Maintaining neutral pH in deep soils and ground water utilizing insoluble colloidal buffers

by Remediation and Natural Attenuation Services, Inc. (RNAS)  (Nov. 10, 2014)

ABSTRACT: Optimal pH for most biodegradation processes falls between 6.5 and 8.5. Enhanced bioremediation in poorly buffered soils and ground water is likely to lower pH below 6.5 as the added electron donor produces carbon dioxide and or ganic acids. The common agricultural practice of liming soils adds alkalinity and adjusts soil pH by mixing ...

Approximated EU GHG inventory: proxy GHG estimates for 2013

by European Environment Agency (EEA)  (Oct. 28, 2014)

Objective of the report This report provides estimates of greenhouse gas (GHG) emissions in the European Union (EU) and its Member States for the year 2013, covering the full GHG inventory (all sectors, except land use, land‑use change and forestry (LULUCF), and all gases). These estimates are also referred to as approximated ('proxy') ...

LNAPL remediation using electrical resistance heating

by TRS Group, Inc. (TRS)  (Oct. 31, 2014)

Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were ...

In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating

by TRS Group, Inc. (TRS)  (Oct. 31, 2014)

An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been ...

Mississauga Case Study (In Situ Gas Thermal Remediation (GTR™))

by GEO Inc  (Oct. 29, 2014)

In Situ Thermal Desorption in conjunction with soil vapor extraction was used to remove volatile organic compounds which contaminated the groundwater and saturated soil areas of a former metal fabricating facility in Ontario, Canada. The site had VOCs detected above the Canadian water standard in various monitoring well locations.  The ...

Surfactant enhanced in-situ remediation of DNAPL impacted soil and groundwater - Montreal refinery

by Ivey International Inc.  (Jul. 10, 2014)

Abstract A Montreal chemical refinery reduced the dichlorobenzene and other dense non-aqueous phase liquid (DNAPL) impacts on the soil and groundwater where a railway line is adjacent to an above ground storage tank farm. Ivey-sol® surfactant mixtures were injected three times during a two week pilot test, into a series of in-situ wells. The ...
