PFAS – Poly and Perfluorinated Alkyl Substances

Poly- and Perfluorinated Alkyl Substances, or PFAS, are a large group of manmade chemicals with useful physical properties. These properties include resistance to high temperatures and stability. PFAS also repel water, oils, and other chemicals.

These properties have resulted in the manufacture of numerous industrial, commercial, and consumer products. Examples include firefighting foam, non-stick coatings, water and oil-resistant fabrics, and a host of other applications and products.

These properties have a negative impact on the environment. Since they do not easily break down by natural means, they remain in the environment for long periods of time. When animals or humans accidentally ingest these chemicals, they remain in the body for long periods of time. The compounds have been linked to health issues in humans when exposed even at very low concentrations (parts per trillion).

PFAS are considered an “Emerging Contaminant” and are being investigated nationally where the chemicals were manufactured, used in industry, or disposed.  DLZ has been involved in PFAS investigations and assessments since the early 2000s and is active in site investigation and risk mitigation.

DLZ PFAS Services include:

  • Site Investigations
  • Ecological Studies
  • Soil, Groundwater, Surface Water, and Sediment Sampling
  • Groundwater Modeling
  • Site Remediation

DLZ provides services to evaluate your site for the presence of PFAS contamination, the extent and concentrations of that contamination, and any potential receptors. Impacts on drinking water typically require immediate response to protect the public.  DLZ will work with you to develop a plan to address any identified receptors, mitigate risks, and manage the plan once approved.
