PROJECT MERIT: Innovation in Crisis

GEI Consultants, Inc. for empowering emergency response planning by creating the Tulare Lake Atlas. In early 2023, severe storms and atmospheric rivers resulted in unprecedented rainfall and snow in Central California, with the Tulare Basin 6-Station precipitation index recording the wettest period on record. As substantial snowpack in the southern Sierras began to melt, it led to the reemergence of the previously dry Tulare lakebed, posing a significant threat to vital agricultural lands, critical infrastructure, and populated areas. Emergency management officials faced a daunting task due to the absence of a comprehensive hydrologic and hydraulic model for this historically dry lakebed. Addressing this critical gap, GEI collaborated with the California Department of Water Resources to pioneer the creation of a groundbreaking Atlas that offered an innovative visualization of the potential inundation areas corresponding to varying water volumes and associated water surface elevations. The Atlas significantly aided emergency response personnel, equipping them with invaluable technical insights to foresee and strategize against potential threats. Its swift development and effectiveness in empowering emergency planning marked it as a groundbreaking tool during an unprecedented crisis.


PROJECT MERIT: E-Waste Remediation

TRC for leading the e-waste investigation, remediation/cleanup, and collaborative management of the regulatory process for the former Tatooine Industries facility in Burns, Wyo.  In 2022, TRC completed removal of 1.2 million lbs of e-waste and 83,000 lbs of leaded glass, while recycling approximately 75%. In June 2023, after samples verified that contaminants of concern were below cleanup levels, the Wyoming Department of Environmental Quality issued the Certificate of Completion. The Tatooine facility had operated as an e-waste recycling facility from 2010 to 2014 but was abandoned after its owner’s arrest. The blighted property quickly posed risks to the community, including safety concerns, fire damage, illicit operations, and illegal dumping. Many Wyoming municipalities, state government entities, and schools had paid to have their e-waste recycled at the facility, and its unexpected closure resulted in their e-waste being permanently abandoned. TRC helped to bring this important facility back into community use. A lease agreement is pending that is expected to will result in positive business operations and economic benefits through increased jobs and tax revenues.


PROJECT MERIT: Sediment Remediation

EA Engineering, Science, and Technology, Inc., PBC for leading design and construction oversight to remediate impacted sediment across more than 200 acres in-water and on the shoreline of the St. Louis River, while also enhancing wetland habitat and creating new open water. Located within the St. Louis River Area of Concern in Duluth, Minn., the Spirit Lake Great Lakes Legacy Act Sediment Remediation Project involves a multi-disciplinary team that includes consultants, contractors, and the U.S. Environmental Protection Agency’s Great Lakes National Program Office and their nonfederal sponsor. The Spirit Lake site presented many challenges for design, construction, and permitting. These included a large geographic area, competing stakeholder interests, consideration of sensitive resources and environmental work windows, balance of on-land and in water construction operations, large-scale restoration planning, community involvement, significant cultural resources coordination, and adaptive management. The project represents a decade of work conducted in a holistic manner from feasibility studies through to developing a design to balance remedial goals, habitat restoration, and stakeholder needs.

PROJECT MERIT: PFAS Treatment Facility

Tetra Tech, Inc. for working with the City of Dayton, Ohio to address per- and polyfluoroalkyl substances (PFAS) contamination in the City’s water supply, from planning to implementation. Once constructed, the PFAS treatment facility will be the largest in the United States. Tetra Tech developed a $400 million master plan for the City to address asset management needs at the City’s two 96 MGD water treatment plants (WTPs) and well fields. The strategy includes expanding pumping and recharge at the Miami WTP, installing a 48-inch interconnect between the WTPs, and installing a 96 MGD of PFAS treatment at the Ottawa WTP. To implement PFAS treatment, Tetra Tech will perform a Rapid Small Scale Column Test to select an adsorptive media (granular activated carbon, ion exchange, and novel adsorbents) for treatment, site the treatment process within a congested site, and develop a 30% design package for implementation through alternative delivery. Tetra Tech designed four new wells, sited eight future wells, and is currently designing 25 MGD of recharge expansion within the Miami well field. In total, Tetra Tech is planning and designing more than $200 million in improvements to address emerging contaminants and maintain a high-quality water source for the region.


