Engineering and Remedial Design services

WSP Environment & Energy's engineering team brings comprehensive regulatory, site characterization, engineering, and construction experience to each project, whether it is for cost evaluation, a feasibility study, or detailed design.

Our engineers follow their designs to the field, where they provide the construction oversight and monitoring, which ensures the designs are implemented properly. This first-hand knowledge provides the experience required to ensure we provide our clients with innovative designs that are not only cost effective but also readily implemented. It also ensures that the cost estimates we develop reflect the real costs of the project rather than generic unit rates pulled from general industry references.

Remediation and reclamation of former lead mining Superfund site

WSP was retained by Baxter Springs to provide remedial design and construction oversight services for a former lead mining Superfund site in Cherokee County, Kansas. These services were essential in order to fulfill the remedial action objectives specified in the Record of Decision. Large scale mining on the site had resulted in heavy metals (primarily lead, cadmium, and zinc) and contamination of soil, sediments, groundwater, and surface water. An estimated 1,250 acres were covered with surficial mining/mill waste piles, tailings impoundments, and stream outwash tailings deposits.

WSP’s remedial design approach incorporated sustainable alternatives to minimize costs and reduce energy requirements. WSP also performed construction management services for PRP Group for the site. In addition, WSP negotiated future land use restrictions and long-term access agreements with the property owners on behalf of the Group. The work was completed well within schedule and WSP continues to perform routine operation and maintenance inspections at the site.

Investigation and interim actions at a Superfund Site, Florida

WSP has been working with the Florida Department of Environmental Protection and the U.S. Environmental Protection Agency to investigate and remediate the environmental conditions of a 1,000-acre former phosphate mining site in Central Florida. WSP conducted a comprehensive site investigation and analyzed and characterized sediments. This included an innovative design for capping sediments rather than excavating and consolidating them which resulted in significant cost savings. This design was awarded the Outstanding Achievement Award by the Industrial Fabrics Association International.

In 2007, the site entered the Superfund program. WSP is now working with the client to characterize radionuclide activity concentrations and providing technical solutions for demonstrating that radionuclides are not migrating from the site. A Record of Decision is scheduled for early 2011, and WSP is working with the client to identify cost-effective containment and consolidation approaches for remediation of the various affected media.

In-situ remediation of industrial facility, Georgia

WSP Environment & Energy was retained to investigate and remediate soil, perched water, and groundwater at a former wire shelving manufacturing facility in southeastern Georgia. The facility was contaminated due to leaks from a sulfuric acid rinse water sump and chromic acid sump as well as a release of plating rinse water. WSP conducted soil and groundwater investigations and successfully designed and executed an in-situ remedial solution to reduce the hexavalent chromium concentration in the perched water. WSP also excavated and removed soil and perched water from the site. Based on the success of the remediation, the Georgia Environmental Protection Division (EPD) delisted the site from the state Hazardous Site Inventory and allowed the client to discontinue any future monitoring.

In-situ bioremediation of manufacturing facility, Statesboro, Georgia

At a central Georgia manufacturing facility, a historic release of coolant containing chlorinated solvent resulted in a 1200-foot long dissolved volatile organic compound (VOC) plume. WSP was commissioned to perform the investigation and characterization of the site as well as design and implement the remedial program. Using the application of molecular biological tools (MBTs), WSP demonstrated that the plume was stable as a result of natural attenuation. To minimize the remedial timeframe and gain regulatory approval for monitored natural attenuation, source area soils and source area groundwater were targeted for active remediation. Source area soil excavation and groundwater chemical oxidation were the technologies selected for these areas of concern. The integrated remediation approach, defined as source treatment plus MNA, was approved by the Georgia Environmental Protection Division. This integrated remediation approach is estimated to have saved the client between $700,000 and $1,700,000.
