Bioremediating Explosives Contaminated Soil

From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

Database analysis of US state regulatory guidance for organic surface soil contamination

This manuscript describes a database of US state regulatory guidance values assembled to examine the guidance applied to the most commonly regulated surface soil contaminants. Guidance values were identified for 994 different contaminants, but there is considerable variability in the number of contaminants regulated by each state and in the values applied to contaminants. Guidance values for the ...

Impact–based cost–benefit analysis model for management of crude oil contaminated agricultural soil

Evaluating the compensation payable to farmers whose farms/farmlands have been rendered unproductive due to oil spill requires adequate scientific research and improved decision–making. This work proposes a bacterial–based mathematical framework as a decision–support system for evaluating crude oil spill impact on agricultural soil. The rate of 'in situ' biodegradation of the crude oil predicts ...

Detection of petroleum-contaminated soils using Equilibrium Headspace and Methanol Extraction

Petroleum spills and leaking underground storage tanks comprise a significant portion of remediation projects. Soil removal and disposal determined based on the contaminants and concentrations present. Specific target analytes are associated with this type of contamination. A number of these compounds are classified as volatile organics and are used to assess the severity of the contamination, ...

Validation of a New Method for Screening Soil and Water for TCE Contamination

INTRODUCTION ASTM Method D 7203-06, Standard Test Method for Screening Trichloroethylene (TCE)-Contaminated Media Using a Heated Diode Sensor, (ASTM 2006) can be used to screen a sample of soil or water known to contain the halogenated volatile organic compound (HVOC) TCE. The method calls for measuring the TCE concentration in the headspace above the sample using a heated diode sensor ...

Gasoline, jet and diesel fuel soils contaminated - Petroleum product storage terminal

LOCATION: Tiverton, Rhode IslandPROJECT DATE: April, 1993 to PresentCLIENT: Confidential BACKGROUND: Soils at this 106 acre former petroleum product storage terminal have been impacted with gasoline, jet fuel, and diesel fuel over the course of 50 years. Estimates of the impacted soils range from 200,000 to 400,000 cubic yards. ACTION TAKEN: Ex-situ bioremediation is being used ...

Content Analysis of Toxic Elements in Soil by Simultaneous ICP

Contaminated soil not only leads to contamination of untreated drinking water through permeation into river water and rainwater, it adversely affects health when the soil itself is directly ingested as a child puts the ground into a stoma into a play etc. Therefore, assessment of soil toxicity using a defined method is required. I In Japan, the Soil ...

Soil Flushing

Introduction In situ soil flushing is the extraction of contaminants from the soil with water or other suitable aqueous solutions. Soil flushing is accomplished by passing the extraction fluid through in-place soils using an injection or infiltration process. Extraction fluids must be recovered from the underlying aquifer and, when possible, they are recycled. Cosolvent Enhancement Cosolvent ...

Contamination at ANA Shipyard

ANA Shipyard is located on Elizabeth river and during additional construction work, it was discovered that the ground water was contaminated with free product due to soil contaminated with a mixture of oils and greases. Excavation of soil and replacement with clean dirt was not an option since it would contaminate the river. It was recommended by the Virginia DEQ that the cleanup should be done ...

Metabolomic analysis of soil communities can be used for pollution assessment

Here we show that metabolic profiling can be used to assess the changes in biochemical profiles of soil communities living in contaminated sites. We propose the term ‘community metabolomics’ for the application of metabolomics techniques to the study of the entire community of a soil sample. We anticipate our study to be a starting point for the use of this technique to assess how communities ...

Rapid Analysis of Petroleum Hydrocarbons (TPH) in Soil and Water by Infrared Spectroscopy

In 1988 the US EPA estimated that there were 3 to 5 million underground chemical storage tanks (UST’s) in the United States, of which up to 1% would develop leaks every year. In response to growing concerns about the quality and future availability of safe drinking water, federal and state programs have begun to systematically replace virtually all UST’s installed before 1986 either with above ...

An investigation of the impact of left‐censored soil contamination data on the uncertainty of descriptive statistical parameters

Left‐censored concentration data are frequently encountered because measuring instruments cannot detect concentrations below instruments detection limit (DL). For statistical analysis of left‐censored data, environmental literature mainly refers to the following methods: maximum likelihood estimation (MLE), regression on order statistics using lognormal and gamma assumption (rROS and GROS, ...

Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach

A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with a mechanical high-speed mixer. ...

Bleeding sap and leaves of silver birch (Betula pendula) as bioindicators of metal contaminated soils

Bleeding sap of Betula pendula contained high levels of manganese on soils near ore outcrops and on acid soils, whereas high zinc levels were restricted to metal-mining and metal-smelting areas. The relationships between metal contents of bleeding sap and those of the soils were dependent on the kind of chemical soil extraction. Copper and zinc sap levels had a significantly positive correlation ...

A soil quality index for reclaimed mine soils

The quality of soils found in mines is low if they do not receive any reclamation treatment. To our knowledge, there are no still equations to evaluate the quality of metal contaminated mine soils after the application of the reclamation treatments mainly in use today (planting vegetation and amending with wastes). Therefore, the purposes of the present study was (i) to propose a method for ...

Mercury Analysis

Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
