Abstract:

This project was the final phase of a three-phase project. The primary objective was to determine the suitability of recycled concrete aggregate (RCA) from road projects as a bottom conditioning material for on-bottom oyster aquaculture in the Chesapeake Bay. This third phase project evaluated RCA for petroleum byproducts and provided evaluation methodologies. The results showed that RCA as a base material for oyster reefs did not leach any hydrocarbon chemicals and no water extractable SVOC was detected from RCA following EPA 1316 extraction. Low levels of anthracene, fluorine, phenanthrene and pyrene were detected in samples collected from Machado Construction Co., Inc. and The Recycling Center, but the concentrations were much lower than the State of Maryland Department of the Environment cleanup standard for soil and groundwater. They were at least 100 times below the level considered hazardous in the Protected Groundwater Standard. The project concluded that there was no cause for concern about hydrocarbon components released into the Chesapeake Bay watershed if RCA is used as a bottom conditioning material for oyster aquaculture.
