A simple method to determine mineralization of 14C‐labeled compounds in soil
Degradation of organic compounds in soil is often determined by measuring decrease of parent compound and analyzing occurrence of its metabolites. However, determination of carbon species as end products of parent compound dissipation requires the use of labeled materials which allow more accurate determination of the environmental fate of the compound of interest. The current conventional ...

Characterizing scale- and location-dependent correlation of water retention parameters with soil physical properties using wavelet techniques
Understanding the correlation between soil hydraulic parameters and soil physical properties is a prerequisite for the prediction of soil hydraulic properties from soil physical properties. The objective of this study was to examine the scale- and location-dependent correlation between two water retention parameters ( and n) in the van Genuchten (1980) function and soil physical properties (sand ...

Automated screening of explosives in soil samples by online SFE-SFC-MS
There are a large number of explosives-contaminated sites in the US, Europe, and Asia. High levels of explosives in soil can threaten the health of humans, livestock, and wildlife. A number of remediation efforts are underway, which require the analysis of explosives in soil samples. Recently, a new technique was introduced that allows the automated supercritical fluid extraction and SFC ...

A method for measuring saturated hydraulic conductivity in Anisotropic soils
Saturated hydraulic conductivity (Ks) is an important soil parameter that is difficult to measure, especially in an anisotropic medium. Many methods for determining Ks have been developed over time, but taking different water flow directions into consideration is possible in only a few of them; furthermore, these few methods cannot be universally applied. The method proposed here allows Ks to be ...

Vapor Intrusion Testing/Sampling in Buildings
What is Vapor Intrusion? Vapor intrusion occurs when volatile chemicals lodged in soil or groundwater rise to the surface and are released into the air. This can occur in the open air or into buildings, offices, factories, warehouses, vacant, or abandoned. Vapor intrusion testing/sampling is a method of determining if known or suspected ground contamination is a result in these chemical vapors ...

Four Soil Collection Methods that Actually Work
Without taking the time to perform a soil analysis, it’s nearly impossible to determine what your soil needs to help your crops thrive. While it’s controversial to label any single soil collection method the best, there are four most commonly used methods that work well across most fields. Based on the pros and cons of each, you can determine which tools will help you collect soil ...

Streamside management zones effectiveness for protecting water quality after forestland application of biosolids
Received for publication August 1, 2008. Biosolids, materials resulting from domestic sewage treatment, are surface applied to forest soils to increase phosphorus (P), nitrate, and ammonium availability. Retaining streamside management zones (SMZs) can limit nutrient pollution of streams. We delineated 15-m SMZs along three intermittent streams in an 18-yr-old Pinus taeda L. plantation. We ...

S2C2 Inc. utilizes EQuIS, RockWorks and ArcGIS implementing the Triad approach
When implementing the Triad Approach, S2C2 Inc. (S2C2) relies upon EarthSoft’s EQuIS,ESRI’s ArcGIS and Rockware’s RockWorks software toptimize the management andvisualization of large data sets. The USEPA’s Triad Approach incorporates the following threecomponents: systematic planning, real-time measurements and dynamic work strategies. Theprimary goal of this approach is tstreamline site ...

Removing CVOCs under a building equals increased property value tucker, Georgia
TRS Group, Inc. (TRS) worked as a subcontractor to Brown and Caldwell to remediate five chlorinated volatile organic contaminant (CVOC) source areas in the soil under a manufacturing building. To accomplish this, Electrical Resistance Heating (ERH) remediation, it was necessary to place over 70 electrodes and vapor recovery wells through the main floor of the facility and to use angled electrodes ...
