    Industrial Sector Experience

    Faucet and Fixture Manufacturing Client (Elyria, OH)
    Project Manager/Lead Engineer

    Jonathan worked to progress this site, with more than 100-years of manufacturing history, from initial Environmental Site Assessment (ESA) to No Further Action (NFA) under the auspices of the Ohio EPA – Voluntary Action Program.

    Based on the results of Phase I and Phase II ESA investigations, several identified areas were determined within site boundaries. Jonathan managed site investigation activities to confirm and delineate existing soil and groundwater impacts and prepared the corresponding Phase I and Phase II ESA Reports.

    Identified areas with impacted soil and groundwater were targeted for remediation. As part of this, Jonathan prepared a Remedial Feasibility Evaluation and recommended focused soil removal with Enhanced Bioremediation as a polishing step. Jonathan conducted waste classifications and determinations, prepared technical specifications to support large-scale soil removal, and managed the soil removal activities. He also designed and oversaw three (3) separate applications of Enhanced Bioremediation in fractured sandstone underlying and downgradient of the removed soil. Post remediation, Jonathan evaluated soil and groundwater data to evaluate remedial performance and to gauge microbial reductive dechlorination potential. Establishment of reducing conditions, order of magnitude decreases in chlorinated ethene concentrations, and continued reductive dechlorination potential have been observed and support no further remedial action at the site.

    Following remediation, Jonathan managed vapor intrusion evaluations inside an active building at the site, which yielded unacceptable risk in indoor air. Thus, Jonathan utilized a soil gas survey to identify areas of elevated chlorinated solvent impacts in sub-slab, and subsequently managed diagnostic testing, sub-slab depressurization system (SSDS) design, SSDS installation, and successful operation of the SSDS.

    A NFA letter, which is supported by an Ohio EPA-approved urban setting designation (USD), was submitted for the site in early 2014. Based upon frequent communication with Ohio EPA up front, minimal comments are expected and NFA (with institutional and engineering controls) is anticipated to be achieved.

    Connector and Interconnect System Manufacturing Client (Columbia, SC)
    Project Manager/Lead Engineer

    Upon request by the South Carolina Department of Health and Environmental Control (SCDHEC), Jonathan worked with the Client to evaluate the feasibility of additional source remediation to meet applicable standards in groundwater. To accomplish this, Jonathan prepared a Feasibility Study Work Plan that incorporated high-resolution, site characterization techniques to identify any sequestered chlorinated solvent impacts in underlying heterogeneous alluvial materials. Jonathan managed the successful implementation of the Work Plan. Following implementation, the results of Waterloo Profiling and high-resolution soil characterization/sampling confirmed that low levels of trichloroethylene (TCE) were sequestered in underlying clays, and that low-permeability gradational materials were supporting transport of elevated TCE concentrations to downgradient receptors. A Feasibility Study Report was prepared, which evaluated the efficacy of various remediation alternatives to target these low-permeability units.

    In addition, Jonathan managed periodic groundwater monitoring and remediation system operation at this site under the auspices of a SCDHEC consent order and an active NPDES permit. As part of system O&M, he managed the construction permit application process, design and installation, and permit approval for a telemetry system, which was approved and installed, and effectively decreases inspection frequencies, associated exposure hours, and O&M costs.

    Holding Company Client (Crozet, VA)
    Project Manager/Lead Engineer

    Jonathan worked to guide this Client through the state-led RCRA Corrective Action process and implement successful interim remedial applications within a fractured crystalline rock aquifer. The purpose of interim remedial measures was to address exceedances of industrial screening levels in soil and to facilitate groundwater concentrations that would allow environmental indicators (EIs) to be “under control”.

    Initially, Jonathan prepared the Phase I RCRA Facility Investigation (RFI) Work Plan, managed the soil and groundwater characterization activities, and prepared the Phase I RFI Report. Subsequently, he prepared the Phase II RFI Work Plan, managed the implementation thereof, and prepared the Phase II RFI Report. RFI work identified chlorinated ethene and petroleum impacts in underlying saprolite and deep fractured bedrock at the site, which resulted in groundwater exceedances and unacceptable trends at the property line.

    Jonathan prepared an Interim Measures Work Plan. Upon Virginia Department of Environmental Quality approval, he managed Interim Measures at the site, which included the design and construction of a large-scale, source-area treatment system combining soil vapor extraction (SVE) in saprolite and an Enhanced Bioremediation recirculation system in underlying fractured rock. Innovative fractured-rock hydrologic tests (i.e., pulse interference tests and tracer tests) and biogeochemical evaluations were conducted and evaluated to support the remedial design. Jonathan also designed and managed in situ chemical oxidation (ISCO) to remediate petroleum and chlorinated solvent impacts in saprolite at a second identified source area via shallow injection of hydrogen peroxide and ozone, and deep injection of permanganate.