PROJECT MERIT: Sites Reservoir Project

ICF for serving as the environmental compliance and permitting consultant for the Sites Reservoir Project, leading all permitting and agency coordination, and developing a mitigation strategy that satisfies both permitting and environmental compliance commitments. Final EIR/EIS was completed in November 2023. The Sites Reservoir Project is a planned 1.5 million-acre-foot off-stream reservoir that will capture and store excess stormwater from the Sacramento River for use in dry years. Sites Reservoir would be the first new reservoir in California in decades. ICF worked closely with the Sites Project Authority to ensure the necessary documents and assessments were prepared to streamline both the environmental compliance and permitting processes, be legally defensible, and gain agency support and approvals. ICF also engaged the permitting agencies early in the process to set clear expectations and milestone requirements. ICF’s strategy proved invaluable in preparing early environmental documents to help secure project funding; working with project engineers to ensure environmental tasks were integrated with the project planning, engineering design, and construction; coordinating with federal and state agencies to secure various permits and approvals; and developing a mitigation strategy.


PROJECT MERIT: Model for Bird Aircraft Strike Hazard

Marstel-Day LLC for developing the first ever bird aircraft strike hazard (BASH) model for predicting risks and incidental takes to federally listed birds and bats as part of a nationwide Programmatic Biological Assessment (PBA) covering flight operations at 32 Air Force bases. The integrated model utilizes Poisson probability modeling, surrogate species modeling, adjustments for observant bias in BASH reporting by aircraft type, analysis of more than 300,000 BASH incidences, risks to 35 federally listed birds and bat species across the nation, and analysis of millions of flight operations for all aircraft types at 32 bases. Formal consultation occurred with all USFWS regional offices and headquarters to develop a nationwide incidental take permit to cover all Air Force airfield operations, culminating in a Biological Opinion (BO) drafted by USFWS in 2023. This approach enables the Air Force to significantly streamline NEPA and Endangered Species Act (ESA) compliance through establishment of a national bank for incidental takes to be applied to all military aircraft strikes from 32 bases. It also affords greater flexibility to the Air Force when changes in military mission require changes in airfield operations or new aircraft, as this approach eliminates the need to prepare additional BA/BOs in the future.


PROJECT MERIT: Sterling Natural Resource Center

Rincon Consultants, Inc. for working with East Valley Water District (EVWD) for several years to secure Waste Discharge Requirements (WDRs) for the Sterling Natural Resource Center (SNRC), a brand-new wastewater treatment/water reclamation plant in San Bernardino County, Calif. The WDRs—the water quality permit that incorporates State Water Resources Control Board’s groundwater replenishment and reuse project regulations—were issued by the Santa Ana Regional Water Quality Control Board on December 1, 2023. The SNRC is a groundwater replenishment and reuse project (GRRP) that will spread recycled water for recharge of the Bunker Hill groundwater basin. Constructed between 2018 and 2023, this potable reuse project will ensure reliable water supplies are available to the disadvantaged communities served by EVWD. By increasing the amount of local groundwater in storage, this project will ensure a local, drought-proof water supply for a California community that has faced repeated multi-year droughts and supply constraints. Based on extensive community engagement, SNRC also provides unique public meeting space and parkland available to the surrounding community. SNRC will begin operation in early January 2024, delivering highly treated recycled water to nearby recharge basins and securing a safe and reliable water future for the community.



The Minnesota Pollution Control Agency (MPCA) for conducting an assessment and finalizing a Feasibility Study for Project 1007, a flood control initiative finalized in 1987. This study aims to comprehend the project’s role in propagation of PFAS contamination within the East Metro Area of the Twin Cities. Project 1007 directs water from the Tri-Lakes area to the St. Croix River via stormwater pipes, open channels, and creeks. One such creek flows through a former PFAS disposal site, where PFAS leached into the groundwater for decades. Designed and implemented by AECOM, the assessment involved sampling soil, sediment, surface water and groundwater in several communities. The result is an integrated surface water, groundwater, and fate and transport model that identifies site-specific PFAS trends. The project is informing targeted regional remedial action options while leading the way for PFAS remediation in the United States. In December 2022, MPCA became the first state government to pilot a combination of innovative technologies to address PFAS. Surface activated foam fractionation takes contaminated water and turns PFAS into a foam that separates from the water. The foam concentrate is then coupled with destruction technologies, including AECOM’s DE-FLUORO unit where electrochemical oxidation breaks the carbon-fluorine bonds.


