Specialized field, analytical, and consulting services focused on assessment and modeling of environmental fate and transport processes in coastal, estuarine, and aquatic systems.
Looking for a specific compound or parameter? See our full analyte index covering PFAS, PAHs, PCBs, metals, VOCs, and every other panel we sample for.
CMA provides specialized field services supporting PFAS site investigations, including porewater sampling, sediment characterization, and groundwater-surface water interaction studies relevant to PFAS fate and transport at contaminated sites.
Our field capabilities are well-suited to support PFAS remedial investigations at DoD facilities and industrial sites where groundwater discharge to surface water bodies is a concern.

Our technologies provide the basis for targeted sampling of porewater in groundwater discharge zones, thin layer caps, and general areas of near shore sediments. We have pioneered small volume sampling with the Trident Probe with application to VOCs, metals, PAHs, and PCBs.
We can also provide services for preparing and installing a range of passive samplers for porewater assessment, including peepers, diffusion samplers, and other emerging passive sampling technologies.
CMA specializes in mapping groundwater discharge zones in surface water systems. We have unique capabilities and extensive experience that spans a broad range of sites including bays, harbors, estuaries, lakes, and rivers.
We can tailor a cost-effective study to meet your requirements and provide the best data possible to support your environmental decisions. Our Trident Probe system provides rapid identification and mapping of discharge zones through integrated temperature, conductivity, and grain-size screening.
Our unique ultrasonic seepage meters provide the capability to quantify groundwater seepage over a broad range of discharge rates and conditions — ranging from very low discharges in lakes to strong and periodic discharges in tidally influenced coastal environments.
We can use these systems in combination with porewater measurements or flow proportional seepage sampling to quantify freshwater, seawater, nutrient, and contaminant flux rates. Our UltraSeep technology provides time-series data over tidal cycles of groundwater flow, contaminant concentration, and associated sensor data.
We have a broad range of experience and equipment to support shallow water sediment sampling activities including grab sampling, core sampling, and diver-collected samples. We also have sediment sampling capabilities that adapt to our drive frames and fast water sampling systems.
Our capabilities include standard and specialized core collection, processing, and subsampling for chemical analysis, grain size analysis, and bioassay exposures.
