Project Experience

Petroleum and Polycyclic Aromatic Hydrocarbons

As part of a team of experts, evaluated the applicability of CERCLA’s petroleum exclusion to a former refinery that had been remediated under CERCLA, to determine whether remediation was required or if the observed site impacts were due to other parties’ activities. Compiled and analyzed all chemical data collected from the site and analyzed background samples and performed detailed evaluation of forensic samples. Most of the site impacts addressed under CERCLA were either petroleum excluded—that is, related to petroleum or petroleum products associated with historical railroad operations—or were below cleanup levels.

Provided technical support for allocation of liability and costs of contamination by PAHs, PCBs and metals in an urban waterway with a complex and long industrial history and multiple parties involved. Using extensive historical records, developed a model to allocate response costs. Additionally, provided chemical fingerprinting support.

Provided litigation support during trial preparation and during the trial for a case involving a natural resource damage assessment (NRDA) of two former petroleum refineries. As part of the effort, provided quick-turnaround responses to questions and requests from the attorneys.

Managed a complex project on forensic investigation to support cost allocation for a Superfund site consisting of former lumber yard with wood treatment operations and a former manufactured gas plant (MGP) adjacent to a lake. Conducted and coordinated analyses for a multiple-lines-of-evidence approach, including the use of multiple apportionment models (e.g., chemical mass balance [CMB] model, least squares mixing model) in addition to other forensic tools, such as PCA, to provide reasonable contribution estimates for PAHs in the lake sediments, which were used as part of the proposed cost allocation. Additionally, provided support for trial and depositions, including preparing for depositions, responding to motions, and developing trial demonstratives.

Conducted chemical fingerprinting analyses and historical research to identify PAH sources to a redevelopment site with observed NAPL and PAH impacts, which was located proximal to a former MGP that had operated only for a brief period in the early 1900s. Used PCA and information obtained from Sanborn maps and historical newspaper articles to determine that PAH sources distinct from the MGP had impacted the site, including two former wood pipe manufacturers. 

Evaluated the presence of impacts and timing of releases for a large, operating refinery in an insurance litigation case. During a short period of time, reviewed available documents prepared for various investigations, and evaluated the ground water data to determine the timing of the impacts. Assisted with report preparation and conducted a site visit. 

For a major oil company, provided research support for a project to evaluate the feasibility of using earthworms and composting to remediate petroleum-contaminated soils. Collaborated with university research teams, who conducted laboratory and pilot-scale composting tests. Provided input to overall research goals and objectives, in addition to specific experiments.

Managed a multi-phase investigation to evaluate impacts of coal tar pitch handling in sediments adjacent to an urban port facility. Evaluated data from forensic chemical analyses for PAHs and TPH, and a petrographic analysis using multiple forensic tools, such as principal component analysis (PCA), double-ratio plots and qualitative analysis of chemical fingerprints. Coordinated analyses involving atmospheric dispersion modeling and infiltration modeling to evaluate impacts of past handling practices to air and groundwater. 

Designed and managed a sediment sample collection and chemical analysis effort to support a forensic evaluation of sources of polycyclic aromatic hydrocarbons (PAHs) in sediments adjacent to a bulk terminal in an urban harbor, which was a Superfund site. Analyzed the data using multiple environmental forensic tools, including qualitative, quantitative, and statistical methods, and presented results of the analysis to the client. 

Screened and evaluated remedial alternatives for a residential condominium complex, which was impacted by vapor intrusion from residual petroleum contamination at the site. Performed a conceptual design of a soil vapor extraction system, groundwater pump-and-treat system, and in situ bioremediation system in support of cost evaluation for remediating the residual contamination.

Investigated the impact of a petroleum transfer facility’s operations on adjacent river sediments by application of a variety of environmental forensic techniques. This project involved sediment sampling, coordination with the analytical laboratory, and data analysis of PAH, biomarker, and TPH data. 

