• Cook with stainless steel, cast-iron, glass, or ceramics. Try not to use nonstick cookware.
• Look for coats, hats, and boots labeled “water-resistant.” They are less likely to have PFAS than waterproof products.
• Avoid ordering food in grease-resistant wrappers or containers.
• Avoid carpets and upholstery treated to be stain or water-resistant; decline stain treatment.
• Ask manufacturers if their products have PFAS. These chemicals are often not listed. However, given that many PFAS cannot be measured yet, products cannot be confirmed “PFAS-free.”
• Filters that are currently available and can be effective at reducing PFAS are Charcoal (Granular Activated Carbon or GAC), Reverse Osmosis (RO) Systems, and Ion Exchange Resins. 

If you are concerned about potential health effects from exposure to these PFAS above the health advisory level, EPA encourages you to contact your doctor or health care professional.

Every five years, the Environmental Protection Agency (EPA) reviews and selects a list of unregulated contaminants for public water systems to monitor. This study benefits the environment and public health by providing valid data on the occurrence of these contaminants in drinking water. The EPA uses this data to develop regulatory decisions for emerging contaminants. This requirement is mandatory for all public water systems that serve more than 10,000 customers.

UCMR5 requires testing for 29 per- and polyfluoroalkyl substances (PFAS) and lithium. This list includes the PFAS chemicals that EPA is proposing new Maximum Contaminant Levels (MCLs): PFOA and PFOS as individual contaminants, as well as PFHxS, PFNA, PFBS and HFPO-DA (commonly referred to as GenX Chemicals) as a PFAS mixture.  

In 2024, Prince William Water collected quarterly samples for the Unregulated Contaminant Monitoring Rule 5 (UCMR5) in its East and West water distribution systems. Results indicated that Prince William Water's East system were slightly above the EPA's proposed Maximum Contaminant Level for both PFOA and PFOS. PFOA and PFOS were not present in the sampling performed for Prince William Water's west system.

Prince William Water will work with regulatory agencies and our wholesale water providers to ensure that we maintain the safety and high quality of our drinking water. Water systems have until 2029 to comply with the EPA’s stringent new PFAS limits.

You may be eligible for a courtesy adjustment on your account. Information on leaks and leak adjustments is available in the Customer Handbook.

There is a, non-refundable Application Fee for new service requests that will appear on the first month's bill. In addition, tenants must pay an Advance Payment Deposit that is included on the first bill. All Fees are outlined in the Customer Handbook.

Monthly bills include fixed service charges based on your meter size and consumption charges based on your monthly usage. Bills also include trash service for customers in the Yorkshire area who receive trash services through an independent contractor. 

The Property Owner is responsible for any repairs or replacements of Sump Pumps. 

We can assist the Property Owner with investigating an issue with a sump pump that was installed by Prince William Water. For more information please see the Customer Handbook.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of more than 6,000 manmade chemicals used in the manufacture of a wide variety of industrial and household products designed to resist heat, water, oil and stains. A wide variety of products are made with PFAS, including non-stick cookware, food packaging, personal care products and water-resistant apparel.

Four PFAS of note include perfluorooctanoic Acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorobutanesulfonic acid (PFBS) and hexafluoropropylene oxide dimer acid (HPFO-DA or GenX). In June 2022, the Environmental Protection Agency (EPA) released new lifetime health advisories for the four compounds.

Although their use has been phased out in the United States, the fact that these chemicals are very stable means that they tend to hang around in the environment for a long time. There is national concern about these chemicals entering our surface and groundwater drinking water sources.

Yes. On April 10, 2024, the EPA announced final national primary drinking water standards for six types of poly- and perfluoroalkyl substances (PFAS), including proposed Maximum Contaminant Levels (MCLs) for perfluorononanoic acid (PFNA), perfluorohexane-sulfonic acid (PFHxS), hexafluoropropylene oxide dimer acid (HFPO-DA or GenX chemicals), perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). The standard also establishes a hazard index (HI) for a mixture of two or more of the following: PFNA, PFHxS, HFPO-DA, and perfluorobutane sulfonic acid (PFBS).

According to the EPA, public water systems have five years (by 2029) to implement solutions that reduce these PFAS if monitoring shows that drinking water levels exceed these MCLs. Fairfax Water will ensure that our water meets these standards..

Water utilities are passive receivers of PFAS compounds, which are used in firefighting foam, industrial processes, and consumer products. Most humans are exposed to PFAS through food and consumer products while drinking water makes up a small portion of their total exposure. Peer-reviewed studies show that exposure to elevated levels of PFAS may lead to adverse health outcomes in humans.

Due to decades of use, PFAS are everywhere in the environment. Industrial sites might release PFAS into the water or air. Consumer and household products containing PFAS enter landfills and are washed down the drain. Because of their chemical composition, PFAS do not break down naturally and can be found throughout the environment in surface water, groundwater, air, and soil. They build up in the environment over time, eventually entering our bodies through food and drinking water.
