Paul Martorano, PE

Technical Director

Mr. Martorano is a registered Professional Engineer with over twenty years in environmental assessment, remedial design, construction management, and treatment system operation, maintenance and monitoring. He holds a BS and MEng in Biological and Environmental Engineering from Cornell University. He is currently a Technical Director for Roux. Mr. Martorano’s areas of expertise include ex situ engineered treatment systems for groundwater and soil vapor; treatment technologies for emerging contaminants (1,4-dioxane, PFAS, VOCs, and metals); construction management for heavy site civil, environmental, treatment systems, and buildings; financial estimating and reserve forecasting; design management; program management; and waste characterization and disposal.

representative projects
  • Design and construction management services on behalf of an aerospace client for a 3.6 MGD groundwater pump and treatment system targeting chlorinated solvents, iron, and 1,4-dioxane. Design and construction included redevelopment of a vacant one-acre paved former recharge basin; erection of a 3,500-square-foot brick and metal pre-fabricated building with associated MEP components; process mechanical treatment system for 1,4-dioxane (hydrogen peroxide/ozone AOP), chlorinated solvents (AOP with LPGAC), and pH adjustment with sodium hydroxide, iron/solids removal (sand filtration, inclined plate clarifier, volute press);  influent large diameter dual-walled HDPE piping with leak detection; and below-grade vaults for wellhead equipment. All work was managed with a digital 3D BIM model, 4D Synchro schedule, and a digital cloud-based construction project management platform.
  • Project construction management and environmental/landfill quality assurance services on behalf of NYC Parks for the Phase I development of the North Park section of Fresh Kills Landfill in Staten Island, New York. This work included environmental compliance sampling; import of fill materials in compliance with New York State Department of Environmental Conservation (NYSDEC) Part 360 and Part 364 regulations; administration of the Storm Water Pollution Prevention Plan (SWPPP) and completion of the owner-required site inspections; State Pollutant Discharge Elimination System (SPDES) discharge monitoring, sampling, and preparation of Discharge Monitoring Reports (DMRs); review and processing of contractor submittals, payment applications, requests for information (RFIs), change orders, schedule, and other project deliverables; and coordination and execution of construction progress meetings. A Site Management Plan (SMP) and Construction Certification Report (CCR) as the “Engineer of Record” were submitted and approved by the NYSDEC in 2023.
  • Design manager and lead engineer for a PFAS water treatment system in support of a water purveyor’s expansion of an existing water supply system. Fully managed and coordinated the design process from the initial 30 percent design, though the 100 percent complete Issued for Construction package. Managed a multi-disciplined engineering team to design the system in a 3D BIM model environment. Design work was completed on an expedited schedule, given pending commercial construction that would increase the overall water demand in the area and to meet client budget requirements. Procurement work for the building, equipment, and subcontractors was completed in support of the construction and included preparation of respective requests for proposal (RFPs), review and response to bidder questions, and ultimate review and summary of the bids received.
  • Project engineer and task manager in support of remedial construction cost estimates for a client’s existing and future environmental liabilities for several different site areas. Estimates ranged in value from $0.5M to greater than $50M, and included the coordination and management of multiple sub-disciplines (civil, environmental, mechanical, electrical, structural), review of various remedial technologies (soil washing, in situ solidification and stabilization, in situ thermal desorption, electrical resistive heating, deep excavation, and disposal), and preparation of multiple conceptual site plans.
  • Project engineer and task manager in support of various sized engineered treatment systems for groundwater and soil vapor. Lead and managed digital initiatives for the various systems, including implementation of a tablet-based data collection system, automated Supervisory Control and Data Acquisition (SCADA) data collection to a cloud-based database, automated reporting and management of data outputs via direct export and daily reporting, and creation of 3D digital models of older systems using an imaging laser scanner with point cloud output. Responsible for designs and upgrades to systems, as needed, throughout the lifecycle, and providing detailed analysis and recommendations for changes based on system performance outputs. Prepared reports for regulatory approval, including site management plans; periodic review reports; operations, maintenance, and monitoring manuals; and annual engineering certification reports.
