The report will be <br /> consistent with the requirements for the Quarterly Report, as detailed in the MRP. The <br /> quarterly report will also document all other field activities, such as installation of <br /> monitor wells that occurred during the quarter. <br /> 5. CONCLUSIONS <br /> Preliminary evidence (ERS, 2013) indicates that placement of dredge spoils at MO-1 <br /> does not present an unacceptable risk to human health or the environment. This work <br /> plan builds on this previous investigation by outlining a sampling strategy that seeks to <br /> accurately characterize the attenuation capacity of foundation soils at MO-1 as well as <br /> the quality of local ground water, to allow for an accurate estimation of the risks posed <br /> by establishing MO-1 as a permanent dredge placement facility. <br /> September 2014 12 Environmental Risk Services P r <br /> Corporation <br />
