Teflon fep Tubing for soil gas sampling
Suniu manufactures(in China) teflon fep tubing right for soil vapor sampling. By DTSC, teflon fep tubing is approved for soil gas sampling tubing. Our tube is without PFOA. It will be cleaned according to Class 6 of ISO146441(cleanroom standard). So there is almost ZERO moisture and no chemical contaminants in tubing. It will helps you get right result when collects soil vapor samples. Suniu ...

Dry cleaner investigation
A BEACON Passive Soil-Gas (PSG) Survey was performed at a dry cleaner site in the southeastern United States to determine if Tetrachloroethene (PCE) contamination identified beneath the dry cleaner in a prior BEACON PSG Survey was migrating off site and, if so, in which direction it was moving. This survey involved 30 field samples collected in a grid pattern. Analytical results were provided to ...

U.S. EPA Updates Vapor Intrusion Guidance
Untitled Document The attention of EPA and state environmental agencies to assessing the vapor intrusion pathway at potentially contaminated sites is growing. On March 5, 2005, EPA discussed its pending update of its draft Vapor Intrusion Guidance (Nov 2002) at the Association for Environmental Health and Sciences (AEHS) meeting held in San Diego. Also, a vapor intrusion ...

Properties and Behavior of Fuels
Fuel contaminants are generally nonhalogenated. Information presented for nonhalogenated VOCs and nonhalogenated SVOCs may also be appropriate for many of the fuel contaminants presented in this subsection. Contamination by fuel contaminants in the unsaturated zone exists in four phases: vapor in the pore spaces; sorbed to subsurface solids; dissolved in water; or as NAPL. The nature and extent ...

Vapor intrusion and indoor air quality due diligence during property transactions
Vapor intrusion (i.e. the migration of volatile chemicals from contaminated soil and/or ground water through the subsurface into overlying building structures) as a contributing indoor air has become a growing concern for property owners and prospective purchasers in recent years as it can cause significant indoor air quality problems. This is largely due to the increased focus on this issue by ...

Long-Term Volcano Surveillance via Volcanic Sediment Analysis
Why is Volcano Surveillance Necessary? Volcanoes pose a danger to life in many parts of the world. Eruptions occur relatively frequently, presenting risks to both health and infrastructure. The analysis of gas, liquid, and soil samples offers vital information regarding the levels of rare gas isotopes such as argon, neon and helium. Volcano monitoring requires the use of a number of methods to ...

Brownfields redevelopment; Understanding your environmental responsibilities
Brownfields are properties that have, or may have, contamination or the stigma of contamination that hinders the reuse of land for new development. The lure to these properties is great – seemingly prime, large tracts of land being sold for relatively inexpensive prices; the vision of unrestricted development; putting residential communities on these lands and reaping a great return. To further ...
