Investigation, Remediation, and Monitoring of Environmental Contamination
Souder, Miller & Associates (SMA) provides environmental investigation, remediation, and monitoring services for soil, groundwater, surface water, soil vapor, and related media from the Mountain West to the Pacific Coast. Our team supports public- and private-sector clients with practical, defensible environmental solutions that help meet regulatory requirements, manage risk, and advance project goals.
From initial site assessment through remediation design, implementation, monitoring, and regulatory closure, SMA works closely with clients, regulators, laboratories, drilling contractors, and other project stakeholders to identify contamination concerns and develop cost-effective strategies tailored to site conditions and intended land use.
Environmental Investigation and Site Characterization
SMA provides environmental investigation services to evaluate the nature and extent of contamination in soil, groundwater, surface water, sediment, soil vapor, and indoor air. Our work commonly supports due diligence, property redevelopment, industrial facility management, spill response, corrective action, and regulatory compliance.
Our investigation services may include:
- Soil, groundwater, surface water, sediment, and vapor sampling
- Monitoring well installation and development
- Soil boring and test pit logging
- Groundwater elevation monitoring and flow evaluation
- Soil vapor and sub-slab vapor assessment
- Contaminant plume delineation
- Hydrogeologic evaluation
- Preparation of site characterization reports
- Corrective action plans
- Closure documentation
SMA has experience with common environmental contaminants including petroleum hydrocarbons, volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), chlorinated solvents, nitrate, metals, pesticides, and other regulated constituents.
We also assist clients with emerging contaminants, including per- and polyfluoroalkyl substances (PFAS), where evolving regulatory standards and sampling protocols require careful planning, quality control, and documentation.
Sampling, Testing, and Data Evaluation
Reliable environmental decisions begin with reliable data. SMA develops sampling plans and quality assurance procedures appropriate for the site, regulatory framework, and project objectives. Our teams coordinate field screening, laboratory analysis, chain-of-custody procedures, data validation, and interpretation to help clients understand both immediate risks and long-term implications.
Sampling techniques may include:
- Direct-push soil sampling
- Hollow-stem auger drilling
- Sonic drilling
- Rock coring
- Monitoring well installation
- Low-flow groundwater sampling
- Grab and composite soil sampling
- Surface water and sediment sampling
- Soil gas surveys
- Sub-slab vapor sampling
- Indoor air sampling
- Sampling of liquid waste or process streams
SMA also supports investigation programs involving solid, liquid, and vapor matrices where multiple exposure pathways must be evaluated together.
Remediation Planning and Implementation Support
SMA assists clients with the selection, design, implementation, and monitoring of remedial strategies that are appropriate for site conditions, regulatory requirements, budget, and future site use. Our approach emphasizes practical solutions that address environmental risk while recognizing construction, permitting, access, operations, and redevelopment constraints.
Remediation support may include:
- Excavation and disposal planning
- In-situ and ex-situ treatment evaluation
- Groundwater remediation system planning
- Vapor mitigation coordination
- Monitored natural attenuation evaluation
- Institutional and engineering control planning
- Soil management plans
- Waste characterization
- Construction- and operational-phase environmental services
For redevelopment, utility, transportation, municipal, commercial, and industrial projects, SMA can integrate environmental remediation with broader civil engineering, surveying, geotechnical, water resources, and site development services. This integrated approach helps clients reduce conflicts between environmental obligations and project delivery requirements.
Monitoring, Compliance, Permitting, and Reporting
SMA supports short- and long-term environmental monitoring programs designed to evaluate site stability, remedial performance, regulatory compliance, and closure progress. Our teams assist with permitting, agency coordination, compliance monitoring, discharge and waste management requirements, and preparation of technical reports for state and local regulatory agencies.
Services may include:
- Groundwater monitoring reports
- Vapor monitoring documentation
- Remediation system performance evaluations
- Spill response reporting
- Corrective action status reports
- Closure requests
- Permit applications
- Sampling and analysis plans
- Health and safety planning support
- Construction-related environmental compliance documentation
Expanded Drilling and Geotechnical Resources Through IME
SMA’s relationship with Inberg-Miller Engineers (IME), another Azurite-owned company, provides access to substantial drilling and geotechnical resources that can support environmental investigation and remediation projects.
IME’s capabilities include:
- Core drilling
- Hollow-stem auger drilling
- Subsurface characterization
- Monitoring well installation
- Geologic logging
- Geotechnical evaluation
- Coordinated environmental and geotechnical field services
This relationship allows SMA to better support complex subsurface investigations, particularly where environmental conditions, geologic variability, foundation considerations, groundwater behavior, or future site development plans need to be evaluated together.
Integrated Technical Services for Complex Sites
Contaminated sites often involve more than environmental sampling and reporting. SMA’s multidisciplinary services can support overall project goals by connecting environmental work with:
- Civil site design
- Water and wastewater infrastructure
- Stormwater management
- Surveying
- GIS
- UAV mapping
- Subsurface utility engineering
- Geotechnical coordination
- Construction-phase services
This broader technical capacity is especially useful for property redevelopment, brownfield reuse, industrial facility improvements, utility corridors, transportation projects, municipal infrastructure, and sites where environmental conditions may influence grading, drainage, foundations, utility placement, permitting, or construction sequencing.
From the Rockies to the Pacific
SMA provides soil and groundwater contamination investigation, remediation, and monitoring services across the Mountain West to the Pacific Coast. Our regional experience, regulatory familiarity, and integrated technical capabilities allow us to support clients from initial environmental concern through practical resolution, regulatory acceptance, and successful project completion.
Whether addressing a known release, evaluating a property transaction, managing long-term monitoring obligations, or preparing a site for future development, SMA delivers responsive, technically sound environmental services focused on compliance, risk management, and project success.
