ANAMAR was contracted by USACE Jacksonville District to perform sampling, testing, reporting, and characterization of maintenance and new work dredged material in accordance with MPRSA §103. The purpose of these projects is to determine the suitability of the material for disposal in the San Juan Harbor ocean dredged material disposal site (ODMDS).
The sediment characterization and testing performed for this project includes both routine maintenance of the San Juan Harbor navigation channels to authorized depths and proposed deepening (new work) material in support of future deepening and widening in some areas of the San Juan Harbor. For sampling and testing purposes, the San Juan Harbor project area was divided into five dredging units. Proposed harbor improvements include:
- Deepening of Bar and Entrance Channels;
- Deepening of the Anegado and Army Terminal Channels;
- Deepening of the San Antonio and San Antonio Approach Channels;
- Widening of Army Terminal Channel; and
- Extending the San Antonio Channel in an easterly direction.
The project also included characterization of the Puerto Rico Ports Authority Berthing Areas. This portion of the project was coordinated with the larger San Juan Harbor project to realize efficiencies and cost-savings for the Puerto Rico Ports Authority with regards to mobilization, shipping, and collection and analysis of the offshore reference sample. The sediment characterization and testing performed for this project included evaluation of routine maintenance dredge material in support of operations and maintenance dredging of the berthing facilities in the San Juan Harbor. For sampling and testing purposes, the Puerto Rico Ports Authority Berthing Areas project area was divided into four dredging units.
ANAMAR coordinated and directed operations for this project and worked closely with USACE and EPA to develop sampling and analysis schemes, schedules, and deliverables. ANAMAR also reviewed all data and produced reports summarizing the results of the physical, chemical, and toxicological analyses of sediment samples collected from the project areas.