Chlorinated Solvents 

Managed and performed a comprehensive review of historical literature, spanning the mid-1940s to the late 1970s, on the status of knowledge regarding groundwater contamination by tetrachloroethene (PCE). Specifically, the focus was to understand what was known of dry cleaning facilities, and particularly separator water discharges from dry cleaning facilities, as potential sources of PCE to groundwater. More than 400 journal articles, government reports, and industry publications were reviewed and summarized as part of this effort. 

Managed and conducted an environmental forensic study of potential sources of trichloroethene (TCE) detected beneath a former refinery property, where documents indicated that chlorinated solvents had never been used. The investigation included an evaluation of chemical trends for TCE, daughter products, and other co-occurring chlorinated solvents (i.e. 1,1,1-trichloroethane); an analysis of historical groundwater flow patterns and chlorinated solvent plumes, and evaluation of degradation patterns. The results were presented to a regulatory agency as part of negotiation on cost allocation. 

Evaluated trends of TCE and its degradation products for groundwater in an aquifer beneath an industrial multi-party site with a large TCE plume to determine whether natural attenuation was occurring. As part of the study, estimated attenuation rates and times to reach cleanup goals for monitoring wells along the axis and cross gradient of the plume. The results indicated that natural attenuation was occurring throughout the TCE plume via biodegradation and other mechanisms, and that cleanup goals would be met with monitored natural attenuation alone sooner than anticipated.

Provided technical support for a client on remediation of PCE and TCE) in groundwater beneath a building in which the client is a tenant. Evaluated work plans on the remediation of chlorinated solvents and advised client on the design of treatability studies and pilot tests for subsurface injections. 

Conducted evaluation of results for two-phase pilot study on enhanced in situ biological (EISB) treatment of TCE. During the first phase, provided input for work plans, evaluated results and communicated finding to a client. In the second phase, worked collaboratively with consultant performing remediation and formulated a decision driven plan for conducting the second phase of the pilot. 

Evaluated PCE discharges from a drycleaner. Reviewed historical records, remedial reports, and sewer inspection videos. As part of the evaluation, assessed the condition of the sewer to determine whether PCE discharges could have originated from sewers associated with the dry cleaning facility.

Polychlorinated Biphenyls 

Advised on the appropriate analytical strategy for determining the source and the degree of weathering of PCBs in caulk material. 

In a litigation setting, provided expertise on detection and measurement of PCBs with mass spectrometric methods. The specific questions answered related to historical PCB mass spectrometric techniques, and effect of certain ionization techniques to sensitivity of detection. 

Evaluated potential historical sources of PCBs to sediments in a marine bay impacted with various historical industrial sources. Identified several potential sources not considered previously, including shipbuilding and –breaking activities. 

Assisted with PCB fingerprinting using PCB congener and homolog data in principal component analysis to identify potential sources of PCBs into a large, industrialized urban Bay. In addition to the analyses, assisted in report preparation.

Evaluated PCB issues associated with a paper sludge landfill near a Midwestern lake. Evaluated the potential pathways and landfill management practices that could have impacted the release of PCBs into the lake. Assisted in preparation of expert and rebuttal reports.

Evaluated the fate of a PCB-containing transformer oil spill into a river. Applied environmental forensic techniques to evaluate the persistence of the mineral oil in the river and the fate of the PCBs in the vicinity and downstream of the spill.

Provided expertise on the use of PCBs in non-liquid applications for a project that investigated the use of PCBs in Navy operations during World Wars I and II. Used multiple industrial archeology tools including review of patents, contemporaneous literature and agency files.

Pesticides (DDT)

Conducted an investigation of potential sources of dichloro-diphenyl-trichloroethane (DDT) in urban river sediments. Evaluated historical information regarding several facilities where DDT was previously manufactured, formulated or handled for pesticide application purposes. In addition to the historical information, utilizing DDT degradation patterns and information on by-products that were generated by other activities at the facilities, concluded that past DDT manufacturing and formulation activities were the major contributors to the sediments. 

Product Stewardship

Managed a project for calculating volatile organic carbon (VOC) emissions from a variety of coating and sealant materials using formulation records.
