DNAPL CHARACTERIZATION METHODS AND APPROACHES: PART 2: COST COMPARISONS Mark L. Kram Arturo A. Keller Joseph Rossabi Lorne G. Everett ABSTRACT Contamination from the use of chlorinated solvents, often classified as dense nonaqueous phase liquids (DNAPLs) when in an undissolved state, pose environmental threats to ground water resources world-wide. DNAPL(More)
Contamination from the use of chlorinated solvents, often classified as dense nonaqueous phase liquids (DNAPLs) when in an undissolved state, represents an envi­ ronmental challenge with global implications. Mass-transfer limitations due to rate-limited dissolution can lead to longterm aquifer persistence for even small volumetric fractions. The(More)
A simple analytical model is presented for predicting subsurface gas flow to a vadose-zone well in response to atmospheric pressure fluctuations (barometric pumping). The effective radial permeability (kr) in the vicinity of the well is determined during model calibration using less than two weeks worth of data. By combining the flow solution with a(More)
Dense non aqueous phase liquid (DNAPL) contaminants, comprised of chlorinated aliphatic compounds, are a major source of groundwater contamination at the Savannah River Site (SRS). To successfitlly remediate a site contaminated by DNAPLs, it is imperative that the slowly dissolving, non-aqueous phase source be fbund and removed. There are few technologies(More)
Smoking related illness and deaths are a significant problem globally. In the U.K. the government has been funding a nation-wide network of specialist clinics that provide support to smokers who want to quit since 1999. The specialist clinic in Whitechapel covers the boroughs of Tower Hamlets and the City of London. We analysed the records of 516 smokers(More)
