Technologies for PFAS remediation in soil are in their infancy stage, with excavation and disposal in landfills the only currently viable option at many sites in the U.S. PFAS remediation is challenging since some compounds are resistant to destruction or degradation. The overal...

A Java-based web service is being developed within the US EPA’s Chemistry Dashboard to provide real time estimates of toxicity values and physical properties. WebTEST can generate toxicity predictions directly from a simple URL which includes the endpoint, QSAR method, and SMILES...

AWMA 2016 Measurements conference extended abstract providing a summary of preliminary analysis of the Village Green Project station data in Hong Kong.

The code base for creating versions of the USEEIO model and USEEIO-like models is called the USEEIO Modeling Framework. The framework is built in a combination of R and Python languages.This demonstration provides a brief overview and introduction into the framework.

The attached products make up the training package Dr. John McKernan will provide regarding Remediation/Rehabilitation of contaminated sites at the 2018 CEECHE Workshop on Environmental Health. Two posters and 2 presentations are attached. The workshop will provide training on t...

Before the U.S. Environmental Protection Agency issued the 1988 Guidelines for Estimating Exposures, it published proposed guidelines in the Federal Register for public review and comment. he guidelines are intended to give risk analysis a basic framework and the tools they need ...

Solid wastes produced in today’s society originate from a myriad of sources, including households, government, businesses, and industry. Current U.S. federal regulations for solid waste management have been developed to promote sound management of these wastes in a manner protect...

Tillamook Bay, a National Estuary Program site, is located on the northwest coast of Oregon. The Bay is one of Oregon’s leading producers of shellfish for human consumption. However, high levels of fecal indicator bacteria that exceed state water quality standards often r...

Results presented in this document are of particular importance when trying to understand concerns associated with the disposal of BHD in MSW landfills. The MSW decomposition process is exothermic, creating landfill temperatures that are typically greater than 37° C with the pos...

The report presents an evaluation of six materials management technologies that were assessed with respect to each technology's process, material and energy pathways, commercialization status, and associated economics. The inclusion and implementation of a materials recycling pr...

A marginal abatement cost curve (MACC) traces out the relationship between the quantity of pollution abated and the marginal cost of abating each additional unit. In the context of air quality management, MACCs typically are developed by sorting end-of-pipe controls by their rela...

In CEECHE meeting, we will present scientific, engineering information and case studies on sustainable and innovative remediation technologies used in contaminated sites in Europe and the United States. One of the most important tasks to be performed to remediate contaminated si...

A Java-based web service is being developed within the US EPA’s Chemistry Dashboard to provide real time estimates of toxicity values and physical properties. WebTEST can generate toxicity predictions directly from a simple URL which includes the endpoint, QSAR method, and ...

In general, a flow in life cycle inventory data refers to an input or output to a process. Flows may be of two broad types: elementary flows or intermediate (known as “technosphere”) flows according to ISO 14044 (ISO 14044 2006). Elementary flows may be defined as mat...

Epoxies are widely used in various applications, including coatings, electronics insulations, and waterproofing applications due to their excellent properties such as good adhesion, electrical insulation, and heat resistance along with the strong mechanical property. Currently, n...

Bioavailability research of soil metals has advanced considerably from default values to validated in vitro bioaccessibility (IVBA) assays for site-specific risk assessment. Previously, USEPA determined that the soil-size fraction representative of dermal adherence and consequent...

There are limited systematic comprehensive studies on the aging of different composites, release of nanoparticles, and identifying their different forms. The polymer type, the aging conditions including UV dose and moisture affect the amount of the release of nanofillers (nanopar...

The current study evaluates the effectiveness of the combined application of Peracetic acid and ultraviolet radiation as alternative disinfectant agents to the traditional chlorination of wastewater effluents. Various pathogens (E. coli, enterococci and fecal coliforms) were eval...

State governments are showing an increasing interest in the concept and application of sustainable materials management (SMM). SMM implies that a life cycle perspective be taken on materials management and environmental and social impacts of materials be taken into account in eva...

Livestock waste may cause air quality degradation from ammonia and methane emissions, soil quality detriment from the in-excess nutrients and acidification, and water pollution issues from nutrient and pathogens runoff to the water bodies, leading to eutrophication, algal blooms,...

Use of biotrickling filter (BTF) for gas phase treatment of volatile trihalomethanes (THMs) stripped from water treatment plants could be an attractive treatment option. The aim of this study is to use laboratory-scale anaerobic BTF to treat gaseous chloroform (recalcitrant to bi...
