Representative Recent Projects and Publications
Onondaga Lake Superfund Site, NY: Mr. Mauro is a consulting expert to an industrial client on the sources and contribution of PAHs, petroleum products, and other chemicals to the Onondaga Lake superfund site. The work has included directing sampling and analysis, forensic data interpretation, and development of a cost allocation formula that utilized the multi-chemical nature of the contamination (PAHs, PCBs, PCDDs/PCDFs, metals, industrial chemicals), risk assessment, and contribution of background sources.
Gowanus Canal Superfund Site, NY: Mr. Mauro was the PCB consulting expert to the Allocator for the multi-party cost allocation at the Gowanus Canal superfund site. Mr. Mauro also provided assessment of the sources and amounts of PAHs and metals in the Canal.
Passaic River Superfund Site, NJ: Mr. Mauro is a consulting expert to a confidential client on the sources and contribution of PCBs, PCDDs/PCDFs, PAHs, and metals to the Passaic River superfund site. Tasks included evaluation of historical emissions/capacity data, performed fate and transport analyses, and critically reviewed and revised the proposed allocation formulas proposed by an independent allocator.
Berry’s Creek Study Area Superfund Site, NJ: Mr. Mauro is a consulting expert to a confidential client on the sources and contribution of PCBs, metals, and other chemicals to the Berrys Creek Study Area and Ventron/Velsicol superfund site in New Jersey. Tasks have included review of PCB usage for numerous historical industrial processes and operations and their potential handling of PCBs, interpretation and mapping of potential PCB sources to sediment, and critique of an allocation formula proposed by others.
Chlorinated Solvents at a Former Textile Mill, MA: Mr. Mauro prepared a report on the nature and source of chlorinated solvents at a commercial property that used to be a textile mill. Concentrations, daughter to parent chemical ratios, stable carbon and chlorine isotopes, and groundwater modeling were used to show that a release of PCE occurred upgradient of the property and has migrated within a fairly narrow water bearing zone beneath and beyond the client’s property.
PAH Sources and Potential Ecorisk in Sediment of a Small River, MA: Mr. Mauro used forensic PAH and TPH data, pore water analysis (ASTM D 7363), and equilibrium partitioning calculations to show that impacts from a former manufactured gas plant (MGP) site were limited in extent and that elevated concentrations of PAHs could remain in the bulk sediment before pore water PAH concentrations posed a risk to benthic organisms.
PCDDs/PCDFs at a Chemical Manufacturing Plant, RI: Mr. Mauro used principal components-based multivariate models to show that most of the PCDD/PCDF at a small former chemical manufacturing and barrel reconditioning site originated with a single source. The variability in the PCDD/PCDF composition remote from the identified source was caused by the influence of mixing with the ubiquitous PCDD/PCDF background in the older industrial area.
