Assessing natural contents of hazardous metals in soils by different analytical methods and its impact on environmental legislative measures
A variety of analytical techniques are commonly used to assess natural metal concentrations in soils. Although the choice of the analytical procedure may appear to be an unimportant issue, through an example from the Po Plain we document that for specific hazardous metals the arbitrary choice between separate analytical techniques may have contrasting legislative implications. Comparative ...

Asbestos in soil methods
I wanted to start off this brief technical summary with an item that appeared in the January 2009 Indoor Environment Connections publication… “Asbestos in Soil; The State of the Issue, Tom Laubenthal, Sean Fitzgerald, Alan Seagrave, P.G. In this session, Laubenthal and Seagrave will describe the nature of asbestos contamination in soil. This issue has perplexed the industry for years. What ...

The Analysis of BTEX and MTBE Using Specially Modified Purge Traps
The existence of underground storage tanks containing gasoline and other petroleum products has facilitated the need for routine testing to determine if there has been any leakage into surrounding soil and ground water. The analytical methods test for “BTEX”, which is an acronym for benzene, toluene, ethyl benzene, and xylene. In many instances, testing is not limited to these ...

Analytical method for estimating soil hydraulic parameters from horizontal absorption
Soil hydraulic properties are required to quantitatively simulate water and chemical transport processes in the vadose zone and groundwater with various numerical models. Most methods for determination of soil hydraulic properties are time consuming and expensive, which limits the application of the methods. The objective of this study was to develop an analytical method based on an assumption of ...

Data Requirements for Ground Water, Surface Water, and Leachate
It is common for ground water to be contaminated with the water soluble substances found in overlying soils. Many of the required data elements are similar, e.g., pH, TOC, BOD, COD, oil and grease, contaminant identification and quantification, and soil and aquifer characterization. Additional water quality monitoring data elements include hardness, ammonia, total dissolved solids, and metals ...

Flow Analysis – Meteorological Technology International Magazine Published Article
Many complex political, social, environmental and scientific challenges impact water resources. Snow telemetry (SNOTEL), one of the world’s largest meteorological networks, working under the US Department of Agriculture (USDA), provides critical stream flow predictions for the understanding of hydrology in western USA. For more than 100 years, predicting stream flow has been important for ...

Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory
ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
