Common Water Issues in Rockville

Solutions For Your Water Quality Problems

The main source of water for the city of Rockville is the Potomac River. In addition, the city also sources a portion of its water from the Washington Suburban Sanitary Commission, as well as several other surface and groundwater sources. Municipal water is treated at the city's Rockville Water Treatment Plant, which produces 8 million gallons a day for residential purposes. Because Rockville's water comes from heavily populated areas and is likely to be exposed to contaminants and toxins as it moves over land and underground, water is rigorously disinfected and treated.

Hard, Poor-Quality Water

Dissolved iron and other minerals are absorbed on water's journey from its source to Rockville's taps, making it hard and compromising its quality. While not dangerous, hard water can contribute to a number of frustrating household problems, including:

  • Malfunctioning appliances due to sediment and buildup
  • Hard-to-clean residue in kitchens and bathrooms
  • Itchy, dry skin
  • Stiff, scratchy laundry
  • Unpleasant or bitter taste

Lime Buildup or White Scale

Limescale is a hard, off-white buildup that forms on many household items due to the dissolved minerals in hard water. Limescale can cause:

  • Sediment and scum on bathroom and kitchen appliances
  • White scale rings around bathtubs
  • Clogged faucets and showerheads
  • Buildup in heating and cooling units
  • Chalky deposits found on kettles, pots, and pans

Spotty, Cloudy Glassware

Dishes, glasses, and silverware cleaned in a dishwasher that runs on hard water can come out appearing:

  • Spotty
  • Cloudy
  • Streaky
