“…Case history 1 is the West Virginia light NAPL (LNAPL) (gasoline) site in Sauer and Costa (2003). Two monitoring wells were sampled, MW-1 contained LNAPL and MW-2 (without LNAPL) that was located 50-ft downgradient of MW-1.…”

“…The effective solubility relationship has been shown to be valid by number of researchers (Leinonen and Mackay, 1973;Burris and MacIntyre, 1985, 1986a, 1986b, 1987Broholm and Feenstra, 1995). The effective solubility relationship has also been applied to groundwater problems (Mackay et al, 1991;Sauer and Costa, 2003;Broholm et al, 2005). It is valid for chlorinated solvents as well as hydrocarbons.…”

“…The diagnostic ratios chosen proved of value in assessing whether the hydrocarbon composition of groundwater samples may have been the result of contact with a specific NAPL. A potential limitation of the Sauer and Costa (2003) approach is that the diagnostic ratios chosen may provide a relatively narrow examination of the available data (i.e., only the compounds within the diagnostic ratios chosen are utilized) and diagnostic features within the broader dataset may be missed in the forensic analysis.…”

“…Inclusion of the groundwater data in forensic chemical fingerprinting analysis can be highly desirable and crucial because groundwater data often constitute the bulk of a case database. Sauer and Costa (2003) recently introduced an approach to forensic analysis using both NAPL and groundwater data in which the water solubility characteristics of selected compounds were used to identify sets of diagnostic ratios useful in fingerprinting. The diagnostic ratios chosen proved of value in assessing whether the hydrocarbon composition of groundwater samples may have been the result of contact with a specific NAPL.…”

An advanced chemical fingerprinting approach, called nonaqueous phase liquid (NAPL)-groundwater (GW) finger printing, is presented for relating NAPL, soil, and groundwater data. This approach is accomplished by utilizing the "effective solubility" relationship and a hypothetical n-component NAPL to convert NAPL, soil (containing residual NAPL), and groundwater data to common frames of reference with respect to both phase and dilution. The resulting NAPL-GW fingerprints make it possible to perform detailed forensic analysis incorporating all three data types (assuming minimal confounding effects of attenuation processes and non-ideal solution behavior). Three case histories using the NAPL-GW fingerprinting approach are presented, illustrating its utility in forensic analysis when appropriately applied.

“…The plot is a ratio of the sum of tracers more concentrated in one physiographic region, divided by the sum of those tracers more concentrated in the other physiographic region, and plotting against the sum of all tracers by sample sites. Plotting these tracers showed a weathering ratio (Costa et al 2005;Sauer and Costa, 2003).…”

Abstract:Fine sediment sources were characterized by chemical composition in an urban watershed, the Northeast Branch Anacostia River, which drains to the Chesapeake Bay. Concentrations of 63 elements and two radionuclides were measured in possible land-based sediment sources and suspended sediment collected from the water column at the watershed outlet during storm events. These tracer concentrations were used to determine the relative quantity of suspended sediment contributed by each source. Although this is an urbanized watershed, there was not a distinct urban signature that can be evaluated except for the contributions from road surfaces. We identified the sources of fine sediment by both physiographic province (Piedmont and Coastal Plain) and source locale (streambanks, upland and street residue) by using different sets of elemental tracers. The Piedmont contributed the majority of the fine sediment for seven of the eight measured storms. The streambanks contributed the greatest quantity of fine sediment when evaluated by source locale. Street residue contributed 13% of the total suspended sediment on average and was the source most concentrated in anthropogenically enriched elements. Combining results from the source locale and physiographic province analyses, most fine sediment in the Northeast Branch watershed is derived from streambanks that contain sediment eroded from the Piedmont physiographic province of the watershed. Sediment fingerprinting analyses are most useful when longer term evaluations of sediment erosion and storage are also available from streambankerosion measurements, sediment budget and other methods.
