Maryland Port Administration
Statewide, Maryland

The Maryland Port Administration (MPA) manages the State's public marine terminals. Since 1986, EA has supported MPA with wide ranging services involving environmental compliance, permitting, and feasibility support related to Chesapeake Bay natural resources.

environmental monitoring and construction management servicesENVIRONMENTAL MONITORING

Poplar Island Environmental Restoration Project—This 1,100-acre, beneficial use island restoration project is designed to restore 550 acres of upland habitat and 550 acres of wetland habitat using dredged material from the Bay approach channels to the Port of Baltimore. EA assisted MPA, U.S. Army Corps of Engineers, and regional regulatory agencies in developing and implementing an exterior monitoring program. The physical, chemical, and biological data resulting from each monitoring component feed into an adaptive management framework for the overall restoration effort.

EA collects and evaluates data on sediment quality, water quality, benthic communities, epibenthic communities, and chemical concentrations in benthic tissue (clams). Water, sediment, and benthic tissue are tested for organic (e.g., pesticides) and inorganic (e.g., metals) constituents. Statistical analysis of the data compares pre- and post-placement conditions in light of Chesapeake Bay Restoration Goals. The results of monitoring and adaptive management at the Poplar Island Environmental Restoration Project will help guide future Chesapeake Bay island restoration initiatives.

Masonville Dredged Material Containment Facility (DMCF) – Turbidity Monitoring During ConstructionThe Masonville DMCF is located on the Middle Branch of the Patapsco River in Baltimore Harbor, Maryland. EA conducted turbidity monitoring to determine the extent of in-water sediment plumes resulting from construction-related dredging operations. During construction, real-time turbidity monitoring was conducted for 5 of every 7 days to assess compliance with applicable State of Maryland water quality regulations. An acoustic Doppler current profiler (ADCP) was used to locate plumes and a portable turbidity meter was used to measure turbidity. Data were updated daily to a password-protected website for review by construction management personnel and environmental regulators.
