Challenges of Treating PAH Compounds Down to Part Per Trillion Levels on a Remediation Site
Down to Part Per Trillion Levels on a Remediation Site
As discharge regulations continue to tighten across North America, solution providers are required to evolve and adapt products and designs to meet new regulations.
In 2015, newterra developed a process design and created a treatment plant for remediating a heavily contaminated Superfund site situated on the environmentally sensitive shore of Lake Superior. As a former Manufactured Gas Plant (MGP), the site contained large volumes of weathered LNAPL and DNAPL that were collected and treated along with the heavily impacted groundwater and solids drawn from multiple extraction wells on the property.
The effluent from the treatment plant discharged to Lake Superior and was subject to strict permit requirements with discharge limits in the part per trillion range for the difficult to treat PAH compounds.
This presentation will guide the audience through the treatment objectives and challenges faced in developing the solution for this site. The presenter will walk through the process steps of bench testing, pilot testing and full scale design of the treatment plant – and share the lessons learned through commissioning and startup.
By sharing our challenges, technology selection process and experience from this project, delegates will be able to apply and build on the lessons we learned for their own remediation/water treatment initiatives.
