Where Does Concord's Water Come From?

Concord has a mix of municipal water customers and properties with private wells. The public water system uses 6 groundwater supply wells and a surface water source located on the Acton/Littleton line. Concord’s municipal water system is linked with Acton and Bedford to provide emergency backup if ever needed.

Because much of the municipal supply comes from groundwater, its contents can vary between sources. Private wells can also be affected by the local soil and bedrock. Environmental conditions may contribute to hardness, iron, manganese, arsenic, and other water quality concerns. Testing is the best way to understand the water at your property before selecting a treatment system.

Common Water Quality Problems in Concord, MA

  • Iron & Manganese

    Iron and manganese occur naturally in Concord’s groundwater. They can cause brown, orange, or black discoloration and leave sediment behind in plumbing and water heaters.

    Iron and manganese are sources of sediment and discoloration in the municipal system. The Town periodically flushes water mains to remove buildup. Sometimes, this process can also cause temporary changes in tap water’s color and clarity.

    In private well water, iron and manganese can cause similar household issues. High levels may also contribute to bacterial growth followed by odor problems and slime accumulation in pipes, toilet tanks, and faucet aerators.

  • PFAS

    Per- and polyfluoroalkyl substances (PFAS) are man-made chemicals that can enter groundwater and surface water through various pollution sources. They break down very slowly in the environment and are often called “forever chemicals.

    Because PFAS in water cannot be detected by sight, smell, or taste, laboratory testing is needed to determine whether they are present. PFAS have been detected in Massachusetts public water supplies and across the country. The Town of Concord has been developing long-term PFAS mitigation plans for affected supplies.

  • Lead

    Lead can enter drinking water through old service lines, solder, fixtures, and household plumbing. Most Concord residential water service lines are made out of copper, lead, or plastic. Some service line materials remain unknown. The Town is making an ongoing effort to identify and replace lead service lines.

    While Concord is working with customers to remove all lead service lines, the Town cannot control the plumbing materials used in each resident’s home. If you live in an older home or are unsure about your plumbing, laboratory water testing can check for lead. Depending on the results, a properly selected water filtration system can help reduce exposure.

  • Hydrogen Sulfide Gas (Rotten Egg Odors)

    A rotten egg smell in water is often associated with hydrogen sulfide gas. This problem is common in private well water and can occur naturally as groundwater interacts with organic material. Sulfur-reducing bacteria in plumbing or well systems and water heaters in need of service can also cause the odor.

  • Sodium, Chloride & Dissolved Solids

    Sodium, chloride, and total dissolved solids (TDS) in Concord drinking water can come from naturally occurring minerals in local groundwater and surface water. Supplies may also be influenced by winter road salt runoff, which may carry sodium and chloride from roads, parking areas, and driveways into local water sources.

    Higher chloride levels can create a salty taste and may contribute to corrosion. Elevated TDS can affect taste, as well, and, depending on the dissolved minerals present, may contribute to scale or mineral residue.

Other Water Quality Concerns in Concord

Other issues that may affect Concord, MA, water include:

  • Hard Water: In the 2025 water report, Concord’s municipal water was considered moderately hard on average. Hardness can cause scale, spots on dishes, buildup in water-using appliances and plumbing, dry skin, and other issues.
  • Arsenic: This naturally occurring contaminant can be found in some Massachusetts groundwater and cannot be detected by taste, smell, or appearance.
  • Radon: Radon can be found throughout Massachusetts. It can dissolve into private well water and be released into indoor air when the water is used.
  • Turbidity: Sediment and suspended particles can make water look cloudy or dirty. Turbidity may increase after disturbances to wells or municipal water mains.
