In recent years, the issue of environmental contaminants has gained significant attention, particularly in the realm of stormwater management. Phrases like PFAS (per-and polyfluoroalkyl substances) and microplastics have become synonymous with water pollution. It is crucial for superintendents in the stormwater industry to have a comprehensive understanding of these contaminants and their impact on water quality. This ultimate guide aims to provide a detailed overview of PFAS and microplastics, their relationship with the stormwater industry, mitigation strategies, regulatory compliance, and future trends and innovations.
Understanding PFAS and Microplastics
What are PFAS?
PFAS, also known as "forever chemicals," are a group of man-made substances that have been widely used in various industrial and consumer products for several decades. They are particularly valued for their resistance to heat, water, and oil. Unfortunately, this durability has led to their persistent presence in the environment, posing a significant threat to both human health and ecological systems.
PFAS can be found in a multitude of products, including firefighting foams, non-stick cookware, waterproof textiles, and food packaging. Due to their widespread use and resistance to degradation, PFAS have infiltrated water sources, resulting in contamination of drinking water supplies and aquatic environments.
When it comes to human health, exposure to PFAS has been linked to various adverse effects. These include developmental issues in infants and children, decreased fertility, increased cholesterol levels, immune system dysfunction, and an increased risk of certain types of cancer. The persistence of PFAS in the environment means that even if their use is discontinued, their impact will continue to be felt for years to come.
Efforts are being made to address the issue of PFAS contamination. These include the development of alternative chemicals that are less harmful, as well as the implementation of stricter regulations on the use and disposal of PFAS-containing products. However, the widespread nature of PFAS contamination presents a complex challenge that requires a multi-faceted approach involving government agencies, industries, and individuals.
The Impact of Microplastics
Microplastics are tiny plastic particles measuring less than 5mm in size. They are derived from the breakdown of larger plastic items or are intentionally manufactured for certain products. Microplastics pose a grave threat to aquatic life, as they can be mistakenly consumed by organisms at various trophic levels, ultimately impacting the entire food chain.
The sources of microplastics are numerous, including microbeads in personal care products, synthetic fibers from clothing, and the fragmentation of larger plastic debris. Stormwater runoff acts as a major transport pathway for microplastics, carrying these particles from urban areas into rivers, lakes, and oceans. The accumulation of microplastics in water bodies has raised concerns about their potential to enter the human food chain and cause adverse health effects.
Studies have shown that marine animals, such as fish, seabirds, and marine mammals, can ingest microplastics, mistaking them for food. This ingestion can lead to physical harm, as the sharp edges of microplastics can damage the digestive tract of these animals. Additionally, microplastics can contain toxic chemicals that can be absorbed by the organisms, leading to further health complications.
Furthermore, the presence of microplastics in aquatic environments can have ecological consequences. These particles can alter the behavior and reproductive patterns of marine organisms, disrupt the balance of ecosystems, and contribute to the decline of certain species. The long-term effects of microplastic pollution on marine biodiversity are still being studied, but the evidence so far suggests that urgent action is needed to mitigate this problem.
In recent years, there has been a growing awareness of the issue of microplastic pollution, leading to efforts to reduce plastic waste and develop sustainable alternatives. These include the banning of microbeads in personal care products, promoting the use of biodegradable materials, and implementing recycling programs. However, addressing the problem of microplastic pollution requires a collective effort from governments, industries, and individuals to reduce plastic consumption, improve waste management practices, and protect our oceans and aquatic ecosystems.
The Role of Superintendents in the Stormwater Industry
The role of a superintendent in the stormwater industry is pivotal in ensuring the effective management and protection of stormwater systems against contaminants like PFAS (per- and polyfluoroalkyl substances) and microplastics. With their expertise and knowledge, superintendents are responsible for overseeing the operation, maintenance, and inspection of various stormwater infrastructure.
One of the key responsibilities of a superintendent is the management of detention basins. These basins are designed to temporarily store stormwater runoff, allowing for the settling of sediments and the removal of pollutants. Superintendents ensure that these basins are functioning properly and are regularly maintained to prevent any potential issues.
In addition to detention basins, superintendents also oversee the maintenance and inspection of drainage systems.

The Intersection of PFAS, Microplastics, and the Stormwater Industry
How PFAS and Microplastics Enter Stormwater Systems
Stormwater systems are highly susceptible to the entry of PFAS and microplastics due to their widespread presence in the environment. PFAS compounds can leach from landfills, industrial sites, and firefighting training areas when rainwater runoff occurs. This runoff carries the PFAS compounds into stormwater systems, where they can accumulate and pose a threat to water quality.
In addition to leaching, direct spills or improper disposal of PFAS-containing products can also lead to contamination of stormwater systems. For example, if a fire suppression foam containing PFAS is accidentally spilled near a storm drain, the foam can easily flow into the drain and enter the stormwater system.
Microplastics, on the other hand, enter stormwater systems through various pathways. They can be washed off streets and parking lots by rainfall, as well as transported through storm drains. Once in the stormwater system, microplastics can eventually be discharged into receiving waters, where they can have detrimental effects on aquatic ecosystems.
Another significant source of microplastics in stormwater is wastewater treatment plants. These treatment plants are designed to remove solid particles from wastewater before it is discharged into the environment. However, some microplastics are too small to be effectively removed by the treatment process, leading to their presence in the effluent and subsequent entry into stormwater systems.
The Effects of PFAS and Microplastics on Stormwater Quality
PFAS and microplastics pose significant risks to stormwater quality and the ecosystems it supports. When PFAS compounds accumulate in sediments, they can potentially lead to bioaccumulation in aquatic organisms. This bioaccumulation can have cascading effects on the food chain, as predators that consume contaminated organisms may also become contaminated.
Furthermore, the presence of PFAS in stormwater can impair its ability to recharge groundwater. PFAS compounds are known to be persistent and can remain in the environment for long periods of time. As a result, stormwater that is contaminated with PFAS may not be suitable for recharging groundwater, which can have implications for water availability in the future.
Microplastics in stormwater can cause physical blockages in drainage infrastructure, leading to reduced efficiency and increased maintenance costs. These tiny plastic particles can accumulate in storm drains and pipes, gradually reducing their capacity to carry water. This can result in localized flooding during heavy rainfall events and increased costs for municipalities to clean and maintain the stormwater infrastructure.
Additionally, microplastics have toxic effects on aquatic flora and fauna. The ingestion of microplastics by aquatic organisms can lead to physical harm and even death. Furthermore, the presence of microplastics in water bodies can disrupt the balance of the ecosystem, affecting the abundance and diversity of species. This disruption can have far-reaching consequences for the overall health and functioning of the ecosystem.
Moreover, the compromised water quality resulting from the presence of microplastics in stormwater can have implications for human use. If the stormwater is used for irrigation or other purposes, the microplastics can contaminate crops or other agricultural products, potentially entering the human food chain. Additionally, if the stormwater is eventually treated for drinking water purposes, the presence of microplastics can pose challenges for the treatment process and the quality of the final drinking water product.