    Performance monitoring results from Interim Measures indicated successful SVE removal of PCE and TCE in the unsaturated overburden, progress of the anaerobic reductive dechlorination process in deep fractured rock, and significant decreases in petroleum and chlorinated solvent concentrations from ISCO injection. These results were used to re-evaluate EIs and move the site forward within the RCRA Corrective Action process.

    Faucet and Fixture Manufacturing Client (Sanford, NC)
    Project Manager/Lead Engineer

    Jonathan worked to guide this Client from a prescriptive North Carolina Department of Environment and Natural Resources (NCDENR) regulatory program into a risk-based program, which would facilitate a more cost-effective and timely route to closure.

    Initially, Jonathan prepared and implemented Phase I and Phase II II Remedial Investigation (RI) Work Plans to investigate chlorinated solvent, petroleum, and metal impacts. As part of RI, membrane interface probe (MIP), soil boring, and soil gas survey evaluations were utilized to identify existing source areas underlying the building. A vapor intrusion evaluation was conducted to evaluate potential risk to facility personnel and to identify areas for focused remediation. No unacceptable risk was determined in indoor air. In addition, an ecological risk assessment was conducted to demonstrate that metal impacts do not adversely affect the ecology of an on-site stream. Jonathan prepared RI Reports, which volumetrically delineated residual impacts in soil and groundwater, and that removed sediments/surface water impacts and vapor intrusion from further consideration.

    To help reduce mass flux and produce groundwater concentrations amenable to entry into NCDENR’s Risk Based Program, Jonathan prepared a Remedial Action Plan (RAP) to address a residual source of chlorinated ethane and 1,4-dioxane underlying the active manufacturing Facility. Jonathan managed RAP implementation, which included injection of activated persulfate within the impacted vadose and saturated zones. Performance monitoring and groundwater modeling are being utilized to evaluate the effects of activated persulfate injection, and the results thereof are in the process of being leveraged to demonstrate eligibility for moving the site into the Risk Based Program.

    Security Product Manufacturing Client (Milwaukee, WI)
    Project Manager/Lead Engineer

    In the interest of directing this site to closure under the auspices of Wisconsin Department of Natural Resources (WDNR), Jonathan worked with the Client to assemble historical characterization and remediation documentation, identify and evaluate data gaps, and evaluate potential remedial action options to produce acceptable data trends.

    Following historical soil and groundwater remediation efforts, groundwater data trends did not facilitate closure. To better understand these trends, Jonathan identified data gaps and implemented remedial design investigation activities to evaluate them. Further evaluation confirmed that residual chlorinated solvent and 1,4-dioxane impacts were sequestered within the tight glacial till, underlying and surrounding where previously remediated, and continued to leach into groundwater at concentrations above enforcement standards. Based on an updated Conceptual Site Model, Jonathan worked to identify and evaluate remedial action options (RAOs) to address these residual impacts. Scopes and estimates of probable costs were prepared for each RAO, and each RAO was evaluated against specific WDNR criteria. RAO selection is currently in progress with the Client.

    Furthermore, Jonathan conducted vapor intrusion evaluations within the active wastewater treatment building on the property and along the down-gradient property lines. Risk assessment was conducted and used to confirm the lack of risk in indoor air within the building. However, off-site vapor intrusion evaluation is required and is in process in accordance with WDNR guidance.

    Building Product Manufacturer (Rocky Mount, VA)

    Jonathan provided engineering support to a Client who desired to determine the magnitude of their existing liability at a site that they no longer owned and was undergoing USEPA RCRA Corrective Action. Jonathan prepared the preliminary remedial design and developed estimated probable costs for an interception trench for recovery of free-phase mineral oil with dioxins, furans, and pentachlorophenol. In addition, Jonathan scoped and prepared estimated probable costs for removal of approximately 1,500 feet of impacted sediment from a receiving stream, proper sediment waste management and disposal, and stream restoration activities. Where applicable, Jonathan worked with qualified Subcontractors to generate reliable costs. The estimated probable cost was provided to the Client and was used for internal discussion between the Client and the property owner, and to better direct the progression of the project.

    Chemical Sector Experience

    Specialty Chemical Client (Covington, VA)
    Project Manager/Lead Engineer

    Following successful Corrective Action; Jonathan is working with the Client, the Virginia DEQ, and City Officials to transfer this project from a rigid regulatory program into a voluntary program, which will allow the site to be redeveloped as a local, outdoor recreational park.

