MAS is fully functional as an essential business. Our offices are not currently open to the public. However, we are adhering to the recommended social distancing guidelines and have created a safe working environment in our offices by initiating screening practices, moving office spaces further apart and requiring the use of masks at all times. We are also allowing employees to work from home. In addition, our field staff are able to use separate vehicles, have access to hand sanitizers, and are required to use masks at all times

PFAS Assessment and Remediation

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) describe a class of nearly 5,000 manmade chemicals suspected of causing adverse health outcomes in humans. PFAS are known as “forever” chemicals because they persist in the environment and in the human body. PFAS may  

be found in military bases, airports, seaports, dry cleaners, manufacturing sites, landfills, bio solid disposal sites, and in local water supplies. PFAS are also commonly found in every American household and in products ranging from nonstick cookware, stain-resistant furniture and carpets, wrinkle-free and water-repellent clothing, cosmetics, lubricants, paint, and food packaging. PFAS have been legally used for decades and even mandated for use in certain products, such as firefighting foams commonly used at airports and firefighting training facilities. 

In 2016, the US EPA established a lifetime exposure health advisory level of 70 parts per trillion for the combined concentration of PFOA and PFOS in drinking water. However, most states do not yet regulate PFAS concentrations in groundwater or soil. On February 4, 2021, a revision to Florida Senate Bill 1054 was introduced to include PFAS as a contaminant of concern in the Florida Department of Environmental Protection’s site rehabilitation program.  


Types of PFAS services include: 


  • PFAS Groundwater Sampling  Once the groundwater contamination has been identified, there are a number of options available:
    • Containing the contaminant to prevent migration onto neighboring properties. 
    • Allowing the contaminant to naturally attenuate over time with periodic monitoring. 
    • Leaving the groundwater in place and chemically treating it to reduce or remove the contaminant. 
    • Pumping the water from the ground, treating it and returning it to the ground.  
  • PFAS Soil Sampling – MAS conducts soil investigations to determine not only if contamination is present beneath site, but also to determine the extent of contamination.  Our geologists and technicians regularly perform subsurface sampling activities by strategically calculating boring locations in order to best assess the property’s condition.  Once the boring locations have been determined, MAS will perform or oversee all field work and machinery used by personally selected subcontractors. Soil samples will be submitted to an approved environmental laboratory for analyses for PFAS. Based on the soil analytical results, MAS will recommend the next course of action, which may include soil excavation, chemical injection or remedial system design. 


New information and guidance continues to emerge about PFAS and sampling protocols. MAS ensures that our personnel and our subcontractors maintain the most up to date training, experience, and credentials necessary to provide our customers with proper consultations, testing, and site rehabilitation services. All sampling and remediation activities are performed in strict compliance with the local, state and federal rules and regulations.
