PFAS in Maryland Water: What Eastern Shore and Anne Arundel Homeowners Need to Know in 2026

PFAS — often called “forever chemicals” — have become one of the hottest topics in Maryland water quality this year. If you live on the Eastern Shore or in Anne Arundel County and rely on a private well (or even municipal water), you’ve probably heard the term and wondered what it actually means for your family.

What Are PFAS? PFAS is a large family of thousands of man-made chemicals that have been used since the 1940s to make products resistant to water, grease, and stains. You’ll find them in non-stick cookware, water-repellent clothing, food packaging, firefighting foam, cosmetics, and many industrial processes.

The problem? These chemicals are extremely persistent. They don’t break down easily in the environment or in the human body. Over time, they can build up in soil, groundwater, crops, livestock, and people.

Why the Concern in Maryland? Maryland has seen PFAS detections in private wells, public water systems, schools, and agricultural areas. On the Eastern Shore, concerns often connect to legacy industrial activity, wastewater, and the land application of biosolids (treated sewage sludge used as fertilizer on farms). Anne Arundel County has proactively tested its drinking water and states it meets current standards, but many homeowners with private wells remain unsure about their own supply.

Recent state funding (nearly $4.9 million approved in early April 2026) is helping extend public water to a PFAS-affected mobile home park near Salisbury, showing that real issues exist and are being addressed at the community level.

Health and Environmental Impact Studies link long-term PFAS exposure to increased risks of certain cancers, liver effects, immune system changes, thyroid issues, and developmental concerns. Because they accumulate over time, even low levels in drinking water can add up. Children, pregnant individuals, and those with private wells in rural areas can be more vulnerable.

Environmentally, PFAS can affect farms, rivers, and the Chesapeake Bay watershed when they leach into groundwater or runoff.

What’s Changing in 2026? The Regulatory Crackdown Maryland lawmakers are actively addressing PFAS through the 2026 legislative session:

• Biosolids (sewage sludge) rules: Bills like SB719/HB925 aim to restrict land application of biosolids with high levels of key PFAS compounds (PFOA + PFOS). Starting in 2027–2028, material above 50 parts per billion would be prohibited from agricultural use, with additional restrictions and monitoring for levels between 25–50 ppb. This targets one major pathway of ongoing contamination on farmland.
• Product phase-outs: Other bills push for restrictions on intentionally added PFAS in consumer products like personal care items, textiles, and more.
• Federal side: The EPA maintains strict limits on PFOA and PFOS (4 parts per trillion each) in drinking water, with monitoring requirements continuing and compliance deadlines extended in some cases to 2031. Public water systems across Maryland are investing millions to meet these standards.

These changes show momentum toward reducing new sources of PFAS, but existing contamination in soil and groundwater will take time to address.

What Can Homeowners Do? If you have a private well (very common on the Eastern Shore and parts of Anne Arundel), the responsibility for testing and treatment often falls on you. Here are practical steps:

1. Test your water — Basic well testing is a good start, but specific PFAS lab testing provides clearer answers (especially if you’re near farms, industrial sites, or known contamination areas).
2. Understand your system — Municipal water in Anne Arundel is regularly monitored, but private wells vary widely.
3. Consider filtration options — For drinking and cooking water, technologies that can significantly reduce PFAS include multi-stage systems with specialized media or reverse osmosis (RO), which studies show can remove 90–99% of many PFAS compounds. Whole-house options can provide broader protection for bathing and laundry.
4. Maintenance matters — Any effective system needs regular filter or membrane replacement to keep performing well.

Reducing exposure at home is one of the most direct actions families can take while larger-scale cleanup efforts continue.

Bottom Line PFAS are a complex, long-term challenge, but awareness and smarter regulations in 2026 are positive steps for Maryland. Knowing what’s in your water gives you the power to make informed decisions for your household.

If you’re curious about your own well or tap water on the Eastern Shore or in Anne Arundel County, starting with a basic water quality check is often the smartest first move.
