challenges of LDPE Passive Sampling for PAHs in Groundwater and Surface Water. The Maxxam Award is presented annually to a scientist who has made a distinguished contribution to the field of analytical chemistry while working in Canada; it is presented each year as part of the Canadian Chemistry ...
A proposed new ASTM International standard will link easy to use, cost-effective and nonintrusive passive sampling with concentration data to measure vapor intrusion. WK40037, Guide for Determining Concentration Values from Groundwater, Air and Soil Gas Using Adsorbent-Based, Passive Samplers, is being developed by Subcommittee D18.21 on ...
Diffusion tubes are an excellent, low-cost sampling method allowing pollution over wide areas to be efficiently monitored for a long time period – each exposure period is usually 2-4 weeks. ...
Data generated from passive soil gas sampling are semi-quantitative and are dependent on numerous factors both within and outside the control of the sampling personnel. ...
If warranted by the results of the sampling data, EPA may undertake additional sampling and/or mitigate exposure to contaminants through indoor air utilizing its emergency response authority. EPA will conduct groundwater sampling and analysis of samples from the existing well network during the week of October 24th. ...
