Aberdeen, Maryland’s
Home for Water Softeners,
Water Filters, and Water Delivery

Yes. The City of Aberdeen reported that its drinking water met or exceeded all federal and Maryland drinking water requirements and had no contaminant violations. However, the report detected contaminants including nitrate, fluoride, chlorine, lead, copper, TTHMs, HAA5s, radium, and trace volatile organic compounds. Many homeowners choose additional filtration for improved taste, odor, and added peace of mind.

Aberdeen receives water from fourteen groundwater wells drawing from the Talbot Formation aquifer. The city also purchases supplemental water from Harford County and Havre de Grace, which are supplied in part by the Susquehanna River and additional groundwater sources.

Yes. Maryland’s Source Water Assessment determined that Aberdeen’s water supply is susceptible to volatile organic compounds (VOCs). Potential contamination sources were identified through site visits, land use mapping, and environmental reviews. The city also maintains a wellhead protection program to help protect groundwater resources.

No. Aberdeen reported no contaminant violations in its water production or distribution system during the reporting period. The city stated that all detected contaminants remained below applicable drinking water standards.

The City of Aberdeen’s most recent report did not list any PFAS detections within the city’s groundwater supply. However, supplemental water purchased from Harford County reported PFHxA detections up to 2.0 ppt. PFAS are commonly referred to as “forever chemicals” because they can persist in the environment for long periods. Many homeowners choose reverse osmosis systems to help reduce PFAS in drinking water.

Yes. Aberdeen reported nitrate at 2.43 ppm, which is below the federal drinking water standard of 10 ppm. Nitrate commonly enters groundwater through fertilizer runoff, septic systems, and natural deposits. Households with infants often pay particular attention to nitrate levels in drinking water.

The most recent Aberdeen Water Quality Report did not report arsenic as a detected contaminant in the city’s drinking water supply.

Yes. Aberdeen reported fluoride levels ranging from 0.17 ppm to 0.97 ppm, with an average level of 0.53 ppm. Fluoride may occur naturally and can also be added to support dental health. Some homeowners choose reverse osmosis systems when they want additional control over fluoride in drinking water.

Yes. Aberdeen reported total trihalomethanes (TTHMs) at 38 ppb and haloacetic acids (HAA5s) at 14 ppb. These compounds form when chlorine reacts with naturally occurring organic matter in source water. The reported levels were below federal drinking water standards. Activated carbon filtration can help reduce these compounds along with chlorine taste and odor.

Aberdeen uses chlorine to disinfect drinking water and protect against harmful bacteria and microorganisms throughout the distribution system. The city reported chlorine levels ranging from 1.22 ppm to 2.04 ppm, with an average of 1.65 ppm. While chlorine plays an important role in water treatment, some homeowners prefer filtration to reduce chlorine taste and odor.

The City of Aberdeen report does not provide a hardness measurement for the municipal water supply. Because Aberdeen relies heavily on groundwater wells, hardness levels can vary. A local water test is the best way to determine whether your home has hard water and whether a water softener may be beneficial.

Aberdeen reported a 90th percentile lead level of less than 1 ppb, well below the EPA action level of 15 ppb. No homes exceeded the action level during testing. Lead typically enters drinking water through household plumbing materials rather than the water source itself.

Aberdeen reported copper at a 90th percentile level of 0.315 ppm. Copper can enter water through household plumbing, especially when water sits in pipes for several hours. The reported level is below the action level, but a water test can help determine whether copper or other plumbing-related metals are present in your home’s water.