PROJECT MERIT: Food recovery and waste prevention

The San Gabriel Valley Council of Governments (SGVCOG) retained the services of SCS Engineers to help member cities comply with state mandates regarding edible food recovery and food waste prevention. Implementing commercial food recovery programs is important to ensure members meet state compliance, avoid penalty fees, and reap environmental and humanitarian benefits, such as addressing food insecurity. SCS collaborated with the SGVCOG team and local stakeholders to analyze commercial edible food generation, calculate edible food recovery capacity in the region, develop safe food recovery/donation strategies, and implement education and outreach to establish one of the largest SB 1383 edible food recovery programs in California. The combined effort has helped SGVCOG better understand how and where food waste is generated and to identify the capacity of food recovery organizations to recover excess edible food from businesses. The program has conducted inspections at over 500 businesses and recovery organizations to educate them on food waste reduction and edible food recovery. 


PROJECT MERIT: Emergency Response and Solutions

Burns & McDonnell for emergency response to an oil release from the Keystone Pipeline System in rural Washington County, Kansas in December 2022 and for follow-up design and implementation in 2023. The release, identified as the Milepost 14 Incident, discharged 12,397 barrels of crude oil, impacting roughly 3.48 miles of creek and posed a risk of downstream migration into a river and reservoir. Burns & McDonnell’s emergency response team was on site within hours of the release, working with client TC Energy to mitigate risk to nearby wildlife habitats, agriculture and the community. In 2023, Burns & McDonnell collaborated with its client and local agencies and led a group of subcontractors to design and implement a solution that included: 

  • 24/7 incident response, including removing and protecting wildlife and cataloging plant species.
  • Capture/analysis of drone footage and 3D site models.
  • Diverting 3.7 million cubic meters of surface water over land to investigate and remediate impacted creek bed and banks. 
  • Designing, installing and operating the seventh largest water treatment plant in Kansas (designed and built in 70 days) with a 71,200-cubic-meter water treatment pond.
  • Treating 204,000-plus cubic meters of impacted water with zero regulatory exceedances. 
  • Evaluating and remediating impacted soil and groundwater.
  • Restoring stream banks and habitats and reintroducing wildlife.

The Milepost 14 project was completed within a year, equating to 3.4 million total project hours performed without significant incident or injury, with around 135,000 hours attributable to Burns & McDonnell, which continues to work with TC Energy on long-term monitoring.


PROJECT MERIT: Site Remediation

TerraTherm, Inc., a Cascade Company, teamed with Jacobs to thermally remediate the Velsicol Chemical Superfund Site located along the Pine River in St. Louis, Mo. Historical chemical manufacturing operations produced chemicals and metals including DDT and 1,2-dipromo-3-chloropropane (DBCP). Between 2017 and 2023, in situ thermal conduction heating (TCH) was used in three phases to reduce dense non-aqueous phase liquids (DNAPL) mass and mobility and eliminate offsite migration of DNAPL to surface water and sediments in 18 discrete source areas at the site. Unexpected removal mechanisms were encountered during TCH operations. While designed to remove the bulk of mass via vaporization and treatment via thermal oxidation, during the first TCH phase, DNAPL recovery was the dominant removal mechanism. During this phase, > 90% of the total mass was recovered as DNAPL, followed by 98% and 97% of the total mass removal in the following phases, respectively. The majority of the DNAPL mass was recovered late in the remedy when most of the site had been at boiling temperatures for a substantial amount of time. Over 380,000 lbs of contaminants were removed from the 18 source areas—more than seven times the original estimate—and more than 90% were removed as DNAPL.


PROJECT MERIT: Site Remediation

Cascade Environmental for playing a pivotal role in the successful remediation of a former chemical manufacturing site in Keasbey, N.J. Cascade worked closely with the client and site engineer to address groundwater contamination, specifically tert-butanol (TBA), impacting adjacent properties. Cascade’s innovative approach involved in situ solidification and stabilization (ISS) of approximately 15,000 cubic yards of TBA-impacted materials. Complications in prior site characterization led to the real-time discovery of stone fill in the area of former remediation. This posed unforeseen challenges in safety, remedial efforts, and material management. Cascade addressed these stone-related complications successfully, adapting mix designs during installation of a slurry wall and managing workspace and excavation support during ISS. Amidst the stone management, the team identified unknown utility lines and relocated numerous conduits. Cascade’s strategic approach mitigated risks and enhanced overall project success. Cascade demonstrated adaptability within unexpected conditions all while working within the originally proposed budgets and schedules. 



