Effective Remediation of MGP sites

It is estimated that there are over 3,000 former Manufactured Gas Plant (MGP) sites across the United States. Another 4,000 dot the landscape of Canada, the UK, continental Europe and Japan. These sites were built long ago on rivers or harbors, often on the outskirts of towns and cities; locations that are now frequently in close proximity to infrastructure, buildings and residential areas. Many underlie or abut valuable commercial, residential, and municipal properties, posing environmental hazards to ground and surface waters. The urgency of remediation has increased due to a potent blend of community activism, regulatory pressure, high real estate values, and the need to reduce liability in light of the Sarbanes-Oxley Act and other measures.

TerraTherm’s in situ thermal remediation technologies offer you several advantages for the remediation of your MGP sites:

  • Achieve your cleanup goals, even to residential standards;
  • Obtain excellent ROI, eliminate liability and increase your property value;
  • Remove mobile volatile organic compounds, such as benzene and naphthalene that often drive site risk;
  • Prevent migration beyond property boundaries, and protect water bodies;
  • Allow ongoing commercial activities on site;
  • Applicable beneath buildings and near structures such as roads and bridges, and where other physical features cannot be disturbed;
  • Work above and below the water table;
  • Applicable to many soils including silty clay layers and heterogeneous soils with wide variations in permeability and water content, and in fractured rock; and
  • Significantly reduce long-term operations and maintenance costs of traditional pump and treat systems.
