Is Salisbury Water Safe to Drink? What Every Homeowner Should Know

Yes, Salisbury tap water is safe to drink by federal standards. The municipal water system serves about 33,000 residents and operates under state and federal regulatory oversight, with no current federal violations on record. That said, Salisbury sits at the center of one of the most significant private-well PFAS contamination events on the East Coast, tied to a Perdue AgriBusiness facility, and the city’s own municipal supply has tested with PFOA and PFOS totals as high as 7.53 parts per trillion, approaching the thresholds that will require treatment under new federal standards taking effect in 2029. For most Salisbury homes, the question isn’t ‘safe vs. unsafe’ but how to think about regional PFAS exposure, above all for homes on private wells, and the trace contaminants that can enter at the tap from older household plumbing.

When Salisbury’s utility says the water is safe, that means it meets the EPA’s Maximum Contaminant Levels (MCLs) when averaged across the year. That’s a meaningful baseline, but there is more to take into consideration.

Salisbury’s water is supplied through a municipal system that draws from local Eastern Shore water sources and treats the supply through a conventional process of coagulation, sedimentation, filtration, and chloramine disinfection. The system operates under state and federal regulatory oversight, with routine sampling and reporting to keep water quality within compliance.

The distribution system is monitored continuously, with samples pulled from more than 30 locations across the city each month. Maryland’s Board of Public Works approved nearly $4.9 million in early 2025 to connect the Naylor Mill Village mobile home park, a neighborhood hit hard by regional PFAS contamination, to the city’s treated water supply, with completion expected by the end of 2026.

Sharp Water’s service area extends across the Delmarva Peninsula, including Cambridge, Dover, Easton, Elkton, Middletown, Milford, Salisbury, Smyrna, St. Michaels, and Princess Anne. Water quality on the peninsula varies widely between municipal supplies and private wells, and the regional PFAS contamination from the Perdue site has put both kinds of supplies under sharper scrutiny.

State officials discovered toxic PFAS in wastewater at a Perdue AgriBusiness facility in Salisbury in 2023, but nearby residents were not informed for nearly a year. Since then, testing has revealed that more than 350 private wells in the area contain PFAS, many at levels 10 to 100 times higher than standards for safe drinking water. At the Perdue facility itself, one sample location showed PFAS concentrations more than 340 times the EPA threshold.

Contaminated groundwater from the site is moving westward at a rate of one to two feet per day, pushing a wall of PFAS-laden water into residential areas that rely on private wells. The chemicals identified include PFOA, PFOS, and PFHxS, all linked in research to cancers, liver and kidney damage, and immune system disruption. More than 400 residents have joined a class action lawsuit against Perdue, and in June 2025 residents were still searching for answers as the community continued to work through the scope of the contamination.

Beyond the Perdue contamination, the City of Salisbury’s own municipal water supply has tested with PFOA and PFOS totals as high as 7.53 parts per trillion, approaching thresholds that will require treatment under new federal standards taking effect in 2029. The city applied for federal grant funding in January 2025 to construct PFAS treatment systems at both water plants, and Maryland’s Board of Public Works approved nearly $4.9 million to connect the Naylor Mill Village mobile home park to the city’s treated water supply. The project is expected to finish by the end of 2026 and underscores how even communities with compliant public water systems are facing costly infrastructure investments to address contamination that was not previously regulated.

The recent Salisbury Water Quality Report gives a detailed look at what’s flowing through your tap. Beyond the regulatory pass/fail, the data tells you what’s affecting taste, plumbing, and long-term exposure.

Recent system-wide testing puts HAA5 at 3.7 ppb and Total Trihalomethanes (TTHMs) at 3.8 ppb. Both sit far below their federal MCLs of 60 ppb and 80 ppb, an unusually low DBP profile that reflects the system’s source water and chloramine-based disinfection. The result is less DBP exposure at the tap than in many other markets.

Chlorine is essential for disinfecting water on its way from the treatment plant to your home. At about 1.0 ppm, Salisbury sits in the lower municipal range. Chloramine disinfection produces a different taste profile than chlorine alone and tends to be less aggressive at the tap, though some customers still notice taste and smell.

Recent testing showed no detectable lead at the 90th percentile, and copper at 0.10 ppm. Both are well below federal action levels. Lead and copper enter water from household plumbing after it leaves the treatment plant, so what comes out of an individual tap in an older Salisbury home can still differ from system-wide averages. Other trace constituents include barium at 0.164 ppm, nitrate at 6 ppm, fluoride at 0.4 ppm, beta and photon emitters in the range of 4.9 to 6.9 pCi/L, dibromochloromethane at 0.62 ppb, and asbestos at 0.19 million fibers per liter.

PFAS, often called ‘forever chemicals,’ are a growing concern across Maryland and throughout the country because these compounds break down slowly and can remain in water supplies for decades. PFAS exposure has been linked in some studies to increased risks of certain cancers, thyroid disease, immune system effects, developmental concerns, and elevated cholesterol levels.

