Does Your Tap Water
on Delmarva Contain Fluoride?

Many communities across the Delmarva Peninsula are taking a closer look at fluoridation levels and motivations. As the conversation continues, it helps to understand how fluoride shows up in local water supplies and what it means for your home.

In 2015, the U.S. Department of Health and Human Services Agency (HHS) revised what defined acceptable fluoride levels:

“…water systems practicing fluoridation adjust their fluoride content to 0.7 mg/L (parts per million), as opposed to the previous temperature-dependent optimal levels ranging from 0.7 mg/L to 1.2 mg/L. There is no change regarding federal health officials’ strong and long-standing support regarding the value of fluoridation of drinking water.”

Water systems across the region follow federal guidance for fluoride levels. In Salisbury and surrounding areas, fluoride has been measured at approximately 0.4 ppm, which is well below the federal maximum contaminant level of 4.0 ppm.

This level is also below the commonly recommended target of around 0.7 ppm used in many municipal systems for dental health support.

Since groundwater flows through natural rock formations before reaching municipal wells, small amounts of fluoride can occur naturally in aquifer-based systems like those used throughout Delmarva.

The most common use for fluoride is supporting dental health. It has been widely shown to help prevent tooth decay, which is why it is commonly present in municipal water supplies across the country.

Fluoride became widely used in municipal water systems after its connection to dental health was established. Today, water systems maintain fluoride levels within a regulated range to balance benefits and safety.

In Salisbury’s case, the detected level of around 0.4 ppm falls comfortably within safe drinking standards, while still contributing to overall water composition.

While fluoride has long been supported by public health organizations, it is not without debate. Some studies have raised concerns about long-term exposure at higher levels, while others continue to support its role in preventing cavities.

Because of this, many homeowners across Delmarva are becoming more aware of what is in their water and exploring ways to control what they consume at the tap.

If your home has fluoridated water and you prefer to reduce it, there are treatment options available that specifically target fluoride.

At levels like those found in Salisbury’s water, fluoride is not considered a regulatory concern. However, some homeowners still choose to reduce it based on personal preference or overall water quality goals.

Standard filtration methods typically do not remove fluoride effectively. More advanced systems are required.

Reverse osmosis systems, for example, are designed to reduce fluoride along with other dissolved substances that may be present in municipal water supplies.

This makes them a strong option for improving drinking water at a dedicated tap.

Water quality testing in Salisbury shows fluoride levels at approximately 0.4 ppm, which is:

This means the water meets all regulatory requirements. However, even when water is compliant, substances like fluoride are still present. For homeowners who prefer to reduce or control what is in their drinking water, treatment solutions are still commonly considered.

Even though Salisbury’s water meets federal and state safety standards, many homeowners still want more control over what is in their water.
