Hepatic EROD induction in the common kingfisher from an e‐waste recycling site
The health effects of exposure to electronic waste (e‐waste) derived pollutants are an important issue. We explored the association between the hepatic levels of e‐waste derived halogenated contaminants, including polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs), and hepatic ethoxyresorufin‐O‐deethylase (EROD) activity of the common ...

Geotechnical Geophysics: ReMi survey at a hazardous waste landfill.
PROJECT: ReMi surveys at a closed waste disposal site LOCATION: The Dalles, Oregon PROJECT DESCRIPTION: Designed and performed ReMi Surveys at a closed 8-acre waste disposal site to passively measure microtremors within the upper 55 feet of the subsurface, in order to determine the depth to competent (non-rippable) basalt ...

Improving the Cost-Effectiveness of Hazardous Waste Site Characterization and Monitoring
Executive Summary U.S. EPA’s Office of Solid Waste and Emergency Response is promoting more effective strategies for characterizing and monitoring hazardous waste sites. In particular, the wide-spread adoption of a new paradigm which uses an integrated triad of systematic planning, dynamic work plans, and on-site analysis for data collection and technical decision-making at hazardous waste sites ...

A simple method to check for natural attenuation downstream of abandoned waste disposal sites
Evaluations of waste sites are based on the assessment of whether conditions for Natural Attenuation (NA) processes are favourable. A method is proposed as a first check for effects of NA in the groundwater emissions. For the application of the method, concentrations of the concerned substance and of a tracer must be available at observation wells at different distances from the source, ...

Hazardous waste sites and property values: a French case study in the light of US analyses
This paper aims to evaluate the impact of a polluted site on property values by using the hedonic price method. The case study concerns a lead foundry in a previously industrialised area in northern France. The results are fairly convincing. The impact is confirmed, but appears to be especially apparent at relatively close distances. More than one mile away, the impact is much weaker. Moreover, a ...

An expert system on site selection of sanitary landfill
It is desirable to encapsulate heuristic and empirical knowledge including hydrological and bio-geochemical considerations into the selection process of a potential landfill site. This paper delineates a prototype expert system, which has been developed using a commercially available microcomputer-based expert system shell VISUAL RULE STUDIO, for the selection of a landfill site. VISUAL RULE ...

Air‐plant exchange of brominated flame retardants at a rural site: Influencing factor, interspecies difference, and forest scavenging
Brominated flame retardants (BFRs) in eucalyptus leaves and pine needles from a rural site in southern China were measured to investigate the air‐plant exchange. The mean concentrations of BFRs were higher in pine needles (79.8 ng/g dry weight) than in eucalyptus leaves (74.5 ng/g), whereas an inverse result were found for the leaf surface particles (LSPs), with mean concentrations of 3490 and ...

A procedure for detecting childhood cancer clusters near hazardous waste sites in Florida
Despite over 20 years of research on childhood cancer clusters and hazardous waste sites, little evidence has been produced to indicate a causal relationship. Nevertheless, the perception of a childhood cancer cluster being located near a hazardous waste site can raise fear and uncertainty, and it demands attention from health officials. To investigate this public health concern, the author used ...

Integrated Geophysics: EMI and ReMi surveys at a hazardous waste landfill
PROJECT: EMI and ReMi surveys at a closed hazardous waste disposal site LOCATION: The Dalles, Oregon PROJECT DESCRIPTION: Designed and performed a 5-ft spaced EMI survey in tandem with ReMi surveys at a closed 8-acre waste disposal site. The goals of this integrated geophysical investigation were to 1) detect landfill boundaries, 2) identify locations of buried metallic debris / drums and 3) to ...

Hazardous waste disposal in Germany: a case study of the site in Billigheim, Baden-Wurttemberg
The disposal of hazardous waste is a very critical issue. It is associated with many risks. Efforts are made to minimise these by consistent legislation and by proper treatment of the waste. The goal of a hazardous waste disposal site, as described in this paper, is to ensure that hazardous waste is treated and disposed of in a way that does not harm human beings or the environment. To assure ...

A New Apparatus for the Evaluation of Electro-Kinetic Processes in Hazardous Waste Management
Possible uses of electro-kinetics for hazardous waste site remediation are being investigated. This paper describes a new apparatus which has been specifically designed, fabricated, and assembled to evaluate the viability, feasibility, practicality, and potential costs of these conceivable techniques experimentally. Results of studies on the existence of electro-osmotic flow in compacted clay and ...

Cleanup of Hazardous Waste Site Samples by Solid Phase Extraction
ENVI-Florisil solid phase extraction tubes meet the requirements for pesticide recovery from water, sediment, and soil samples taken from hazardous waste sites, as described in US EPA Contract Laboratory Program methodology. Mean recovery of nine pesticides was 82% or better, well within the specifications of the CLP method. A procedure for recovering the pesticides is described. ...

Application of current risk-based remediation criteria for the post-closure assessment of a former National Priorities List (NPL) site
Hurricane accelerated erosion and land loss of the Mississippi River coastal zone has necessitated a re evaluation of environmental risk at closed National Priority List (NPL) industrial waste sites in Louisiana, USA. Clean up criteria of a site were evaluated under the Louisiana Risk Evaluation Corrective Action Program (RECAP 2003). An assessment of the closed site using RECAP 2003 indicated ...

The impact of an open waste disposal site on soil and groundwater pollution
A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 101000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 1001000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the ...

South West water maintains a reliable fleet with iNet - Case Study
Challenge Personal gas monitors are required to protect employees from hazardous gases while conducting work across a number of South West Water’s drinking water and waste sites. The company’s gas detector fleet was nearing end of life and the team feared that their instruments were no longer reliable. The team found it difficult to keep up with the maintenance tasks required of ...

Building and breaking a bridge of trust in a Superfund site remediation
Trust is widely recognised as a key variable in perceptions and decision-making about environmental risks. However, most considerations of trust treat it as a simple two-agent relationship. Based on an analysis of a contaminated site cleanup in New Jersey, we identify a more complex construction of trust formed between multiple stakeholders. We refer to this construction as 'bridging'. In the ...

In Situ Remediation Technology Status Report: Electrokinetics
The purpose of this document is to describe recent field demonstrations, commercial applications, and research on electrokinetics for either treatment of soil and ground water in situ or to increase the solubility and mobility of contaminants to improve their removal by pump-and-treat remediation. It is hoped that this information will allow more regular consideration of new, less costly, and ...

Jefferson county waste transfer, Bessemer, Alabama - Case Study
CONSTRUCTING JEFFERSON COUNTY ALA.'S new solid-waste transfer site to fit an existing county lot challenged the project’s contractor and engineers to develop a unique solution for a potentially severe erosion-control problem. The county-owned site offered good access for large vehicles and seclusion from residential areas, which made obtaining the proper zoning and permits less complicated. ...
