Toxic, Mass Tort and Environmental Law

Cowles & Thompson defends corporate clients whose actions or products are alleged to have caused bodily injury or disease; serious harm to the environment; and represents individuals and businesses whose property or property rights are at stake due to environmental concerns. For over thirty years we have represented clients in a wide range of industrial sectors.

Technical understanding of the subject matter is critical to the defense of any toxic tort or environmental law claim, and our attorneys are experienced not only on the litigation side, but also in dealing with experts such as toxicologists, epidemiologists, medical experts and others associated with scientific and medical causation issues. Additionally, our insurance coverage attorneys are experienced in representing clients in declaratory judgment actions regarding the applicability of environmental coverages; and we provide advice to insurance companies on environmental underwriting issues.

Our attorneys frequently defend cases involving:

  • Silica
  • Asbestos
  • Mold
  • Chemical exposures
  • Dental amalgam (mercury)
  • Environmental injury
  • Water runoff
  • Contractual indemnity
  • Insurance coverage
