SMA serves industrial manufacturers, insurance companies, real estate developers, state and local agencies, and energy companies. We have decades of experience in the investigation and remediation of petroleum hydrocarbons, chlorinated solvents, PCBs, and heavy metals in soil and groundwater. We are always striving to reduce costs and improve effectiveness through the use of the most practical remediation technology available for the environmental liabilities that our clients face.
SMA has successfully investigated and remediated hundreds of sites across the United States. We are experts at understanding sub-surface contaminant migration processes and source zone delineation. We have remediated sites with impacts from petroleum hydrocarbons, chlorinated solvents, heavy metals, and PCBs. We bring this experience to bear for each of our clients, no matter the scale of their project. Feel free to explore our past projects, as well as some that we are currently working on.
At SMA, we leverage our decades worth of environmental investigation and remediation experience to deliver economically and environmentally sound solutions for our clients. We combine our environmental investigation and remediation experience with cutting edge data management and visualization processes to ensure that we accurately define source areas, delineate subsurface impacts, and propose the most cost effective remediation technologies for our clients to reduce or eliminate the environmental risks that they may be facing.
The people at SMA work hard to achieve site closures, identify new investigative and remedial technologies for the environmental field, and identify precedent setting environmental law cases that are applicable for our clients.

Dissolved Oxygen in Groundwater at a Gas Station
A time lapse animation showing the results of an air sparge groundwater remediation system, installed by SMA at a gas service station in late 2017. The system increased the dissolved oxygen in groundwater, which stimulated bacterial growth, and rapidly consumed the contamination in groundwater.

3D Model of Perchloroethene (PCE) Contamination in Soil
The results of a subsurface soil investigation performed by SMA at a former printing ink manufacturer in 2014. The model identified the source area of the PCE contamination and helped to define the extent of the resulting excavation.

Chlorinated Solvents in Groundwater at a Dry Cleaner
A time lapse animation showing the results of a biological injection project performed by SMA at a dry cleaner in 2016. Emulsified edible oil was injected into the groundwater using 31 wells in order to reductively dechlorinate contamination from multiple different chlorinated solvents.

3D Model of Trichloroethene (TCE) Contamination in Soil
The results of a subsurface soil investigation performed by SMA at a former car parts manufacturer in 2015. The model identified the two source areas of the contamination and helped to design the electrical resistance heating remediation (ERH) system.

Electrical Resistance Heating (ERH) Remediation
A time lapse animation showing the results of an electrical resistance heating remediation system, installed by SMA in 2013-14. ERH remediation operates by heating the soil using electrical resistivity and extracting the contamination in the vapor phase using co-located extraction wells.
