Text from the 2019 sediment report: Analytical results indicate that approximately 17.27 acres of GGB contain mercury-impacted sediment at concentrations exceeding the mercury MPBC of 0.36 mg/kg. The modeling effort estimated an in-place sediment volume of 54,120 cubic yards that exceeded the MPBC. The Army is currently evaluating remediation technologies to address the impacted sediment in the GGB.