    Initially, Jonathan successfully managed the implementation of a Virginia DEQ-approved Corrective Action Plan (CAP) at the site. Prior to implementation, Jonathan worked to update the CAP to promote successful Enhanced Bioremediation for remediation of localized carbon tetrachloride impacts in shale. In addition, prior to implementation, Jonathan managed remedial design investigations to focus injection (of pH buffer and long-term emulsified electron donor) into impacted shale and alluvial deposits. Following CAP implementation, three (3) years of subsequent performance monitoring results have yielded decreases in carbon tetrachloride and associated reductive dechlorination products to non-detect concentrations, and establishment of reducing conditions amenable to chlororespiration. Jonathan has coordinated between the Client and multiple regulatory programs, to leverage these successful results and move this site towards a pathway for closure and reuse.

    Specialty Chemical Client (East Brunswick, NJ)

    Jonathan provided internal engineering support for source area investigation and remediation at an active industrial facility underlain by residual tetrachloroethylene (PCE) impacts. As part of this support, he provided guidance regarding soil sample constituents and geotechnical parameters to be collected, review of proposed soil boring and new monitoring wells locations, and proposed groundwater sample collection suites. He has also supported remedial feasibility evaluation, remedy selection, preparation of technical specifications and bid documents, and the bidding process. Focused soil excavation followed by Enhanced Bioremediation is in the process of being implemented to meet New Jersey Department of Environmental Protection requirements.

    Petroleum and Natural Gas Sector Experience

    Pipeline Transportation and Energy Storage Company (various locations in VA)

    The Client had several active petroleum storage terminals within the Commonwealth of Virginia that required updates to compliance documentation. As part of this, Jonathan directed and reviewed terminal inspections, determined required documentation for each terminal as permitted, managed the preparation of updated compliance documents (i.e., SPCC Plans, SWPPPs, O&M Manuals, Slug Control Plans, and permit applications), and reviewed and certified these documents. During regulatory facility visits, these compliance documents were subjected to regulatory auditing and review, and were approved without comment.

    Retail Clients (various locations)

    Jonathan has internally supported several Retail Clients with site investigation and remedial design. Jonathan has employed fingerprinting analyses to determine whether commingling from adjacent retail stations was affecting the Client’s site, as well as recommended innovative site investigational tools (e.g., laser-induced fluorescence (LIF) survey) to characterize areas of greatest petroleum impacts. In addition, Jonathan has prepared remedial designs (e.g., in situ chemical oxidation, dual-phase extraction, etc.) to remediate identified petroleum impacts.

    Real Estate Investment Trust Corporation (various locations in MD, TX, and VA)

    The Client had several oil-containing facilities, for which compliance documentation was either unknown or non-existent. Jonathan managed inspections at each facility to identify the characteristics of oil-containing tanks and equipment and to confirm the presence or absence of appropriate compliance documentation. Based on facility visits and review of existing documentation, where obtainable, Jonathan prepared a comprehensive descriptive summary of each facility, along with a concise outline of required documentation. Based on this information, the Client is in the process of bringing these oil-handling facilities into compliance with applicable Federal and State regulations.

    Federal Sector Experience

    Air Force Center of Environmental Excellence (AFCEE) (Marietta, GA)
    Engineer in Training

    Under the direction of AFCEE and under the auspices of the Georgia Environmental Protection Division; Jonathan participated in several innovative USGS investigations in a chlorinated solvent-impacted fractured rock aquifer.

    Jonathan supported the fabrication of a borehole straddle-packer system, which he utilized to investigate chlorinated ethane impacts and hydraulic properties in discrete fractures as deep as 600 feet beneath land surface. As part of this investigative work, Jonathan analyzed borehole geophysical logs to identify yielding fractures and determine straddle packer placement, collected water-quality and hydraulic data within discrete fractures, and evaluated straddle packer results. This evaluation was used to determine the volumetric characterization of contamination in deep fractured bedrock and which fracture zones actively promoted off-site migration at high concentrations and flux. These results were also used to assess the applicability of Enhanced Bioremediation in the fractured rock aquifer.

    Jonathan also provided remediation technology review to AFCEE and participated in other fractured rock aquifer investigations, which included: determination of discrete zones of chlorinated ethene discharge into an off-site creek using diffusion samplers; statistical analysis of water-quality data to determine temporal trends with respect to degradation of chlorinated ethenes and bio-geochemical processes; and investigation of the hydraulic response of a heterogeneous, anisotropic fractured rock body to a three-step, constant-rate pumping test.