Salisbury sits at the center of the issue. Recent testing of the municipal supply confirmed multiple PFAS compounds: PFOS at 6.875 parts per trillion, PFBS at 2.575 ppt, PFHxS at 2.35 ppt, PFHxA at 2.0 ppt, PFPeA at 1.9 ppt, and PFOA at 1.475 ppt. PFOS and PFOA totals run as high as 7.53 ppt, close to new federal limits taking effect in 2029. The Naylor Mill Village mobile home park, hit hard by regional PFAS contamination, is being connected to the city’s treated water supply through a $4.9 million Maryland-funded project scheduled to wrap by the end of 2026.

The bigger PFAS story in Salisbury is the contamination tied to a Perdue AgriBusiness facility, where firefighting-foam wastewater introduced PFAS into groundwater that is now moving westward at one to two feet per day. More than 350 private wells have tested for PFAS, many at 10 to 100 times safe-drinking-water standards, and the Perdue site itself showed concentrations more than 340 times the EPA threshold. Over 400 residents have joined a class action lawsuit.

Some homeowners choose to install advanced filtration as an additional layer of protection. Reverse osmosis systems and certain activated carbon filters are among the most commonly used technologies for reducing many PFAS compounds at the tap, and they are a strong consideration for any Salisbury household on a private well within the broader Perdue plume area.

Most water quality issues in Salisbury homes show up at the tap before they show up in a city report. If you notice any of the following, treat it as a prompt to test, not a reason to panic.

Salisbury’s water has a baseline taste from chloramine disinfection (chlorine measures around 1.0 ppm system-wide). A metallic taste can point to corrosion, a rotten-egg smell to sulfur or bacterial growth, and a sharper-than-usual chemical smell can show up around seasonal byproduct fluctuations.

A glass of water that looks cloudy and clears from the bottom up is just trapped air. Cloudiness that doesn’t clear, or a yellow/brown tint, can indicate sediment, iron, or manganese disturbance, which is more common after main breaks or hydrant flushing.

Pink residue is airborne bacteria thriving on soap scum (not from the water itself). Black residue can point to manganese accumulating in plumbing over time. Orange staining usually means iron, which is common in Eastern Shore groundwater systems and can show up in older fixtures.

Hardness wasn’t reported in Salisbury’s recent Water Quality Report, but Eastern Shore water often carries a moderate to high mineral profile. A sudden uptick in scale on fixtures, a water heater that runs louder than it used to, or rapid mineralization on dishes and appliances can signal that an existing softener needs service or that one is worth considering.

If Salisbury or Wicomico County issues a boil advisory, a PFAS advisory, or an exceedance notice, follow it immediately. For households on private wells inside the Perdue plume area, state-led testing programs are the primary way to find out whether your specific well is affected.

Not all water tests are designed to look for the same contaminants, and the right option depends on what you’re trying to learn about your home’s water.

Culligan’s free in-home water test is designed to identify common household water issues like:

This type of test is helpful for determining whether a water softener or filtration system may improve your home’s water quality. However, in-home testing is not intended to detect contaminants like lead or PFAS, which require laboratory analysis.

Certified lab testing is the best option for homeowners concerned about:

Lab testing is recommended for older homes, homes with young children, anyone on a private well in the Perdue plume area, or anyone wanting more detailed contaminant-specific results. Pricing varies depending on the contaminants being tested.

DIY water test kits can be purchased online through retailers. These kits screen for hardness, chlorine, pH, iron, and other basic water conditions.

While convenient, DIY kits are less comprehensive than certified laboratory testing and should be viewed as a basic screening tool rather than a replacement for professional analysis.

You don’t need to test your water every month, but there are specific moments when testing is worth doing.

Most of these cost nothing and reduce exposure, giving homeowners extra peace of mind.

Once you know what’s in your water, picking the right system is straightforward.

A water softener removes the hardness minerals like calcium and magnesium that cause scale buildup.

A whole-house filter reduces chlorine, sediment, and disinfection byproducts at the point where water enters your home, so every tap, shower, and appliance benefits.

An RO system installed under the kitchen sink polishes drinking and cooking water by removing lead, byproducts, and a long list of trace contaminants. RO is also one of the most effective treatments for PFAS at the tap.

If PFAS or other emerging contaminants are a concern in your area, advanced filtration can target these compounds at extremely low levels for long-term protection. Given the confirmed PFAS detections in Salisbury’s municipal water and the regional Perdue plume, this is one of the most relevant upgrades a household here can make, in particular for homes on private wells.

Sharp Water customers across the Delmarva Peninsula have options when it comes to choosing the right system for their home. With flexible rental, installation, and repair services, homeowners choose what best fits their needs and budget.

Since Salisbury water quality varies between city supply and private wells, and PFAS is a regional concern that demands certified testing, starting with a free at-home water test allows homeowners to evaluate what water treatment approach works best for their needs.
