The purpose of the vibracore sampling operations and laboratory analysis was to verify the quality and quantity of material remaining within an offshore borrow area which will be used for the Kure Beach Storm Damage Reduction Project. For this effort, we collected 39 vibracores to 20’ which was completed in May 2018. e. (1) TITLE AND LOCATION (City and State) (2) YEAR COMPLETED Kerr-McGee Chemical Corp Superfund Site Jacksonville, Florida PROFESSIONAL SERVICES CONSTRUCTION (If applicable) 2018 BRIEF DESCRIPTION (Brief scope, size, cost, etc.) AND SPECIFIC ROLE Check if project performed with current firm Mr. Simmons served as the captain on this project for American Vibracore Services (AVS), a marine division of Amdrill Inc. As a former chemical site manufacturing fertilizers, pesticides and herbicides, environmental and geotechnical investigations were necessary to delineate the nature and extent of site rel ated compounds and evaluate risks associated with these compounds. Given the possible chemical, physical and biological hazards associated with the field investigations, strictly adhering to established safety protocols was mandatory. Our role was to conduct the geotechnical investigations by performing vibracoring utilizing our Scully barge for these environmentally challenging core and grab samples, plus, performing land borings. f. (1) TITLE AND LOCATION (City and State) (2) YEAR COMPLETED Vibracore Borings and Laboratory Testing St. Johns County, Florida PROFESSIONAL SERVICES CONSTRUCTION (If applicable) 2017 BRIEF DESCRIPTION (Brief scope, size, cost, etc.) AND SPECIFIC ROLE Check if project performed with current firm Mr. Simmons served as the captain on this project for American Vibracore Services (AVS), a marine division of Amdrill Inc. For St. Johns County’s shore protection project in St. Augustine Beach, a sand search investigation was performed by collecting vibracores within the proposed offshore borrow area. T he work was performed within state waters, off the southeast coast of Florida, approximately 30 miles south of Jacksonville and adjacent to the city of St. Augustine, Florida. Vibracore sampling occurred at two locations. Twelve borings were collected on the eastern edge of the St. Augustine Inlet ebb shoal and twelve additional borings were collected approximately 1 to 2 miles offshore of the town of Vilano Beach. Water depths in these areas were approximately 30 to 60 feet. g.

Vibracore sampling operations were conducted in the Lake Worth Lagoon intracoastal waterway to determine the characteristics of collected sediments in support of a channel dredging project. A shallow platform and vibracore equipment were used for the near shore operations. A total of 6 vibracores to depths of -6 MLW or until refusal were collected to within 50 feet of the proposed locations. Sediments sampled were split, logged, photographed, sampled and preserved.
