PFAS regulations are rapidly evolving at the state and federal levels. PFAS concerns have added complexity to real estate and business transactions. Kleinfelder’s team of professionals advise clients on transactional due diligence and latest assessment best practices such as American Society for Testing and Materials (ASTM) E1527-21 Standard Practice for Phase I Environmental Site Assessments. Kleinfelder routinely performs transactional and non-transactional PFAS due diligence to assess potential PFAS impacts in various media and manage potential risks.

Regulatory Compliance

Kleinfelder’s regulatory compliance professionals provide a range of services related to PFAS, including compliance monitoring and testing, subsurface drilling, discharge permitting, stormwater and spill planning, and compliance with reporting requirements under various federal and state statutes.

Environmental Remediation

Kleinfelder delivers long-term strategies and sustainable solutions that achieve our clients’ objectives while mitigating or offsetting potential impact to the natural environment and our communities. Our teams are involved with testing and pilot innovative and cutting edge PFAS separation, sequestration, and destruction technologies for water and soil. Backed by a deep bench-strength of multidisciplinary professionals in geotechnical, water, wastewater, and civil engineering, we can efficiently design and implement practical and effective solutions for complex environmental remediation projects involving PFAS and co-contaminated mixtures.

Fate & Transport Analysis

We recognize that PFAS have unique and varying properties that influence their behavior in the environment. Understanding PFAS interaction with the natural environment and co-contaminant present is vital to develop a comprehensive fate and transport model to understand where sources and receptors may be located and evaluating potential remedial alternatives. We have extensive experience assessing chemical fate and transport with appropriate investigative, analytical, and modeling tools.

Risk Analysis

Kleinfelder leverages the principles of risk analysis and risk management to bring value to various client projects. Specifically, our risk analysis and toxicology solutions focus on human health risk assessment (HHRA) applied to commercial, industrial, or federal sites. As PFAS toxicological studies advance and new standards are published at the state and federal levels, Kleinfelder’s HHRA professionals critically review the basis for these standards and interpret the implications for our clients’ regulatory obligations and liabilities.

Drinking Water

Kleinfelder is focused on providing clean and sustainable water treatment solutions for small and large communities alike. We work with our clients to develop customized and optimized solutions that provide near-term PFAS water quality improvement and long-term sustainability. We have experience in granular activated carbon (GAC), ion exchange (IX), and innovative alternative treatments using surface-modified clay.

Wastewater & Biosolids

Kleinfelder has supported our clients in successfully completing wastewater treatment facilities and upgrades for decades. The evolution of PFAS concerns has created uncertainty within the wastewater management and biosolids communities. Our PFAS professionals work seamlessly with our wastewater project teams and clients to provide sampling and analysis, pollutant minimization plans, industrial pretreatment program support, and PFAS treatment alternatives for both wastewater and biosolids.

Custom Modular Systems

Kleinfelder offers custom-designed packaged PFAS treatment systems for environmental remediation, industrial water, and municipal well-head drinking water systems. We provide turn-key solutions with design, installation, start-up, and operations. Through our water technologies teams, Kleinfelder Water Technologies, we can create a system that meets custom needs.
