Remedial Design & Implementation

Our experts design PFAS analysis solutions and risk reduction strategies that optimize resources – whether it’s a single residential point-of-entry or complex remedial system. Our understanding of the regulatory climate and potential risks leads to data-informed business decisions that accomplish agreed upon goals. We can also PFAS contaminated water treatment, self-implement soil, groundwater, and drinking water remedial solutions, and act as Client Representatives – to manage procurement and construction QA oversight of contractors to ensure all objectives are met.

Exposure & Health Risks

Montrose has toxicological expertise and risk communication experience in chemical sampling, contamination documentation, environmental data analysis, and emergency response guidelines which are instrumental in identifying potential exposures and risk factors. From human health risk assessments and toxicology, to analytical method and screening level development, and risk communication and community engagement, we provide qualitative and quantitative, PFAS-focused evaluations.

Project Quality Oversight

Our team builds data quality into any PFAS program by establishing the ideal analytical methods and coordinating field sampling and analytical activities. Our quality assurance chemists validate laboratory data as well as audit laboratories to assure data defensibility. And when the data are suspect, we have decades of experience performing PFAS forensic chemistry to resolve any anomalies.

Testing & Analysis

Our Ultratrace laboratory can analyze for over 70 PFAS compounds, including legacy PFAS (such as PFOS/ PFOA) and newer PFAS (such as GenX). We obtain accurate and precise results by using as many isotopically labeled internal standards as possible (i.e. isotope dilution technique).

AFFF Changeout and Treatment

Our team is uniquely qualified in lifecycle solutions for the replacement, treatment, and disposal of aqueous film-forming foam (AFFF) systems for the DoD, government, and industrial clientele. We partner with our clients on each unique site to identify the approach that best meets objectives for cost, regulatory liability, and future use of AFFF systems that contain the emerging chemical known as per-and polyfluoroalkyl substances (PFAS). Typical work elements include: 

• draining and containerizing waste AFFF concentrate
• decontaminating and flushing (with water or solvents/detergents) AFFF tanks, hydrants, and piping
• containerizing rinsate
• treating concentrate and rinsate and discharging to storm or sanitary sewer
• managing waste disposal of liquids and solids
• modifying fire protection systems
• replenishing with new foam formulations or water systems
• providing regulatory consulting and employee toxicology and exposure assessments 

Our work is closely controlled and monitored primarily through our in-house disciplines and capabilities, including environmental technicians, engineers, industrial hygienists, and chemists. Additionally, we have in-house certified PFAS laboratories and onsite PFAS treatment technologies using a variety of treatment options, such as foam fractionation, granulated activated carbon, and ion exchange resin systems capable of treating liquid waste to non-detect levels.
