SCS Engineers announces expanded odor consulting and laboratory capabilities to help clients continue receiving specialized odor evaluation, monitoring, analysis, and control services as Odor Science & Engineering, Inc. prepares to close. Odor Science & Engineering has recommended SCS Engineers to carry forward services many industrial and municipal clients have relied on for odor problem definition, odor sampling and analysis, ambient monitoring, staff training, and cost-effective odor control planning.
“Our clients have trusted Odor Science & Engineering for many years to provide objective, technically sound answers to challenging odor problems. It is important to me that, as OS&E winds down its operations, our clients have access to a team that understands the science of odor and shares our commitment to practical, defensible solutions. I am confident that SCS Engineers is the right organization to carry this work forward, and I am pleased to recommend SCS to our clients and colleagues.” OS&E President, Martha O’Brien.
Both firms are recognized leaders in specialized odor consulting, whose work has helped clients define odor issues, establish control requirements, design control systems, conduct odor emission sampling, complete odor panel analysis, monitor ambient odors, and train client staff in odor investigation and monitoring procedures.
SCS Engineers’ expanded services will support both existing and new facilities. For existing operations, SCS helps diagnose and solve odor issues by identifying contributing sources, determining the level of control needed, and developing practical, cost-effective control strategies. For new facilities, SCS supports the design of ventilation and odor-control systems to help prevent odor impacts once operations begin.
The transition strengthens SCS’s existing capabilities in odor management, ambient air monitoring, air quality, and environmental compliance. SCS applies field, laboratory, and modeling methods to detect, measure, and predict fugitive chemical and odor impacts. The team supports clients with odor assessments, odor dispersion modeling, complaint data analysis, smoke release studies, field and laboratory olfactometry, tracer studies, source sampling, air monitoring, and mitigation planning.
“Odor issues are highly site-specific, often technically complex, and important to communities, facility owners, and regulators,” said SCS Vice President and National Expert on Ambient Air Monitoring and Odor Impact Assessment, Paul Schafer. “By expanding our odor laboratory and consulting capabilities, SCS is positioned to provide continuity for OS&E clients while offering the national reach and multidisciplinary environmental expertise our clients need.”
SCS’s odor work serves a broad range of industrial and municipal settings, including landfills, composting facilities, wastewater treatment plants, food processing operations, manufacturing facilities, oil and gas operations, cannabis cultivation facilities, and other industrial sites where odor emissions, nuisance concerns, regulatory requirements, or public complaints require objective investigation and defensible solutions.
Current and prospective clients seeking odor consulting support can contact SCS Engineers to discuss service continuity, project transition needs, laboratory analysis, field investigations, odor control planning, or staff training.
SCS Engineers is excited to participate in A&WMA’s Odor Management Conference, taking place May 12–14, 2026, at the Radisson Blu Mall of America in Bloomington.
Building on the success of the 2024 Odor Management Conference and A&WMA’s odor webinar series, this conference will explore a broad range of odor-related topics, including odor science, chemical forensics and source identification, field assessment and sampling methods, electronic sensing, modeling, policy and regulation, controls and mitigation, community impacts, and industry best practices.
The program will feature international perspectives on odor management, along with a pre-conference webinar, technical tour, tabletop exhibition, and networking reception.
SCS Engineers Presenters Wednesday, May 13
Session 3A: Laboratory – Odor Panel/Chemical Analysis 8:00 am – 8:30 am
OM-02 Olfactometry: From Field Methods to Laboratory Setting Odor Panels, Understanding How the Application of Different Methods Generates Varying Results
Christopher Petro presents a technical session examining how different odor measurement approaches produce varying results that influence regulatory compliance, community relations, and mitigation strategies.
The presentation will compare field-based methods and ASTM-standard laboratory odor panels, outlining the strengths, limitations, and practical considerations of each. It will also explore emerging regulatory trends, performance-based permitting, and the integration of chemical surrogates with sensory data to improve source-attribution and odor-management outcomes.
Session 4A: Odor Management & Control 10:30 am – 11:00 am
OM-08 Making Scents of Cannabis Odor Control: Evaluating Mitigation Technologies and Trade-offs
Eva Luu and Armando Garcia Hurtado combine ambient air monitoring and data analysis expertise with biochemistry to address cannabis odors. Many jurisdictions defer to operators to identify and implement appropriate odor control technologies, yet few comparative evaluations exist. Over six years of field testing, our speakers show how considering environmental conditions, maintenance requirements, cost-effectiveness, and public perception gives decision makers a practical framework to match control technologies to specific operational scenarios.
We look forward to sharing insights and connecting with peers advancing the science and practice of odor management. Register now!
