Marine Terminal, California
Problem: The integrity of the existing sea wall at a marine terminal was questionable and required enhancement to ensure that impacted groundwater underneath the facility did not adversely impact seawater quality of the marine environment.
Strategy: Working closely with multiple Federal and State agencies, a barrier of plastic sheet pile and permeation grout was designed. The barrier was enhanced by a system of hydraulic control wells.
Result: The installed combination barrier of plastic sheet pile and permeation grout successfully mitigated contaminant migration to seawater and was supplemented with recovery wells installed behind the barrier to maximize the hydraulic control of the local groundwater.
