Comprehensive Environmental Solutions for Landfill Compliance, Operations & Risk Management
Modern landfill operations face evolving environmental, regulatory, and public-facing challenges. From gas generation and leachate treatment to air emissions and emergency response, today’s operators need more than just data—they need integrated expertise and rapid, science-based action.
Montrose Environmental provides environmental support for landfills across the project lifecycle, backed by multidisciplinary teams, advanced technologies, and defensible data. Whether you’re navigating compliance, optimizing operations, or building community trust, we help you meet your goals with clarity and confidence.
Full-Spectrum Services—from Sampling to Strategy
Our environmental solutions for landfill operations include:
- Field sampling and stack testing
- Laboratory analysis
- Leachate treatment evaluations
- Real-time ambient air and odor monitoring
- Permitting, emergency response, and public health assessment
Every service is underpinned by rigorous data validation, auditing, and transparent reporting—delivering the insights needed for compliance, risk mitigation, and public communication.
Key Service Areas
Our teams develop and execute comprehensive environmental monitoring programs across all landfill media:
- Landfill gas
- Leachate
- Groundwater
- Stormwater and surface water
- Soil and ambient air
We support operators with permitting, compliance tracking, and proactive strategies that align with local, state, and federal regulations. Our integrated approach ensures defensibility, transparency, and adaptability to evolving expectations.
We transform air monitoring from a regulatory necessity into an operational asset.
Our Solutions Include:
- Sensible EDP™ Platform – A sensor-agnostic environmental data platform that integrates real-time emissions data into a single, intuitive dashboard
- Automated Alerts – Real-time notifications to mitigate risks and avoid costly violations
- Mobile Monitoring – Our PTR-ToF-MS vans provide on-site odor fingerprinting, source identification, and advanced compound analysis
- Advanced Stack Testing – Including NOₓ, SO₂, VOCs, particulate matter, and HAPs for flares, engines, and oxidizers
With in-house QA/QC, faster turnaround times, and EPA-compliant methods, we ensure precision and consistency across all air testing activities.
Leachate management is more complex than ever—with PFAS, ammonia, organics, and regulatory pressure on the rise.
Our Approach:
- Site-specific treatment strategies based on local water chemistry and discharge requirements
- Pilot studies using real-world samples and conditions
- In-house R&D lab and patented water treatment technologies (through ECT2)
- PFAS, ammonia, and organic removal, with scalable, adaptive treatment designs
From treatability testing to full-scale deployment, our team helps ensure both performance and compliance.
Through our in-house lab network (including Enthalpy Analytical), we offer specialized landfill-focused testing for complex analysis or matrices with fast turnaround times and tight control over data:
- Landfill gas
- Groundwater and surface water
- Leachate and stormwater
- PFAS and other emerging contaminants
- Ambient air and emissions samples
Our lab analysts work closely with project teams to achieve the lowest reporting limits, rapid turnaround times, and customized methods tailored to each site’s needs.
When unplanned events or public complaints occur, response time and defensible data are critical. Our emergency response teams (including CTEH) provide rapid, science-based support for:
- Real-time air monitoring (mobile or perimeter systems)
- Odor and gas migration investigations
- Regulatory and litigation support
- Agency liaison and inspection response
We deliver clear, credible insights that protect your operational integrity and ease regulatory interactions.
Community concern and legal scrutiny around landfill emissions are growing. Our health science teams offer:
- Health risk assessments by board-certified toxicologists and epidemiologists
- Exposure modeling and data analysis (real-time and historical)
- Science-backed reporting for regulatory agencies, attorneys, and the public
We help you separate fact from perception—and communicate findings with clarity and confidence.
We guide landfills through the permitting and regulatory maze with minimal disruption to operations:
- Landfill siting, design, and construction oversight
- SWFP, CUP, AQMD/APCD, ARAP, and stormwater permitting
- SWPPP development and monitoring
- Groundwater treatment and monitoring
Our permitting teams are strategic, fast-moving, and highly experienced in solid waste regulatory frameworks across jurisdictions.
From legacy contamination to active site impacts, we design and execute remediation strategies tailored to your geology, hydrology, and operational footprint.
Our Strategies Include:
Groundwater Remediation
- Pump-and-treat systems
- Permeable reactive barriers (PRBs)
- Monitored natural attenuation (MNA)
Soil Remediation
- Excavation and off-site disposal
- Soil vapor extraction (SVE)
- Stabilization/solidification (S/S)
All solutions emphasize defensible data, cost-effectiveness, and alignment with long-term site closure goals.
