For more information on your municipal water, visit the U.S. Environmental Protection Agency:
Somersworth Water Works Municipal Water Company and EPASomersworth Water Works Municipal Water Report Info
EPA guidelines help ensure your water meets strict safety standards. The Environmental Protection Agency monitors municipal water suppliers and requires regular testing for various contaminants.
Local water utilities must provide annual Consumer Confidence Reports detailing water quality information. These reports include source water assessments, detected contaminants, and compliance with regulations.
The EPA sets Maximum Contaminant Levels (MCLs) for substances that may pose health risks, with ongoing research to address emerging concerns like PFAS chemicals.
Municipal Water Utility Company FAQ

For more information on your municipal water, visit the U.S. CDC:
Somersworth Water Works Municipal Water Company and CDC- Why does my water appear cloudy or milky? This appearance typically results from tiny air bubbles in the water, which are harmless. Allow the water to sit for a few minutes—the cloudiness should clear as bubbles rise and dissipate. If cloudiness persists, please contact us for inspection.
- What causes spots on dishes? These spots typically result from mineral deposits (hard water) remaining after water evaporates. Most dishwasher rinse agents can effectively eliminate these spots.
- Is a water softener necessary? This depends on your water's hardness level. While hard water isn't harmful to health, it can affect appliance efficiency and cleaning effectiveness. Note that most softeners increase sodium content, which may be important for those on sodium-restricted diets.
- Should I install a home filtration system? According to EPA guidance, home treatment systems are rarely needed for health reasons. Most are used to improve taste, odor or appearance. If you choose to install one, carefully follow manufacturer maintenance instructions to avoid creating water quality issues.
- Why does my coffee look oily? Clean your coffee maker with a vinegar-water solution as recommended by the manufacturer. Regular cleaning prevents buildup that affects appearance and taste.
- What causes hot water odors? The most frequent source is the water heater itself. If cold water smells fine, check your water heater temperature setting and maintenance schedule. Contact us if odors persist or appear in both hot and cold water.
- What causes discolored water? Discoloration typically comes from natural organic materials, minerals, or pipe sediment. We regularly flush the water system to remove buildup. If you experience discolored water, run your taps until clear. While usually harmless, please report persistent discoloration.
- Is bottled water better than tap water? Both must meet the same quality standards, but municipal suppliers undergo more frequent testing and reporting. Some prefer bottled water's taste or choose it for specific health concerns. However, tap water costs approximately 1,000 times less than bottled alternatives.
- Why do hydrants get flushed? We conduct regular system flushing to remove mineral deposits and sediment from pipes and ensure proper water circulation. Hydrants are also opened during fire-flow capability testing.
- Why is water disinfection necessary? Disinfectants prevent the spread of waterborne diseases. Before modern disinfection practices, illnesses like cholera, typhoid fever, and dysentery were common. Water disinfection has dramatically improved public health safety.
- How can I reduce chlorine taste/odor? We disinfect water to ensure it's free of harmful bacteria. To minimize chlorine taste or smell, try refrigerating water before drinking. A pitcher filter can also help improve taste while maintaining safety.
