Founded in 2003, CMA is a SAM-registered small business providing unique solutions to the challenges of identifying, quantifying, and monitoring groundwater discharge to coastal, estuarine, and aquatic systems — backed by patent-protected technology developed through two decades of research and field work. With a perfect safety record since inception, we collaborate with multi-national engineering and environmental firms to detect, characterize and sample pollutants at the groundwater-surface water interface (GSI).

What We Do

Core Services

CMA provides specialized field, analytical, and consulting services for environmental assessment and monitoring in coastal, estuarine, and other aquatic systems.

Porewater Screening and Sampling

Using the patented Trident Probe we conduct screening surveys to identify areas of porewater discharge and can sample these areas for VOCs, metals, PAHs, PCBs, PFAS, and other contaminants.

Groundwater Seepage Quantification

Our patented UltraSeep systems quantify groundwater seepage across a broad range of environments, from inland ponds and lakes to tidally influenced rivers and bays.

Proven PFAS Sampling Capabilities

Using our Trident probe, we have successfully sampled for ambient levels of porewater PFAS as well as at sites with known contamination.

Why CMA?

Capabilities You Can't Find Anywhere Else

Exclusive Nationwide Providers of UltraSeep & Trident Probe

CMA provides two industry-leading technologies for groundwater-surface water assessment. The UltraSeep meter quantifies discharge rates and contaminant fluxes with unprecedented accuracy in both tidal and non-tidal environments. Use of the Trident Probe enables us to rapidly map, characterize, and sample groundwater discharge zones through integrated temperature and conductivity measurements.

These innovative systems — developed and refined through decades of laboratory and extensive field work — are the basis for CMA's unique capabilities. Because of this clients have a legitimate basis for sole-source procurement, streamlining the contracting process while ensuring access to our advanced technologies.
