In recent years, the contamination of tap water with harmful chemicals known as PFAS (Per- and Polyfluoroalkyl Substances) has become a growing concern for homeowners across the United States. These "forever chemicals" have been found in water supplies nationwide, raising alarms about their potential health risks and the long-term consequences of exposure.

As we enter October, a time often associated with environmental awareness and clean water initiatives, it's crucial for homeowners to understand the impact of PFAS in their drinking water. In this article, we'll explore what PFAS are, how they enter your water supply, the dangers they pose, and, most importantly, how you can protect your family from their harmful effects.

What Are PFAS?

PFAS are a group of over 4,700 synthetic chemicals that have been used in various industries since the 1940s. These chemicals are highly resistant to heat, water, and oil, making them ideal for a wide range of applications. They can be found in products such as:

• Non-stick cookware
• Water-repellent clothing
• Stain-resistant fabrics
• Firefighting foams
• Food packaging
• Industrial processes

Due to their chemical structure, PFAS are extremely persistent in the environment and human body, earning them the nickname "forever chemicals." Once they enter water sources, they can remain there for years, gradually accumulating and posing long-term health risks to those who consume the contaminated water.

How Do PFAS Get Into Tap Water?

PFAS can enter water supplies through various pathways. Some of the primary sources include:

1. Industrial Discharge
   Factories that produce or use PFAS in manufacturing often discharge wastewater containing these chemicals into nearby rivers, lakes, and groundwater. Over time, these chemicals seep into public water systems.
2. Firefighting Foam Runoff
   PFAS-containing firefighting foams are used in airports, military bases, and industrial sites to combat fuel-based fires. When these foams are sprayed, the chemicals can run off into nearby water sources, leading to contamination.
3. Landfills and Waste Sites
   Products containing PFAS often end up in landfills, where the chemicals can leach into the soil and contaminate groundwater supplies. Similarly, waste disposal sites that handle PFAS-related materials can contribute to the contamination of local water systems.
4. Agricultural Runoff
   In some cases, PFAS can enter water supplies through agricultural runoff. Fertilizers, pesticides, and other agricultural chemicals may contain PFAS, which can wash into rivers and lakes during rainfall, affecting the water that reaches our taps.

Health Risks of PFAS Exposure

The presence of PFAS in tap water is concerning because these chemicals have been linked to several serious health problems. Prolonged exposure to PFAS, even at low levels, can lead to a range of health issues, including:

1. Cancer
   Studies have shown a correlation between PFAS exposure and certain types of cancer, including kidney, liver, and testicular cancer. PFAS have also been classified as "likely carcinogenic" by the International Agency for Research on Cancer (IARC).
2. Hormonal Disruption
   PFAS are known to interfere with the endocrine system, which regulates hormones in the body. This disruption can lead to reproductive issues, developmental problems in children, and complications during pregnancy.
3. Immune System Suppression
   PFAS exposure has been linked to weakened immune function, making individuals more susceptible to infections and illnesses. Some research also suggests that PFAS may reduce the effectiveness of vaccines.
4. Liver and Kidney Damage
   Prolonged PFAS exposure can damage vital organs such as the liver and kidneys. This can result in conditions like liver disease, kidney dysfunction, and elevated cholesterol levels.
5. Developmental Effects in Children
   Children and infants are particularly vulnerable to the effects of PFAS exposure. Studies suggest that PFAS may contribute to low birth weights, developmental delays, and learning disabilities.
6. Thyroid Disease
   PFAS can interfere with thyroid hormones, potentially leading to thyroid disease and other metabolic disorders. This can have long-term effects on energy regulation, weight, and overall health.

Current PFAS Regulations

The growing awareness of PFAS contamination has led to increased efforts to regulate and limit these chemicals in drinking water. However, there is still much work to be done at both the federal and state levels to fully address the issue.

1. EPA Guidelines
   In the United States, the Environmental Protection Agency (EPA) has set health advisory levels for two common PFAS chemicals, PFOA and PFOS, at 70 parts per trillion (ppt) in drinking water. However, these advisory levels are not legally enforceable, meaning public water systems are not required to comply.
2. State-Level Regulations
   Some states have taken the initiative to establish their own PFAS drinking water standards. For example, Michigan, New Jersey, and Vermont have set limits much lower than the EPA's advisory level, ranging from 8 ppt to 20 ppt for certain PFAS chemicals.
3. Proposed Federal Action
   In recent years, there have been calls for stronger federal regulations on PFAS. In March 2023, the EPA proposed new regulations that would require water utilities to test for and limit PFAS in drinking water. If these regulations are finalized, they could significantly reduce PFAS exposure nationwide.

How to Test Your Tap Water for PFAS

If you're concerned about the presence of PFAS in your tap water, the first step is to test it. There are several ways to determine whether your water is contaminated with these chemicals:

1. Request a Water Quality Report
   Public water systems are required to provide annual water quality reports to consumers. These reports, also known as Consumer Confidence Reports (CCRs), outline the levels of various contaminants, including PFAS, in your drinking water. If PFAS are not listed in the report, you can contact your water provider for more information.
2. At-Home Testing Kits
   There are at-home testing kits available that can detect the presence of PFAS in your tap water. These kits typically involve collecting a water sample and sending it to a certified lab for analysis. The lab will then provide you with a detailed report on the PFAS levels in your water.
3. Hire a Professional Testing Service
   If you're unsure about the accuracy of at-home kits or want more comprehensive testing, you can hire Dupure to perform a professional water testing service. These services use advanced techniques to measure PFAS levels and provide detailed recommendations on how to address contamination.

How to Remove PFAS from Tap Water

Once you've confirmed the presence of PFAS in your tap water, it's essential to take action to remove them. While PFAS are challenging to eliminate due to their chemical resistance, there are several effective methods for reducing their levels in your drinking water:

1. Activated Carbon Filters
   Activated carbon filters, such as those used in Dupure systems, are highly effective at reducing PFAS from tap water. These filters work by trapping PFAS molecules as water passes through, significantly reducing the concentration of the chemicals. It's important to replace the filters regularly to maintain their effectiveness.
2. Reverse Osmosis Systems
   Reverse osmosis (RO) systems are another reliable method for removing PFAS from drinking water. RO systems use a semipermeable membrane to filter out contaminants, including PFAS. This technology is highly effective but can be more expensive and requires regular maintenance to function properly.
3. Ion Exchange Resins
   Ion exchange resins are specialized filters that can remove PFAS by exchanging charged particles in the water. While effective, this method is typically used in large-scale water treatment facilities and may not be practical for individual households.
4. Whole-House Filtration Systems
   If you're concerned about PFAS exposure from all water sources in your home, consider installing a whole-house filtration system. These systems treat water as it enters your home, ensuring that every tap delivers filtered, PFAS-free water. Dupure offers whole-house solutions designed to target contaminants like PFAS, providing peace of mind for homeowners.