Pinyon Environmental Inc. for the Central 70 Project in Denver and located near industrial and commercial uses and two U.S. Environmental Protection Agency superfund sites. Pinyon utilized the Public Private Partnership approach for the reconstruction of the corridor, adding toll lanes, removing the viaduct, lowering portions of the interstate, and placing a cover park over a portion of the lowered interstate. In preparation for construction and to minimize potential delays and additional costs, Pinyon developed a proactive sampling and agency approach. Pinyon collected 170 soil samples to identify areas where soils were available for material reuse, completed over 100 Phase I Environmental Site Assessments, and sampled 30 wells. The project team coordinated with the Colorado Department of Public Health and Environment in the development of a Beneficial Reuse Materials Management Plan (BRMMP), which further defined the allowable limits for material reuse onsite, and the requirements and process for environmental covenants. Pinyon audited the contractor’s work to document compliance with technical requirements and the BRMMP, reviewed management plans, conducted field audits, and coordinated with regulatory agencies. Due to the unique BRMMP and subsequent reuse of materials on site, the project team reduced costs, as excavated materials were estimated to total over 1.3 million cubic yards.


PROJECT MERIT: Riverfront Park

AECOM/BASF for making major strides in 2023 in transforming a former industrial property into an ecological showcase. Progress on the Riverfront Park project in East Newark, N.J. included completion of design, installation of climate resiliency features, and commencement of Park construction. Located in an “environmental justice” community, Riverfront Park explores human connectivity with ecological systems with a design focused on biodiversity, featuring pollinator gardens, meadows, wooded areas, and native plantings. This universally accessible park includes a 1,000-foot-long riverfront boardwalk to allow users to explore the shoreline and enjoy sweeping views of the Passaic River. An urban amphitheater provides a peaceful setting for community members to connect safely with the natural world. The nature-based design addresses 15 of the 17 UN Sustainable Development Goals and features sustainable building materials and practices. Rain gardens highlight use of green infrastructure to manage stormwater. Collaboration between government, businesses, NGOs, and the community has enabled fast track restoration of this impaired property. The Park will be fully constructed in 2024, turning back the clock and transforming the East Newark waterfront into an extraordinary community asset, a rich landscape providing human and ecological uplift after more than 150 years of industrial use.



TECHNOLOGY MERIT: Sustainable PFAS Remediation

ecoSPEARS for developing sustainable technologies to eliminate “forever chemicals” from contaminated sediments, soils, and water. Existing methods for remediating contaminants in waterways primarily rely on the disruptive practice of dredging, which disturbs aquatic ecosystems, results in the additional release of harmful substances, and has significant economic consequences. ecoSPEARS’ innovative onsite remediation technologies are both green and sustainable. The NASA-developed SPEARS technology is a non-invasive surgical approach to sediment and porewater remediation. The technology is comprised of a specialized mat that contains an array of polymer “SPEARS” filled with proprietary solvent to absorb toxins. The mats are pressed down into the contaminated sediment, where they passively absorb contaminants. ecoSPEARS’ solutions have won international acclaim, notably through collaboration with the International Pollutants Elimination Network (IPEN). The technology has been integrated into international environmental policies, such as IPEN’s non-combustion technology for Persistent Organic Pollutants (POPs) Waste Destruction.


Ivey International Inc. (Vancouver, BC) for developing a new formulation from its Ivey-sol® enhanced remediation technology to address PFAS contamination in groundwater, soil, and bedrock regimes. Tests of the PFAS-SOL® formulation conducted in the United Kingdom by IVEY in collaboration with the University of Greenwich, with analysis by ALS, have shown significant PFAS mass removal rates. The PFAS-SOL® formulation is non-toxic, biodegradable, and pH neutral. It is based on non-ionic formulations, with a novel additive, that can selectively desorb contaminants and render sorbed, globular and nonaqueous phase liquids (NAPL) soluble in the aqueous phase – that is, it forms a non-emulsified mixture with water and can thus be more easily controlled and removed from impacted soil, fractured bedrock, groundwater, and surface water while maintaining plume control. “With PFOA/PFOS, given the liability,” says George ‘Bud’ Ivey, president of Ivey International Inc., “if you lose control of your plume at parts per trillion it presents a great deal of risk when using absorptive technologies.”

