Sediment and Water Monitoring

Versar's staff has extensive experience collecting sediment samples from deep-water using benthic grabs or a vibracore; inlet pipes of confined disposal facility; and a variety of other sources. Versar has conducted dozens of sediment contamination studies for USACE and commercial clients. We have expertise in all aspects of testing requirements and interpretation of the results. Testing needs for dredging projects often include monitoring the dewatering discharges from upland dredge material disposal facilities. Versar uses programmable automatic samplers, flow data loggers, and sophisticated laboratory analysis techniques to perform this task efficiently and economically.

Recent Projects:

Dredge Contaminant Testing – Conducted water quality monitoring downstream of hydraulic dredge cutter head and from the disposal site for the Delaware River Deepening Project

Rhodamine Dye Study – Estimated the water outflow residence time at the Fort Mifflin Confined Disposal Facility in Pennsylvania by injecting dye and monitoring discharge concentrations

Sediment Testing – Conducted bulk contaminant and elutriate testing on vibracore samples of Schuylkill River bottom sediments to estimate releases to the water column
