Professional engineer with 12 years of experience in wastewater treatment planning and design, including water quality evaluation, optimization of treatment plants, design of treatment processes, development of basis of design reports and analysis calculations, coordination of multidisciplinary engineering studies and designs, preparation of engineering cost estimates, coordination with equipment vendors, engineering operations manual preparation, construction management, and system commissioning.
Engineer for a comprehensive engineering feasibility study to assess the technical, economic, and operational viability of soil and groundwater remediation of a large contamination. Responsibilities included evaluating project requirements, performing site assessments, analyzing design alternatives, and identifying potential risks. Collaborated with multidisciplinary teams to develop cost estimates, timelines, and resource plans, ensuring compliance with industry regulations and sustainability standards. Delivered detailed reports and recommendations to support informed decision-making and optimize project outcomes. Alternatives included a combination of in-situ and ex-situ technologies resulting in extensive collaboration with hydrogeologists, geochemists, permitting specialists, civil, electrical, and process disciplines leads.
Led multidisciplinary feasibility study design of an industrial wastewater treatment system to evaluate effluent compliance for perfluoroalkyl and polyfluoroalkyl substances (PFAS) in a region undergoing regulatory review. Major unit processes included precipitation and separation, membrane bioreactor, granular activated carbon, and reverse osmosis for removal of organics and PFAS. Secondary processes included dewatering solids management equipment and an evaporation equipment to evaluate zero liquid discharge.
Led multidisciplinary engineering design, procurement, construction, and commissioning of a wastewater treatment system with major unit processes being a sequencing batch reactor, granular activated carbon, and ion exchange treatment processes for removal of organics and PFAS. Secondary processes included a solids management treatment train consisting of a solid thickening tank and a filter press. Regulatory requirements resulted in a condensed schedule, but the commissioning date met client expectations resulting in no unexpected costs.
Field engineering lead for the evaluation of a High-Density Sludge (HDS) treatment plant’s capability under different hydraulic and contaminant loading conditions; and assessing the necessary water polishing steps to enable effluent discharge from the site. Executed a 1% of full-scale pilot test of the HDS and water polishing (ultrafiltration, ion exchange, and reverse osmosis) that demonstrated adequacy of the approach to achieve long-term compliance with the Consent Decree requirements. The pilot evaluated eighteen different scenarios that included multiple site source waters over the course of 4 months with continuous operation.
Led process mechanical design of a groundwater treatment system with a biological fluidized bed reactor for perchlorate. Major unit processes included groundwater extraction and conveyance, biological treatment of perchlorate with a fluidized bed reactor, granular activated carbon vessels to treat 1,4-dioxane, secondary treatment of perchlorate with ion exchange, and groundwater re-injection. Groundwater extraction and injection wells were constructed to strategically extract contaminated water and reinject treated water to enhance mass removal.
Process and mechanical design lead of a 1.2 MGD groundwater, surface water, landfill leachate and contaminated runoff from site activities treatment system for hexavalent chromium, heavy metals, volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), and radionuclides. Design of the wastewater/groundwater treatment system required coordination of a multidisciplinary engineering team and stakeholder management. Major unit processes designed included flow equalization, chemical reduction/precipitation, granular activated carbon adsorption, ion exchange, pH adjustment, and residuals management. Additional tasks included technical specifications, operation and maintenance plan, basis of design calculations and hydraulic calculations.
Design team member of a pilot and full-scale groundwater pump and treat system for the removal of benzene, toluene, ethylbenzene, and xylene (BTEX), hexavalent chromium, and total dissolved ions. Major unit processes included groundwater extraction, conveyance, ion exchange treatment of chromium, granular activated carbon vessels to treat BTEX, electrodialysis reversal for ion removal, pH adjustment, and groundwater re-injection.
Onsite lead for the Ultraviolet (UV) – Advanced Oxidation Process (AOP) testing being conducted at a drinking water treatment facility in Colorado. The influent water to the facility is contaminated with 1,4-dioxane and other organic compounds which cannot be treated by conventional treatment methods. Supported the conceptual and detailed design of the pilot system, pilot testing plan development, on-site coordination with the client and the overall on-site operation and maintenance of the pilot unit.
Preliminary feasibility study design team member of a direct potable reuse treatment plant focused on drought resilience. Treatment technologies evaluated include denitrification filtration, microfiltration, reverse osmosis, UV AOP, and granular activated carbon adsorption. Evaluated historical data to determine the feasibility of achieving treated water goals. Supported the development of the pilot test plan that was submitted to the Texas Commission on Environmental Quality (TCEQ) for review and approval.