TECHNOLOGY MERIT: PFAS Site Evaluation Toolset

Jacobs for developing a proprietary (patent pending) PFAS evaluation toolset to map hundreds of PFAS transformation pathways under environmentally relevant conditions and to identify differing PFAS sources and release history. Jacobs’ PFAS pathway mapping is paired with hundreds of chemical “fingerprints” of source products. These evaluation tools, backed by the latest peer-reviewed publications and machine learning, create a unique “3D visual fingerprint” that presents data according to how the compounds transform and attenuate in nature. Jacobs’ approach simplifies interpretation and communication, including understanding of precursor transformation, a key to effective decision making for investigation, risk assessments and remediation. The toolset is used globally to identify source areas, model PFAS precursor transformation and refine fate and transport and attenuation pathways. This toolset accelerates understanding of the conceptual site models and streamlines investigation strategies. For example, Jacobs worked on an Australian national program of PFAS investigations across 37 civilian airports. Five years of data at one site were quickly processed using the Toolset, and a previously unknown source area was identified. In turn, Jacobs refined the conceptual site model and adjusted the sampling plan to close this data gap.


TECHNOLOGY MERIT: Ambient Air Monitoring

Burns & McDonnell for developing and implementing the Ambient Air Monitoring System, a sensor-based alert system and dashboard, for a client with an aggressive schedule for a $300-million EPC project driven by IRA tax incentives for renewables manufacturing and environmental justice considerations in the community. A state regulatory agency required ongoing air monitoring during expedited construction. The client needed an interface that was user-friendly and easily accessible for the construction team and would not interrupt construction work. The system is comprised of a network of air quality sensors around the perimeter of the construction site that aggregates data into a digital dashboard. Burns & McDonnell advised the client on recommended action levels for initiating dust control measures and programmed those levels into the dashboard. The technology solution included:  

  • Monitoring and display of ambient particulate matter (PM) concentrations onsite with location-based labels.
  • Automatic email deployment to the construction team if action levels were exceeded.
  • An ArcGIS Survey123 questionnaire to document responses to elevated PM concentrations.  
  • Logic to assist with implementation of a fugitive dust control plan.

The system verifies compliance and allows construction work to continue uninterrupted. Burns & McDonnell anticipates that more clients will require monitoring, data documentation and delivery in the future as sustainability and environmental justice efforts drive transparency and regulatory change.



Citadel EHS for partnering with an AI consultant to develop a solution for Phase 1 ESAs using ChatGPT.  Phase 1 ESAs are an important starting point in the life cycle of real estate redevelopment. However, for many EHS consulting firms, they generate little profit, entail high risk (you can’t afford to miss anything), incorporate large amounts of data review and reporting, have tight deadlines, and are often done in large part by less experienced staff. Given the copious amounts of data to be uploaded, which would cost a vendor thousands of dollars, Citadel’s partner wrote project-specific code in Python and worked with the data provider to structure the data in a way that it could be efficiently uploaded. The end result was that Citadel was able to provide extra eyes with AI to assist the Phase I preparer review, sort, and comment on data of significance and automate sections of the final report. What is also noteworthy is that Citadel chose not to make the AI solution proprietary and has reached out to other industry firms that may benefit from the technology.

Other traditional analytical techniques for measuring the presence of herbicides are time-consuming, labor-intensive, and have limitations on what can be detected.


TECHNOLOGY MERIT: DebrisFlow Predictor

Dr. Richard Guthrie, a landslide expert at Stantec and the Director of Geohazards, together with Andrew Befus, one of Stantec’s application developers, for designing and building DebrisFlow Predictor software to predict the impacts of a debris flow by path, depth, total area and volume. Debris flows are extremely rapid flow-type landslides that travel long distances from their source and impact communities, lives, infrastructure, and the environment. Most often triggered by rainfall, debris flows are a serious hazard in mountain environments. That hazard increases many times after a wildfire season. Without adequate modeling, the run-out and potential impact of debris flows are hard to define. DebrisFlow Predictor is a visually intuitive, computationally efficient program that requires limited data inputs and quantifies the landslide threat in the receiving area—that zone where we build, work, live, and play. Stantec is converting the model into a Software as a Service (SaaS) that clients can use as a cloud-based tool. DebrisFlow Predictor is for anyone exposed to debris flow hazards who wants a visually intuitive way of answering Will I be OK?, “Will my infrastructure be impacted?” “How bad will it be?” DebrisFlow Predictor provides a new robust solution, to an old and dangerous problem.
