  2. The Emerging Threat: Per- & Polyfluoroalkyl Substances (PFASs)

    • PFAS have been described by the US Centre for Disease Control as “one of the most seminal public health challenge for the next decades” with drinking water standards tumbling to 13 ng/L in New Jersey, 12 ng/L New Hampshire, 10 ng/L in New York and 8 ng/L in Michigan (PFOA), 3 ng/L for PFOS in Denmark;
    • PFAS comprise manmade chemicals that are extremely persistent (termed forever chemicals), mobile, and toxic which can bioaccumulate in humans by >1000 fold, partitioning to blood and the liver by interactions with protein. They contaminant drinking water supplies and have been termed the “toxic trespass” as they have often been present in drinking water for decades untested;
    • Certain PFAS have been linked to high cholesterol, ulcerative colitis, thyroid disease, testicular cancer, kidney cancer, and pregnancy-induced hypertension.

  5. Lunch and Networking

  6. Achieving Stringent Targets for Chlorinated Solvents: treatment with electron-donor substrates and injectable colloidal activated carbon

    • Remedial targets for chlorinated solvent plumes are often stringent, particularly when receptors are located close to the site.
    • In situ remediation through slow-release electron donor substrates and injectable colloidal activated carbon is viable.
    • Hear about design, application and validation data from an ongoing project on a 60,000m2 site in Italy.

    Managing Director, REGENESIS
  7. An Adaptive Remediation Strategy to Mitigate Biofouling in a Hydraulic Containment and Ex-situ Treatment System

    • How a remedial approach was developed at a chlorinated solvent impacted fractured bedrock site, using a Hydraulic Containment System (HCS) to break contaminant migration pathways;
    • Challenges identified during initial operation of the HCS, where a complex and unexpected combination of organic, inorganic and microbial contaminants was identified;
    • How an adaptive strategy has been implemented to respond to these issues and achieve the project objectives.

    Technical Director, ERM
  8. Sustainable Remediation or a Jail Free Card

    • CLR 11 and SuRF-UK frameworks - what are the differences;
    • Risk and sustainability are mutually exclusive so that risk cannot be compromised by the sustainability;
    • Mythbusting the concept of “do nothing is acceptable to manage the risk”.
